Unk’s Astroware Top 10
As y’all know, muchachos, I am a confirmed astroware
fanatic. I don’t have every single astronomy program ever to come down the
pike, but I have more astronomy software on my hard drive(s) than humans should be
allowed to have. And while I ain’t got the latest and greatest of every single biggie,
I’ve at least got an older version of almost every one.
So what? The end of the year seems like a good time for taking
stock and making lists. Herewith, then, are Unk’s top 10 astroware programs. In
no particular order. I couldn’t quite cipher that out…
Cartes du Ciel
I didn't try the first release of Patrick Chevalley’s “CdC” as its aficionados fondly call
this famous planetarium program. I first heard about it from my late
friend and astroware guru, Jeff Medkeff, in the late 1990s, but he said the
early Cartes really wasn’t quite ready for prime time. Then, a year or so later,
Jeff changed his tune, opining that this freeware program could be big, real big.
And it is. Patrick first got the program off the ground in 1997,
and hasn't stopped improving it since. The most significant update since the
early days probably being version 3, which came out a few years back and put the
program on the level of any commercial soft. Cartes du Ciel was completely rewritten at that time to improve
performance and to (somewhat) streamline its User Interface. Two new versions were also released at that time; one for Macintosh and one for Linux.
What can CdC do? Almost anything, if not quite everything. Certainly,
anything your old Unk wants to do at the telescope. No, it don’t offer stuff
like plate solving, but that sort of thing is way beyond your silly old Uncle.
The good news for folks who do want to do things like that? CdC interfaces
easily to other programs. It is the favorite “front end,” for example, of the
users of the mount control driver, EQMOD.
CdC |
“But how many objects, Unk? And how does it look?” CdC
features tons of catalogs past the NGC to include the huge PGC galaxy catalog.
It can use both the Hubble Guide Star Catalog and the larger/better UCAC star
catalog. Cartes’ strength when it comes to catalogs isn't what it comes with,
but what can be added to it thanks to its open, friendly nature. Don’t see the
catalog you want? If you have the data, it’s easy to build one with the included CATGEN utility.
Well, unless you are Unk, who depends on more computer literate folks to do such things.
Looks are admittedly the sticking point for some of y’all
when it comes to CdC. It looks OK,
but as you can see in the screenshot here, it is plain vanilla plain. But is that always a
bad thing? Out on a dark field, “pretty” sometimes also means “not very
legible.” Cartes is very easy to decipher with your display a dimmed down red.
Stellarium
Unk was a Stellarium skeptic for the longest time. I
kept hearing people going on and on about this new freeware program that was supposedly
better than Cartes du Ciel. It
was the Big Thing on the cotton-picking Cloudy Nights BBS for the longest time. I was skeptical, yeah, as I always am when it comes to the supposed more
better gooder, but I finally got around to trying the program, and I liked what
I saw. It’s not better than CdC, and
in some ways it is not as good, but it is
quite an achievement and is a novice's dream come true.
Unlike Unk’s much-loved CdC, Stellarium is very pretty. While I wouldn’t call it photorealistic
on the level of TheSkyX or the upper
levels of Starry Night, it is
attractive and the comparison between it and the plain Cartes in that regard is
like night and day. The program is also very responsive on most machines, and
it’s like heaven for Joe or Jane Newbie to be able to grab the sky with the
mouse to move around in Stellarium. It’s also heaven for them—and maybe for old
timers too—to be able to issue commands from a few big toolbar buttons instead
of scratching their heads at Cartes' multiple menus, tiny buttons, and icon
bars. If that were all there were to the story, Cartes du Ciel would be history.
Stellarium |
But that ain’t the whole story. Stellarium is just fine in the house for quick “What’s up?” checks.
And while I don’t doubt casual observers will find Stellarium OK for use
at the scope, those of y’all who intend to go real deep may be a bit annoyed
with the program’s limitations, as will those who want to control a scope with
it.
How many deep sky objects does Stellarium have? Nowhere is that stated. I finally got the chance to ask one of the authors "What's in there?" on the Cloudy Nights BBS. His taciturn answer? "NGC, IC, M, and C." The "M" is no doubt "Messier," and I assume the "C" is "Caldwell," Patrick Moore's (short) catalog. In other words, don't look for PGCs or UGCs or even Kings or Bochums; you ain't gonna find 'em. Unfortunately, there is no way to add more catalogs to Stellarium at this time. Stars are no
problem. You can download (from within the program, in nine parts) an unnamed
star catalog consisting of millions of stars.
More annoying for some of y’all may be the program’s rather
rudimentary scope control system. It has built in drivers, but only for a
relatively few telescopes—Celestron, Meade, Losmandy, and SkyWatcher and that
is about it. That’s OK for many folks, but if you want to use something other than those scopes, it gets a little hairy.
You’ll need not one but two outboard programs if your scope/mount ain't on the list. ASCOM,
natch, and another separate program that allows Stellarium to talk to ASCOM, Stellarium
Scope. Wouldn't it have been best to forget built-in drivers and make Stellarium an ASCOM compliant program?
Also, you may find the scope control commands—Press CTRL-0 to go to the
currently selected object—a wee bit rudimentary.
Still, there is no denying Stellarium is an incredible achievement. Sitting there watching as
artificial satellites streak across the program’s lovely sky (right where they
should be) is, for example, not something you want to miss. Even if this
does not become your most used program and even if you never actually use it in
the field with a telescope, you want it on your box. Like Cartes du Ciel, Stellarium
is available for Macs as well as PCs, so there’s really no excuse
for you not to have it.
TheSkyX
TheSkyX |
Let me preface this by saying I don’t own a copy of TheSkyX. Not the real SkyX, anyhow. I might
someday, however. Perhaps not the rather expensive ($329.00) TheSkyX Professional, but maybe Serious
Astronomer, the next click down. How do I know I’ll like it enough to spend
just under 150 freaking dollars for it, then? The DVD that came in the box with my
new VX mount last year.
On that DVD was a lower than low, lower than the Student
Edition, version of TheSkyX, TheSkyX First Light Edition. This was
nothing new. Software Bisque has had low-levels of their programs bundled in
with Celestron gear for years and years. Sounded purty ho-hum to me, and I
almost tossed the DVD in the round file as I was bustlin’ around getting ready
for the 2013 Deep South Regional Star Gaze Spring Scrimmage.
Good thing I didn't. Good thing I was a mite bored when
my packing was done and decided to insert the disk into the kitchen computer’s
DVD drive. As I told y’all here, First Light
is now my favorite quick look program. It is better than Stellarium for that purpose—all I have to do is mash a N, S, E, or
W. button to immediately view the horizon of my choice. I don't have to waste time dragging the sky around with the consarned mouse unless I want to. First Light is, in fact, the best quick-look
soft I’ve used since my beloved and long-lost SkyGlobe
3.6.
It wasn’t just the utility of the program for sky checks
that impressed me; it was its totally redesigned User Interface. TheSky6 was in many ways a fantastic
program, but it never endeared itself to me because of its overly complicated
UI. Yes, I know the higher versions of TheSkyX
will have tons more features than First Light, but examining their screen shots
and having a quick brush with a buddy’s Professional version shows me Serious
Astronomer and Professional share the clean, easy interface of the humble First
Light Edition. For you Apple stalwarts, TheSkyX in all its versions is available for Macs as well as PCs.
Starry Night Pro Plus 6
Starry Night Pro Plus |
I really do love Starry
Night Pro Plus. In some ways that is surprising, y’all. Like TheSky 6, its User Interface is a mess
with all the grace of an elephant in ballet shoes. There are tool-bars, and
menus, and buttons galore and there is no discernible pattern to anything.
There are also a few minor bugs still resident in the final (I presume) update
of v6. But I use the program frequently. Maybe even more than dagnabbed Cartes du Ciel.
Why is that? It just does so much, looks so fraking purty, and performs so well. There are
not too many astronomy programs, for example, that will pull up the Clear Sky
Clock for your current location. Or show you a satellite weather map. I was a
little concerned, when I first got the soft, that all those tons of features
would make it sluggish. Nope. Drag the sky around with your mouse and you will
find smoothness and speed fully the equal of the much smaller and simpler Stellarium.
One huge draw, I gotta admit, is the Real Sky feature of the
Pro Plus version. That came from a now dead program, Desktop Universe. Some dudes took many, many medium/low resolution
CCD images of the sky and stitched them together to form the sky background of
their planetarium. Desktop Universe wasn't much good in most other respects, but its
photographic sky background was something to see.
When DTU failed, its remains were sold to the then-owners of
Starry Night who folded it into the
top version of their program. It is real
cool, y’all, to zoom in on the sky and see the heavens in photographic glory.
The only minus is the limited resolution. Zoom in too much and everything
fuzzes out. But that’s OK; the normal computer graphic stars and objects—which are just as good as those of any other top planetarium—take over then.
The only bummer? SNPP 6, as above, is not quite there. The bugs
and an unwieldy UI see to that. How about the new kid on the block, Starry Night Pro Plus 7? I am happy to
see the current owners of the program (and SkySafari),
Simulation Curriculum, continuing to develop Starry Night. BUT…from what I hear
the new one was released before it was quite ready and may not be quite ready
yet. Would I spend an amount almost up there with TheSkyX Professional for Starry Night Pro Plus 7? Probably not, but
you never know. If they can improve on SNPP 6 Plus even a little, I would be
awfully tempted, y’all.
SkyTools 3
SkyTools' Interactive Atlas |
And with that, we are out of planetarium programs, leastways
the ones your old Uncle has, likes, and uses. What’s left? Well, for one thing,
planners, programs that help you compose
observing plans. I sometimes hear people complain about the “learning curve”
involved in getting to know SkyTools 3. Usually, however, these are folks
who haven’t spent much time with the soft. Yes, it will do a hell of a lot, but
at first boot-up, it is one of the least intimidating looking programs I know
of, and one of the easiest to begin using in simple fashion.
When you start up ST3 for the first time, what greets you is
a familiar, friendly-looking spreadsheet not much different from the one you
use at work to report travel expenses. That is exactly what SkyTools is, a spreadsheet front end
backed by a humongous database of millions of stars and over a million deep sky
objects (from many, many cross-referenced catalogs).
Yes, the program does a great number of things; everything
from telling you when the next lunar eclipse will occur to figuring out how
much exposure you will need for a particular deep sky object with your sky,
scope, and camera. But beginning to use it doesn't necessitate learning to use
all these things—not at first. The program comes with ready-made observing
lists, and more are easily downloadable from within the program. Load up the
Messiers, click the “observed” field on an object’s spreadsheet entry when
you’ve seen it, click “log” to enter your observation, and you are using ST3 productively
from the get-go.
How about star charts? Typically, planners have lagged
behind planetariums in that respect, and in some ways, that is still the case. SkyTools 3’s sky is neither as
photorealistic as Starry Night’s, nor is it quite as interactive, despite being
named the “Interactive Atlas.” In practice, that doesn't hurt a thing. The Interactive
Atlas is like a cross between a print atlas, albeit one much, much deeper than
even Millennium Star Atlas, and a
planetarium program. For actual use in the field, I put it second to no other
charting system, including the top levels of TheSkyX and Starry Night.
When I’m using it, I’ve never wanted for better.
Don’t get me wrong, either; the Interactive Atlas is not
ugly. It’s better looking, for example, than poor old Cartes du Ciel, for sure. No, you can’t grab the sky and move it
around with the mouse, but the chart controls are smooth and responsive. Best
of all, on a dark observing field, SkyTools
Interactive Atlas is easy to read.
The greatest recommendation I can give SkyTools 3 is that it is the program that allowed me to
observe/image all 2500 Herschel objects in three years, a right good
accomplishment given our weather in the Swamp. The program never crashed or
misbehaved and never got in my way. It just worked.
Deep Sky Planner
Deep Sky Planner |
I could no doubt have used Deep Sky Planner for the
Herschel 2500 instead of ST3 and been just as happy and productive. The reason I didn't was
that by the time silly old Unk figured out how good DSP is and had glommed onto
a copy, the H-Project was well underway and I didn’t feel like swapping ponies
in mid-stream.
In most ways, DSP is much like SkyTools—it is a spreadsheet front end for a gigantanormous
database. There are differences, however. The program is a little more “Windows
like,” using a more standard menu layout than ST3. It is also more mouse
oriented, allowing you to drag and drop items hither and yon. I also like the
default font size of DSP: nice and big
and easy for poor old Unk’s peepers to read when the screen is filtered a dim
red. The big difference between SkyTools
and Deep Sky Planner, though, is the
charts. DSP doesn't have any.
Which don’t mean you can’t click on a list object and see it
on a sky map. DSP just doesn't have a built-in charting engine. The program
interfaces to most popular planetariums:
Cartes du Ciel, Starry Night,
TheSky, and more. I am somewhat torn about that. I do so love ST3’s
Interactive Atlas, but I can set up DSP so that when I click on an object up
comes a Starry Night chart centered
on my fuzzie. Those of y’all not wanting to learn a new charting system may really
like this aspect of DSP.
Nebulosity
While much of the computer software amateurs are using is
designed to draw sky charts or compose observing lists, applications for
astrophotography are a close runner up. Since I use a DSLR most of the time, I
need a program that will allow me to acquire and process images with my Canon,
and Nebulosity
is that program.
Nebulosity |
While the soft supports quite a few astronomy-centric CCD
cameras, I would guess most of the folks using Nebulosity are shooting the sky with Canon DSLRs. Why do you need a
computer to image the sky with a DSLR, anyhow? Why not just hook up a remote
release and fire away?
You could do that, but using a program to run your camera is
more effective. “Tethering” (as we call it in the terrestrial photography biz)
your Canon—Canons are the only DSLRs currently supported by Nebulosity—to a PC or Mac helps in a couple of ways. First, you can
focus with the big screen of your laptop, which beats the tar out of focusing
with the camera’s small screen or—horrors—through its dim viewfinder. Nebulosity also allows you to store your
images on your hard drive rather than on the DSLR’s memory card and saves them
in the astronomy-standard FITS format.
It doesn’t end there with Neb; it contains some awesome
stacking and processing tools. It's excellence in that regard means you may want the program even if you use a DSLR other than a Canon. Bottom-line-a-roony-o? Unk ain’t much of
an astrophotographer, but Nebulosity
allows me to be all the astrophotographer I can be. Nuff said.
Registax 6 and AutoStakkert
and FireCapture
No, this ain’t Unk’s sneaky way of getting a couple of extras
into the top ten. Not entirely. For planetary observers, these three go
together like red beans, rice, and sausage. Registax
6 was for years the unchallenged king of planetary image stacking. A little
over a decade ago, amateurs discovered the way you make high-resolution lunar
and planetary images is to take many frames with a high-speed camera and stack
the best together to form a final image. There’s more to Registax than stacking, however. Its image sharpening tools, its
“Wavelet” filters are unmatched for working magic on your images, for bringing
out more detail than you imagined was there.
Not long ago, I began hearing about another one, another
freeware program like Registax. This one, Autostakkert,
was reputed to produce even better results. Could that possibly be? Yep. Not
only do the image stacks I produce with Autostakkert
seem slightly better—better registered with maybe a better frame selection—it
is a bit easier to learn to use than the somewhat daunting Registax. Registax ain't
left out of the party, however. Once you stack with Autostakkert, you will still want to run the result through Registax's sweet
wavelet filters.
Registax |
In order to process planetary images, you gotta have planetary images. The best program
I’ve found for image acquisition is the (free) FireCapture. Despite its name, it works with USB connected planetary cameras and webcams. See this here for a fuller description
of the program’s crazy-good features and tools, but let me say rat-cheer that
I’ve been doing webcam/planet cam imaging for nigh on a dozen years, and no
program has worked as well for me for image capture as FireCapture.
Virtual Moon Atlas
Unk, as you may know is a confirmed lunatic. I am also a
frequent Moon observer and have been since I began in astronomy dang near fifty
years ago. When computers hit amateur astronomy big-time twenty years ago, I
began wishing for a “A Megastar for
Moon observers.” That is, I wanted a lunar charting program with the depth of
the old deep sky powerhouse, Megastar.
Took a while for that to happen, but eventually Patrick Chevalley, CdC’s author,
teamed with lunar expert Christian Legrand to do that very thing.
The result was VMA. It’s like somebody stuffed the Rukl
Lunar Atlas into a PC, but didn’t stop there, adding more features, more
details, and tons of images from professional lunar references like the Lunar
Orbiter atlas. There are several other computer lunar atlases, including a
commercial one for PCs and several for smart phones and tablets, but nothing
has realized Unk’s wish as fully as VMA. Like CdC, Virtual Moon Atlas is free and available in a Mac version—and believe me, y’all, you’ll dang sure want to run this one on your
Mac.
RSpec
Now for something completely different. I’m pretty sure most
of us amateur astronomers occasionally dream of contributing to science—or at
least getting a taste of what it’s like to go beyond “just looking.” RSpec will dang sure allow you to do the
latter, and may even let you do the former. It is designed not just to allow
you to obtain and analyze the spectra of stars and other objects, but to do
that simply and well.
Virtual Moon Atlas |
Do you remember the old commercial “So easy even a caveman
can do it!”? This program, amazingly, is so simple even Uncle Rod has been able
to use it to take spectra of bright stars. Rspec
can take you much farther than that, though. Coupled with a diffraction grating
or an honest to god spectrograph, folks with a lot more talent than Unk are
using it to do things like measure the redshifts of distant galaxies. If you are
wanting to try something different, RSpec just might be it. It is also
inexpensive and as professionally done as any software—astronomy oriented or
not—I have ever used.
Runners Up
Not every contestant, no matter how beautiful and talented,
will be standing up there onstage when the new Miss America is named, and not
every program can be in the top ten for Unk’s astroware beauty pageant. These
are the ones that I like a whole, whole lot but ain’t quite good enough to be in the top ten.
EQMOD, is the
ASCOM driver that allows you to run your Synta SynScan (Atlas, EQ6, etc.) mount
without a hand controller, and do it better than with the “real” hand control.
It is a runner up only because it is not really a program, but just a driver.
But what a driver. It is a staple of
21st Century amateur astronomy. Got an Atlas or a Sirius? You want EQMOD.
NexRemote is like EQMOD, but for Celestron branded mounts. It
is a fantastic program I’ve used for over a decade. It simulates the NexStar HC
on your PC (only) and does things the NexStar hand paddle cannot do. Why is it
down here, then? Because it is apparently no longer supported by Celestron.
There’s now a Plus NexStar HC, an improved hand control, but over a year down
the road, there’s not been a peep out of Celestron about a Plus NexRemote or even an update to the
existing version. Damn shame.
RSpec |
HeavenSat is for folks like Unk who’ve been space crazy since
they were younguns. It’s also for people who just want to view and identify
artificial satellites. There are plenty of programs, including plenty of other free
ones, that will make satellite predictions, but few are as easy to use or
feature such beautiful displays as HeavenSat.
Lunar Phase Pro is now in Version 2, but it doesn't look much
different to me than my version 1.10 copy. And that is a good thing; the
program is perfect just the way it is. This little soft just keeps chugging
along year after year informing us lunatics as to the current circumstances of
the Moon—phases, eclipses, libration, rise and setting times, and more. It’s
attractive and fast and inexpensive and if you are a Moon observer this will be
a bread and butter program for you, I guar-ron-tee.
AstroPlanner is, natch, a
planning program and a very good one. If there’s a single down-check to it for moi, it’s just that it’s really best on
a Macintosh in my opinion, and I ain’t got a Macintosh. Certainly the Windows
version ain’t nothing to sneeze at, neither, and has got many fans—as it
should.
Deepsky is also a planning
program, and it was one of the first programs of that type on the market. By
all rights, it should be up there with the other two. Unfortunately, it’s been
badly in need of attention—considerable updating—for a while. I hope its talented
author, Steve Tuma, does that, since this program still has some features
nothing else does.
Eye and Telescope is yet another planner, and it is at the
other end of the spectrum from Deepsky;
it is on its way up the ladder, not down. It’s a few years old now, and
while it still needs just a wee bit of tweaking, I would not be at all
surprised to find it in the Big 10 next time. I know I liked it from the first.
PHD Guiding is famous and it is great. So why is it a runner
up? Simply because it’s, well, kinda simple. All it does is guide your telescope
for long exposure imaging, but it does that like no other soft. Not even the
most expensive pay-to-play programs, like Maxim
DL. Need I say more?
And that is it for this time. I don’t know that I’ll make
this Top Ten Pageant a yearly affair, but maybe. Depends on how many astroware
authors let me know about their new stuff and how many of you, muchachos, tell
me about your faves that I overlooked. Hell, you can even preface your comments with, “Uncle Rod, YOU BLOCKHEAD!”
Next Time: More My Favorite Fuzzies...

Amateur Astronomy the Old Fashioned Way with Betty and Me
“The best telescope is the one that gets used the most.” “The
older I get, the lazier I get.” Ain’t both of those things the freaking truth, and especially the latter, muchachos? As Gaia has rolled around ol’ Sol yet another
time, I’ve found myself increasingly less likely or willing to set up my 12-inch
Dobsonian or even my 8-inch SCT for a quick backyard gander at the Moon—or
anything else.
Something else that has increased as the years pass is my
nostalgia for the things of my youth—or the things I wish I’d had as a youth. Like those luscious Unitron refractors of
yore with their long, gleaming white tubes. You can’t go home again; the stream
of time flows on, leaving the past behind and inaccessible. Or so it is said, anyhow. Sometimes, however, you can
at least get a taste, a whiff, of that past. Which happened to me via an
unexpected gift.
A few weeks
back, I received a semi-vintage and spiffed-up Celestron C102
from my long-time observing companion, Pat Rochford, as a house-warming gift not long after we moved into
the New Manse in May. A C102 ain’t a Unitron. But it is at least in the spirit
of those icons of refractor-dom, which your old Uncle, like every other
space-smitten little kid dreamed of owning in 1965 but could never afford.
“A Celestron refractor,
Unk? I thought Celestron was all about SCTs.”
Not at all, Skeezix, not at all. Celestron’s C102 goes all the way back to the
early 1980s. In them days, Celestron was selling considerable Vixen gear. That
Japanese manufacturer was highly regarded by amateur astronomers of the time,
and Celestron had begun selling Vixen’s Super Polaris mount with one of its C8
models. Before long, the company expanded their Vixen offerings to include a
couple of that company’s Newtonian reflectors and several refractors including a
4-inch achromat, the C102.
Despite the 1980s being the age of Dobsonians and SCTs, the
C102 was highly regarded. While it was an achromat and suffered from excess
color—purple halos, that is—on brighter objects, its reasonably long (by
today’s standards) focal ratio of f/10 kept that to bearable levels. The only
fly buzzin’ in the C102 ointment was that the Vixen Super Polaris mount, which
was more than sufficient for the C8, was stressed by the long tube of the
4-inch refractor.
It took a while for Celestron to rectify that shortcoming,
but rectify it they did in the early 90s when they began selling the C102 on
Vixen’s improved medium German equatorial, the Great Polaris, which is the
ancestor of all the Chinese “GP clones” with us today including Celestron’s CG5s
and Advanced VXes. The mount, while not overkill,
was more than sufficient for the C102.
“And the C102 lived happily ever after, continuing to meet
the wants and needs of decades of achromatic refractor fans.” Not exactly. By
the mid-90s the bloom was off the Vixen rose for Celestron. Prices for the
Japanese maker’s gear were climbing at the same time the Chinese company
Synta was coming on strong. In 1998, Celestron replaced the Vixen Great
Polaris, both for the C102 and for its GEM-mounted C8, with the ubiquitous
Synta EQ-4, which Celestron dubbed the “CG5.” They didn’t stop there.
Henceforth, Synta would also make the refractor’s optical tube assembly.
Was this new C102 an improvement? No. It was a cost saving
measure, and there was good and bad in the new model (which looked almost
identical to the GP-C102). The good was that, almost unbelievably for those of
us who’d thus far looked askance at Chinese refractors, the optics in the
Synta-made C102 were virtually indistinguishable from those in the Vixen. Maybe even a bit better. The
OTA itself? The focuser was no great shakes, but it was an OK rack and pinion.
The dirty little secret? The Vixen focusers weren’t so hot, either. Not hardly.
The mount was a different story. The early manual CG5s have
little to do with the latter day goto CG5 so beloved of cost-conscious amateur
astronomers. The wooden tripod was history, replaced with an extruded aluminum
job just this side of flimsy. What little smoothness there was in the
declination and right ascension axes was attributable to the infamous Chinese
glue-grease, which was applied in large dollops. The mount was workable for the
new C102, but just barely.
Nevertheless, thanks to its consistent optical quality, the
C102 OTA just kept on trucking year after year, hopping on different mounts as time
passed and occasionally undergoing minor styling revisions, but staying good,
very good. Whether on one of the NexStar goto mounts, or, as today, on
Celestron’s non-goto CG4, “C102” spells “Celestron” every bit as much as “C8”
does. One nice change to the Chinese C102 a few years after its introduction
was that the original 1.25-inch rack and pinion was replaced by a 2-inch job.
Want a C102 today? Celestron’s CG4 – C102 combo is nicely
priced at $499.95—the scope is not over-mounted on the CG4 GEM, but the mount
is sufficient for it. What’s truly amazing, however, are the periodic C102 OTA
sales you can find, especially from OPT, Oceanside Photo and Telescope in
Cally-for-nye-ay. Right now, you can get an OTA for 170 dineros, and last year
they were selling the scopes for the astounding price of 50 bucks. At any of the above prices, the C102 is an
incredible buy.
Not that your old Uncle necessarily believed that when Pat
dropped the C102 off at the New Manse. Oh, I remembered how he had raved
about another 102 he’d owned years ago, how it literally tore up the dark night sky at the Chiefland Astronomy Village one
cold winter night in 2001 (the year the Winter Star Party was canceled and many
WSP refugees wound up at the CAV). Still, I wasn’t quite convinced. An achromat, a 4-inch at f/10?
To get the cursed color purple down low on a 4-inch, you
have to go to f/15 or f/16, like those long, long Unitrons. On the other hand,
I recalled having had a heck of a lot of fun with my old Short Tube 80,
Woodstock, and that 80mm f/5
certainly wasn’t lacking in chromatic aberration.
The bottom line on excess color? It bothers some people more than others. Me? I am not overly
troubled by it, whether it’s around bright stars or turning lunar shadows a
deep purple instead of inky black. The question would not be whether it would disturb me, but how much—if any—sharpness
it would steal from the C102’s images. That is the real problem with chromatic
aberration. At high levels, it blurs the image. Howsomeever, I well remembered
one cold night in 1999 when I watched a triple shadow transit on Jupiter with
Woodstock. I was amazed at how sharp the planet was. So, I was willing to give
the C102 a tryout.
What with all that was involved in getting settled in the
New Chaos Manor South, it took some time for me to get around to giving Miss
Betty a tryout. “Betty?” I don’t name my telescopes, y’all. Oh, they all have names, but I don’t give them names, they tell me their names, eventually. It took
a while but my C102 finally whispered that she is to be called “Betty.” Which makes sense. My fluorite William Optic refractor is the classy Veronica (Lodge), so this one is naturally the more down-to-Earth girl next door, Betty (Cooper), Archie fans.
Anyhoo, what prompted me to give Betty a go was that I had
come to favor refractors for my quick backyard observing. I can waltz one out
of the sunroom and onto the deck in 15-seconds flat. Not that Miss Cooper didn’t
have competition there. Miss Dorothy’s Explore
Scientific AR102 does a fine job and delivers nice, wide fields. Unk got to
thinking, however, that it might be nice to have a little less color than presented by Miss D’s f/6.5
telescope. Of course there's Veronica, who at about f/7 presents a wide swath of sky, but I thought 20mm more aperture might be a good thing for visual work.
To cut to the chase, for visual work Betty does great...but... There's less spurious color than in the ES refractor, but there's really not a huge difference to my eyes. Also, while the C102 threw up a dadgum impressive star test,
the 80mm APO, Veronica, does just a smidge better, and despite her smaller aperture doesn’t fall
far behind in visual performance. If she does
at all.
There’s more to a scope than just performance, though; there was
something about the C102’s long tube towering above me. It was if at least some
of those daydreams I dreamed while mooning over the old Unitron catalog as a
sprout were finally coming true. Color? There’s purple, but it is bearable.
I did quite a bit of touring of the bright deep sky objects
with the C102 on the moonless nights that followed, but there’s only so many
times you can look at M2, M13, M92, and the rest of the showpiece gang before
getting a mite bored. Oh, the summer and fall Messiers were as beautiful this
autumn, my 50th autumn observing them, as they ever were, but no matter how pretty
they looked in my “new” telescope, I wanted some variety in the backyard. What
else could I do with Betty? What would she be good at?
One afternoon I was shelving some books that had come over
from the old Chaos Manor South in a box, and ran across a real blast from the
past, Herbert Bernhard, Dorothy Bennett, and Hugh Rice’s New Handbook of the Heavens (1954). It was one of my favorites in
the hallowed day, not only because of its clear prose and the observing lists
at the ends of its chapters, but because Edmund shipped a copy with every telescope they sold.
The book was missing from the box of my first real scope, my used Edmund Palomar Junior, but the following summer I was able to get a copy at the Miami Space Transit Planetarium's gift shop and meet Jack Horkheimer in the bargain. I had no inkling Jack would shortly become famous as the Star Hustler, but one thing I did know: if Edmund Scientific
included the book with their telescopes, it must
be a dang good one.
The New Handbook is actually a follow-on to the original Handbook of the Heavens (1935), but
while it is an update, there is no question it is still about the old amateur astronomy. An amateur
astronomy where the deep sky took a decided backseat to other pursuits. Take a look at the Handbook’s table of contents and you’ll
find you have to scan down almost to the bottom to come to the “Star Clusters
and Nebulae” chapter.
The authors do do a good job describing what there is to
see of the deep sky with a small telescope, and at the end of the chapter,
there’s an outstanding list of 60 of the best of the best DSOs for little
scopes. But most of the
Handbook’s space is devoted to the things most amateurs of 1950s - 1960s
observed more often than even the bright Messiers, however. The emphasis in the book is on the Moon, the planets, and double and variable stars.
Why did amateur astronomers tend to restrict themselves to
those subjects when a mere 4-inch refractor or a 6-inch reflector will do one
heck of a job on the deep sky? Because most amateurs, even in the 1960s, didn’t
have a 4-inch refractor or a 6-inch
reflector, with the refractor being a particularly tough nut to crack for most
of us. Edmund Scientific’s reasonably priced 4-inch refractor, for example, was
$247.00 (their 6-inch Newtonian was 50 bucks less). Depending on how you calculate such things, that
is equivalent to at least $1370.00
today. A high-toned Japanese-made refractor like a Unitron? Don’t even ask, Bubba, don’t even
ask.
Because of the way-out prices for store-bought scopes, amateurs
in the 1960s, and not just kids, often made do with 2.4-inch refractors and
3-inch reflectors. Yeah, you’d think from what the old timers down to the club say
that everybody back then was grinding and polishing 6-inch mirrors, but that was
most assuredly not the case. Then as now, most of us, and especially us
sprouts, were amateur telescope buyers,
not amateur telescope makers. Accordingly,
astronomy authors tended to restrict themselves to objects within range of our small
scopes: double stars, the planets, the
Moon, and the brightest deep sky wonders.
Its focus on the bright stuff made the New Handbook of the Heavens, Unk thought, just about the perfect
guide to what I would enjoy with my 4-inch lens-scope from my light polluted
backyard (limiting magnitude at the zenith not much better than 5 on a good
night). There was also just something romantic about pursuing the old amateur astronomy,
the amateur astronomy of Patrick Moore in his heyday, with a long-tubed
refractor on chilly (well, for down here) fall nights. I’d already done a quick
survey of bright DSOs; it was now double star time.
I’ve never been the world’s most committed double star observer. I’ve blown hot and cold on binaries
and multiple stars over the last half century. Obviously, my contributions to
and support of The Journal of Double Star Observations are signs that these stars are
an important interest of mine; I’m just a-saying you shouldn’t imagine I go
pair-hunting every dadgum night. I still and always will love doubles, however,
and was happy to have an excuse to look at the best of the best with Shelley.
Before I could do that, however, I needed to rectify the
finder stichy-ation. As delivered, Miss Betty was equipped with a
pretty but too-small 30mm finder. I immediately replaced that with a red dot
job, which, even in our gray skies, was sufficient for locating the brightest
Messiers. To run down medium bright doubles, though, much less dimmer ones?
Uh-uh. Luckily I had a 50mm Orion RACI finder sitting unloved in my shop. It
was in a Synta mount and would slide right onto Shelley. I am not a huge fan of right angle finders,
correct image or no, but I figgered the RACI would at least be superior to the
alternatives.
So it was that I began a survey of Double Star Gooduns on a
chilly (40s, y’all) November evening. The sky wasn’t perfect; haze was moving
in ahead of a front and one look at Vega showed the seeing was at least
semi-punk. But I’d been down in the dumps—for no good reason, really—all
afternoon and figgered an hour or two under the stars would help, even if
conditions weren’t all they ort-ta be. While I used the New Handbook as a
general guide to what would be fun look at, I didn’t try to decipher its small
text under a red light. Instead, I loaded up the Astronomical League Double Star List on SkyTools
3 on my Toshiba laptop.
One of the loveliest things about a refractor? Just a few
minutes acclimating to outdoor temperatures on this cool night and one is ready
to rock. I’d mastered the fine art of moving Betty from the sunroom where she
lives out onto the deck without removing her big tube from her SkyWatcher AZ-4
alt-azimuth mount, and in five minutes I was ready to start looking and she was
ready for me to start looking…
Beta Cygni, Albireo
“Two tiny points of light—one rich orange, the other a deep
blue—placed close together in the telescopic field—such is the appearance of
Albireo…the concealed beauties of many similar stellar objects lie unsuspected
until discovered in the telescope.” So says the vaunted New Handbook, and I
agree—do I ever. I love Albireo, the
blue and gold “Cub Scout Double,” though I don’t look at it often. I mostly
just show it off on public outreach nights,
taking a quick glance at it to make sure it’s centered and focused.
On this night, I spent a little time with Beta Cygni. At my finding
power, 67x, with the 16mm 100-degree AFOV Happy Hand Grenade eyepiece, the view
was scrumptious, and not just because of the deep and vibrant colors as
described in the Handbook. What made Albireo doubly outstanding was the tiny, perfect appearance stars tend to
assume in a good refractor. I stared for at least 15-minutes despite being
hunched over at the eyepiece—even at full extension, the AZ-4 tripod is not
really tall enough for a 4-inch f/10.
Alpha Ursae Minoris,
Polaris
As is often the case when I’m chasing double stars, Polaris
was one of the first pairs of the evening. It’s a good test of conditions. As
usual, it was easy but not that easy.
The secondary was visible, but I did have to look for it in the seeing, which
was definitely tending to “poor.” It soon showed itself as a little white spark
beside the strongly yellowish primary. Since the separation between the two is 18.4”,
you’d think resolving Polaris would be like shooting dadgum fish in a barrel,
but it is not so. I could see the comes
with the 16mm eyepiece, but I needed the 7mm to make it really stand out.
Polaris is tough because of the difference in magnitudes between its primary
and secondary which are, respectively, at magnitudes 2.0 and 9.1.
Epsilon 1 and 2 Lyrae,
the Double Double
Since I was in the area, figgered I might as well check in
on the famous Double Double, Epsilon 1 and 2 Lyare. Epsilon 1 is at magnitude
4.7 and Epsilon 2 at magnitude 5.1 and they are separated by a huge 208”,
hardly a challenge—the split was trivially easy in the 50mm finder. That ain’t
the challenge, though, the challenge is that each of these two stars is itself a close double.
Epsilon 1 Lyrae is composed of a magnitude 4.7 primary and
magnitude 6.2 secondary separated by 2.6”. Not usually a problem for medium
aperture scopes at medium magnifications on nights of good seeing, but more
than close enough when, as on this evening, the air doesn’t want to hold still.
Epsilon 2 is a magnitude 5.1 and 5.5 pair, and is a wee bit closer together at
2.3”. Again, not a huge challenge, but enough of a challenge when the seeing
sucks. What helps is that both pairs’ stars are fairly close to each other in
magnitude.
Anyhow, despite the relatively lousy atmospheric conditions,
Epsilon 1 and Epsilon 2 were split at 143x in Betty with my 7mm William
Optics Uwan eyepiece. I could see that the stars were elongated at 67x, but
only barely. Only when the seeing would
change and they’d briefly stop shimmering and dancing around.
Gamma 1 Andromedae,
Almaak
Almaak is another one of the very best doubles. The “end”
star in Andromeda’s eastern chain of stars is a nice, easy split at 9.0”, which
also puts the primary and the companion close enough together that the pair
really looks like a double star at medium powers. The primary is a beautiful
deep golden color and shines brightly at magnitude 2.0. It is made even more
lovely by the contrast provided by the secondary, which stands out well at magnitude
5.0 and has a light blue-green tint.
Despite Almaak being over the house and in the extra poor
seeing caused by heat rising from the roof, Betty did a fine job. At 67x I
coulda drove a truck between primary and secondary. Other observations? Mainly
that the secondary star looked bluer to me than it does in my SCTs. Whether
that is due to the smaller aperture of the refractor, or to the fact that it is a refractor, I don’t know, but the
difference was noticeable.
Eta Persei, Miram
Miram is a famous double star, but not one that’s really a
showpiece in this old boy’s opinion. The separation, 28.9”, makes it an easy
but relatively wide one, and at magnitude 7.9, the secondary star seems somewhat
lackluster. The mag 3.8 primary was easy to spot, even in the eastern horizon
light dome from consarned Airport Boulevard, and is an obvious deep
gold-orange. The secondary? From the first glance, the secondary seemed a pale
blue. Not the “very blue” the Handbook claims, but blue, not white as it’s
appeared in my C8.
Since I was in the neighborhood, I bopped over to the west
to have a look at the Double Cluster, just a little less than four and a half degrees
away. Despite still being in the heavy light pollution and in increasing haze,
the two companion open clusters were wondrously beautiful in the Happy Hand
Grenade. There is just no way to make ‘em look bad, y’all. But, as I watched,
they began to do a fade out. The occasional bands of thick haze were morphing
into genuine clouds and it was time to throw the Big Switch.
Throwing that Big Switch took all of maybe two minutes.
Objective cap on the scope, pick her up, and back into the house we went in
nuttin’ flat. Grabbed the eyepieces off the patio table and we was done. I
didn’t have to pack up the Toshiba, since I’d set up the laptop in the sunroom
so I could duck inside and warm my old bones when scoping out the next target
star with SkyTools.
Yeah, double stars were great in the refractor, muchachos, but
that is hardly all she can do. In addition to a surprisingly good job on the
deep sky, she has made a believer out of me when it comes to the Moon, and I
originally intended to clue y’all in as to how Luna looked in the achromat.
Unfortunately, I see it is time for me and my girl, Betty, to run along before we wear
out our welcome this Sunday morning. You will hear more about our adventures
soon, and not just on the Moon, but on the planets—King Jupe is on his way back
into the evening sky, and I am curious what my new friend of a telescope will
accomplish there.
Next Time: Unk's Astroware Top 10…
Sunday, November 16, 2014
Being a Joiner
What is something your garrulous old Uncle hasn't talked
about in quite a spell, muchachos? Astronomy
clubs. As those of y’all who've been here a while know, Unk is a big supporter
of organized amateur astronomy. What you sprouts raised in the Internet age may
not know, however, is there are still mucho
reasons for you to belong to a non-virtual club.
“But Unk, but Unk, the Cloudy Nights BBS (or Astromart or
the Astronomy Forums or Ice in Space) is just like belonging to a club, a club with
thousands of members. One whose meeting is in session 24/7. Why would I want to
join-up with that astro-club that meets in the smelly old backroom of Wally’s
Filling Station?” Well, Skeezix, maybe the place to start in cluing you in as to
the reasons for holding your nose and heading down to Wally’s is to give a
quick rundown of my five decades of experience with clubs.
Looking back, I reckon I’ve been a member of…oh…four-five
astronomy clubs in my five decades of observing. That began with my first club,
which we members didn’t think was a real astronomy club at all, but was—was it ever. I’m talking about the legendary Backyard Astronomy Society formed by
Unk and a few of his nerdy buddies in our junior high years.
We BASers occasionally had delusions of grandeur, like the
time we talked about mailing that holy of holies, Sky & Telescope, a detailed report on our activities for use in
the old “Amateur Astronomers” column. We also planned to send in a blurb to the
newspaper, The Possum Swamp Register and Birdcage
Liner, making our presence and meeting schedule known to the community at
large. Soon we’d have a hundred members. Then
we’d be a real club.
We never quite got up the gumption to do either of those
things, or even post a flier at the public library. What we did do was get together, mostly in the
summertime, but on weekends throughout the school year, too, to observe from members’
backyards and vacant lots or just hang out and talk astronomy and analyze
the latest issue of Sky & Telescope
(and the latest issue of the Fantastic Four’s comic magazine, too). Our star
parties were somewhat constrained by the need to enlist our mamas and daddies
for transport duty. Purty dern hard to tote a Palomar Junior around on a
bicycle. Nevertheless, we did a lot of observing over the four years the BAS
was active.
Me and my good buddies Wayne Lee and Lamar formed the core
group, which occasionally expanded to seven or eight “astronomers.” That was
purty much the height, and as tenth grade began, the BAS star parties became
fewer and farther between as our ranks shrunk as parents moved away in the wake
of Brookley Air Force Base’s closure. There was also considerable natural
attrition as girls and cars began to work their way into the consciousnesses of
even us nerds. Till that happened, though, what
fun we had!
Assembled in somebody’s backyard, we would usually have at
least four scopes cranking. My Pal Junior was the aperture king till Lamar and
his daddy fabricated their very own 6-inch from a mirror kit they ordered from Jaegers. At first I was miffed at not
having the big gun anymore, but I got over that. I could now observe with a
six-inch reflector regularly, and toward the end of the BAS’ existence, Lamar and his
old man even showed me the ropes of mirror making.
It didn’t matter if we were observing with the Pal and the
Big Six, or just a couple of 60mm refractors and Unk’s old 3-inch Tasco Newt,
which was what I had when the BAS began. What mattered was that we were observing together and that was more
fun and more productive than observing alone.
Group observing was more productive for me not just because
I didn’t have to fear the depredations of the dadgum Wolfman and the UFOnauts when I was with my friends. It was because we helped each other. Like the night I
went after the Blinking Planetary in Cygnus for the first time. The
books said it was bright and obvious, but danged if I could find it. If I had
been by myself, I’d just have given up and moved on. But Wayne Lee had looked
at it before and showed me how to track it down. Our individual skills and
knowledge might have been pitiful, but by working together we saw
a heck of a lot and learned a heck of a lot.
And so it went till the good ol’ BAS slowly faded out of
existence. It was the greatest astronomy club I ever belonged to, just
like maybe the Palomar Junior was maybe the greatest telescope I ever owned. I’ve had
“better” scopes and been a member of “better” clubs over the intervening five
decades, but nothing has ever quite equaled or ever will equal those long-ago summer nights in the
backyard with my Pal and my pals.
After the BAS dissolved completely, probably late in our junior year of
high school, Unk was clubless for a long time. I pushed on observing, of
course, but maybe not as frequently or with as much of the old enthusiasm. I missed having somebody to talk shop with astronomy-wise. Most of
all, I missed observing with my friends. Alas, there was no astronomy club at
either of the universities I attended.
I didn’t join my first (adult) club till the mid 1970s when
I was in the Air Force and stationed in Little Rock, Arkansas. There was a
vibrant club there, and on those rather infrequent occasions when I could attend a meeting, it was fun if not nearly as much fun as the
BAS. Several moves and about about a decade later, I wound up at the vaunted
Possum Swamp Astronomical Society, whose ranks I was part of for over twenty
years.
Whether the BAS or the PSAS, the joys of and motivations for
club membership have always been the same for me: camaraderie and the sharing
of knowledge and skills. And, in the average adult club, there are some pluses
that go beyond even those things.
One biggie for many boys and girls is that just about every
astronomy club worth its salt has a dark site for group observing. In the BAS
years, that wasn't important. Even if we’d had a dark site and a way to get to
and from it, we didn’t need it. Our suburban skies were almost as good as the
average suburban-country transition zone club site today. But with the growth
of all them subdivisions and shopping malls from the 60s till now, today most
of us need something better than the backyard for our serious work.
If you have a nice little piece of land out in the dark
countryside, bully for you. Few of us do. What makes a club important here is
that it is way easier to find a dark
site as a group. With a sizable membership, it’s likely somebody knows somebody with dark country land. It’s also easier to get permission to use a site
as an organized group than as an individual—unless you have a close friend with
a country place, which, again, most of us don’t. Observing as a group at a dark
site is also good for security's sake. Not because of the Mothman or the Skunk
Ape (though all these years later, Unk can still get nervous over things like that), but because of the very real presence of bad guys in the
hinterlands due to the meth trade.
Another reason to belong to a club, and an important one
these days, is that it gives you an organization and sometimes a venue for
doing public outreach. Yeah, I know that
isn't everybody’s cup of tea, but most of us realize the importance of bringing
new folks into our slightly graying avocation. NO, I don’t think amateur
astronomy is doomed to disappear as us Baby Boomers do the big chill, but there
is no question it’s a Good Thing to bring new folks into the hobby. Not
just kids, but groups that have traditionally been under-served by us—women and
minorities.
Just as when searching for a dark site, outreach is easier
to do in the context of an organized group. The schools, for example, might be
happy enough to have the help of a lone amateur, but a group of ten, twenty, or
more amateur astronomers will be better. A single
amateur can make a difference, but a group, showing the sky to a hundred or a
thousand kids and parents will make a bigger difference.
Finally, there is that comradery factor. Yeah, it is cool to
be able to log onto Astromart and participate in the forums, but I believe it
is still more fun to interact with your fellow amateurs in person. And if you
need help, a non-virtual club is a better way to get it. Folks can have
Newtonian collimation, for example, explained to them a million times on the
dadgum Cloudy Nights and still not get it, but will learn it easily from one
hands-on session down to the club.
There are also the ineffables, the things not strictly
related to the astronomy club that nevertheless enhance your amateur astronomy
experience. A couple of clubs I’ve belonged to and visited have held a Meeting after
the Meeting. Once the formalities wind up, you and your mates adjourn to the
nearby bar or—maybe even better—one of the family-oriented grills and bars like
Applebee’s or TGI Friday’s to have some drinks and snacks and talk astronomy and
who-knows-what-else for a couple of hours. To tell you the truth, often these ale-fueled bull sessions have been more interesting and productive than a dry-as-the-Sahara club business meeting.
Possibly the best thing about belonging to a club, though? Again,
you make friends, friends with the
same magnificent obsession for the Great Out There you have. Sometimes, lifelong friends. After a
couple of meetings, you’ll find yourself giving one of your fellow club members
a ring to ask about that new eyepiece. Your conversations will
soon range farther afield, beyond amateur astronomy, and you’ll start spending time with your friend outside
meetings. I know that this one thing has made astronomy club membership, which
has its headaches as well as joys, one of the better parts of my life.
Yes, there are headaches.
Like anything else, life in an astronomy club is not perfect. To start
with, every club I’ve belonged to has had a member or three of the “off the
beaten path” persuasion. These are the people who attend every single meeting
without fail, but never observe and will never own a telescope. Many of them also
have an odd take on the science of astronomy, like a former PSAS member, Junie Moon, who went a couple of years before she determined we were not actually an ASTROLOGY club,
“Them dadgum people never would tell me my horoscope!”
I used to wonder why people who had no interest in
practicing astronomy would go to astronomy club meetings month after month
after month. In fact, it used to bother the heck out of me. No more. I finally
realized an astronomy club is serving some kind of need for these people, and
that they are indeed practicing and enjoying our avocation in their own way. They sometimes make me scratch my head, but they
don’t bother me anymore.
In fact, some of these “armchair astronomers,” if we may
call them that, can be real assets. Linda Sue will never be found lugging a
scope onto a dark observing field, even if she happens to own one. She can’t help
you with picking a new eyepiece, either. But she has a talent for organization
and can get the club’s Christmas banquet on the rails right away. Cousin Ezra
over there believes Immanuel Velikovsky
was 100% correct about them colliding worlds, but he is also a skilled
machinist who can make a no-longer-produced part for your telescope mount in a
right quick hurry. And so it goes. Don’t underestimate someone’s worth to your
club just because they haven’t memorized Suiter's book on star testing.
No matter who contributes what, you will eventually find
your club entering the doldrums. I am convinced that happens to all clubs. Leastways it’s happened to
all those I’ve belonged to and all those I’ve heard tell of. Even big, wealthy
clubs in large cities have periods when they are more active and periods when
they are less active. Our PSAS has ascended to highs of 15 or
even 20 active members (right good for a small city that ain’t exactly scientifically
oriented) and descended to lows of four or five lonely souls.
I used to fear a crisis was upon us during these declines,
but I’ve come to believe that is just the natural ebb and flow of a club. There is always a
core group that keeps a club alive year after year, but other members come and
go. Some move away. Others find astronomy ain’t as much fun as they thought it
would be (usually, these folks have discovered some work is involved). In other
cases, especially, unfortunately, with that much to be desired twenty – thirty
something demographic, family/kid commitments get in the way of amateur
astronomy for a while.
While some of these dips are unavoidable, you don’t do
yourself any favors when it comes to retaining members by allowing the club to
get into a rut. An example? Years ago,
the PSAS got into just such a rut. A deep one. Membership was down. Meetings
were a real bore. Nobody outside the poor put-upon officers contributed
anything to them. The rank and file sat like zombies listening to the
Treasurer’s Report and hoping and expecting to be entertained. My friend and
fellow member, Marvin Uphaus, had an idea:
we’d have a member do a presentation each month, a talk on one of the
constellations currently well placed for observing.
“Marvin’s constellations,” as we came to call the monthly
presentations after Marv's untimely death, worked great. Every month a
different member would be called upon to present a constellation. At first, we
had to use a bit of gentle persuasion, but before long, we all got into the swing
of things and pitched in. Every member did something once in a while. Nobody
got back into the passive, “entertain me” mode.
All was well for a long spell. Too long a spell. I don't know how long Marvin’s Constellations
continued, or how many fracking times we went ‘round the sky pictures visible
from 30-degrees north, but it was a bunch. Years and years worth. Till,
finally, one evening a presenter, who was as bored as his audience was (had to be, I hope), droned
on and on and on. “This constellation has seventeen prominent double stars; I
will now recite their magnitudes and separations.” Unk suddenly began to feel
like Popeye the freaking Sailor Man: “I’ve
had all I can stand; I can’t stand no
more!”
When the evening’s constellation finally wrapped up, I
allowed as how maybe, just maybe, we
should broaden up the presentations. Certainly, it would be OK for someone
excited about a constellation and its stars and deep sky objects to do a talk
on it. But I thought that should no longer be required. Any subject would be
welcome as long as it stuck with amateur
astronomy, or at least the science of astronomy (we once had an unpleasant episode with a
Creationist who tried to convince us Dinosaurs and men coexisted, just like
on the doggone Flintstones).
Everybody seemed relieved that we’d no longer be yoked to
the constellations. We may revisit Marvin’s Constellations it in the future,
however. It was a good idea; we just fell asleep at the switch with it. Too
much of the same-old, same-old is, well, too much. After years of the
constellations, we were beginning to drive off members out of sheer boredom rather
than involve them.
Other than letting your meetings get into a rut, what is
bad? Endless Treasurers’ Reports and microscopically detailed minutes from the
previous meeting. Yes, you need to give due attention to those things, but
don’t make it into Chinese water torture: “Following the call for new
business, Joe Schmoe excused himself to visit the little astronomers’ room,
Judy Blue Eyes blew her nose, and Elmer dropped his pencil…then…” Use some common sense, y’all.
One thing that will destroy any club in short order? Feudin’
and fussin’. There will always be disagreements about the club and its
direction. Disagreements between members, between officers, and between
officers and members. It is up to your club’s leadership not to let them get
out of hand.
When controversy arises, like the ever popular, “What the
hail do we get out of the dadgum Astronomical League; why should we send ‘em
all that money?” and threatens to escalate into something more than discussion,
the person running the meeting has to keep the lid on. And do that without
appearing to dismiss either side. One way of doing so is to form a committee to
study and report on the issue, taking pains to see both sides are represented
by clear and cool-headed members.
I’ve seen all too many clubs, large and small,
fail because nobody knew how to keep the peace. However, I'll also say that if there aren't disagreements every once in a while, something is likely very wrong. Often these occasional fusses are simply a sign the members are passionate about the club.
Once you’ve got a good club going, believe you me,
muchachos, you will want to keep it
going. You’ll discover the club has become much more than a monthly
ritual. Your fellow members have begun to seem like, yeah, family. Not a club member? Time’s a
wasting: go rat-cheer
and purty soon you’ll find yourself arguing about the fricking-fracking Astronomical League and the price of a
good telescope with the rest of us—and having one hell of a time doing it.
Postscript
It's amazing, muchachos, how things can change--how much they can change--in a relatively few years. When it comes to my astronomy club, that change began not long after this somewhat effusive article (which was maybe in part me whistling past the graveyard) was written. As 2014 rolled on, Dorothy and I were still attending every meeting. However, we'd invariably stop at the Applebee's around the corner for dinner and drinks first.
I finally had to admit the allure of Applebee's OK food and good drinks beforehand was the only thing that got me to the meetings anymore--I needed to anesthetize myself good, first. We soon began to find reasons why we just couldn't go to the monthly meeting, attended fewer and fewer, and eventually stopped going altogether. I have not been back in years.
What changed? I think my annoyance over the monthly "Marvin's Constellations" business was the beginning. Meetings were boring; I wasn't getting a thing out of them (and I know Marvin would have felt the same way if he'd still been with us). Month after month of doing things as a rote exercise had finally got to me, and I had reached my infamous "I Have Had Enough" stage (something I inherited from Mama).
The vaunted good old days really were good. |
If there's one reason I'm sorry to not be an astronomy club member anymore, it's because I no longer have a good way to contribute to astronomy outreach to the general public. On the other hand, teaching astronomy to several sections of undergraduates every semester kind of fulfills that duty.
What will I miss? The club as it was in the mid 1990s. What fun we had! Things change, of course, that is the unalterable way of things on this rock, but that does not mean I have to like it. However, while those days are gone and are not coming back, I have many good memories, and I guess that will have to be enough.

A Deep South Saturday: Project Scotty Night 2
Dawn Sunday... |
I am not telling y’all anything you don't already know when
I say the weather in the formerly sunny South and much of the rest of the good
old U.S. of A. ain’t been very astronomy friendly the last few years. Of late,
it’s been unusual for us to get even two clear nights over the four (now five)
night run of the Deep South Regional
Star Gaze. This year was different, Muchachos.
As you learned last week, ol’ Unk had a great Wednesday
night, part of Thursday, and a spectacular Friday. The folks who’d been
onsite since Tuesday had had yet another whole evening of deep sky craziness.
As you also heard last week, that created a problem for your old Uncle. What would I do with a Saturday night that was also going to be a good one?
My observing list was finis.
I could always take one more tour of the summer/fall
showpieces, you know, M13, M27, M15, M31, yadda-yadda-yadda. But that didn’t
seem too productive a way to spend one of our increasingly rare dark and clear
nights. Well, OK. What did I have going on when it came to visual observing projects?
There was my Messier Album series,
but that required the services of a my 5-inch ETX-125, Charity Hope Valentine, and I’d decided—maybe
foolishly—against bringing her to DSRSG 2014.
That left only one recent and incomplete visual project, Project Scotty, my (proposed) quest to (maybe) observe all the
objects in Deep Sky Wonders, the book
Steve O’Meara compiled from Walter Scott Houston’s legendary Sky & Telescope column. Seemed like that
might do the trick for Saturday. I hadn’t put an aperture limit on the scopes
I’d use for Project Scotty, and I’d hardly begun it, being only five objects
into a list that contained nearly 500 DSOs.
Breakfast: the biscuits were good, anyhow... |
Before I could get Project Scotty going again, however, I
had to get through a long Saturday. We sure lucked out with our choice of dates
weather-wise this time, but the days do go a lot quicker when the star party falls
after the end of the dadgum Daylight Savings Time. Especially considering I was
up right early Saturday, in plenty of time to catch another breakfast where I
had to use a magnifying glass to find my scrambled eggs. I nearly had one of my infamous meltdowns (wherein I assume the persona of a small, emotionally disturbed child), right in the dining hall!
One thing that would make the day go faster was that
I had a second talk scheduled on Saturday afternoon. The first, “Things that Go ‘Bump’ in the Night Sky:
Observing the STRANGE Stuff,” which I’d first given at this year’s Almost Heaven Star Party, had been a hit Friday
afternoon. The second would be a gear-switcher, a program heavy on audience
participation, a discussion of smart phones and tablets in amateur astronomy.
A bit before noon, Miss Dorothy and I walked over to the
Feliciana Retreat Center’s auditorium, Barton Hall, not far from the
observing field. We were just in time to catch Steve Edmiston, who preceded me with
his presentation about making the screens of Android devices
astronomy-friendly. That was a good thing. Not just because Steve’s talk was an
excellent one, but because I was able to call on him during my presentation
when questions arose concerning Android phones and tablets—Unk is most familiar
with the iOS (iPhone, iPad) widgets. Anyhow, my Saturday talk went as well as
the Friday one—purty good, that is.
After Barry Simon’s “The Fall Night Sky,” outlining the
best objects to view and image during this transitional time of the year, D.
and I headed back to the field to take down our tailgating canopy. Normally, we
leave it up for the final night of a star party, but I thought it would be best
to take it down on the last afternoon this time. I had a couple of stacks of
astronomy student papers among other things awaiting my attention at home, and I wanted to skedaddle
as soon after breakfast as possible.
If we tore down the EZ Up Saturday afternoon, not only would
we not have to spend time cramming it back in its case Sunday morning, we wouldn’t
have to wait around for the Sun to dry it first (the dew was heavy every night).
Or, worse, have to unpack it again once we got home to let it dry out. I
originally thought I might pack up the observing table, too, but decided I
wanted to use the laptop Saturday night after all. The Toshiba would be fine on the table under its little corrugated plastic shelter without the protection
of a canopy.
Packing up the canopy Saturday afternoon... |
When we had the EZ Up in its case (which was not exactly fun under the blistering Louisiana Sun) and in the truck, it was it
was door prize time again. As usual, Unk was coming into the last prize
giveaway empty-handed. Dorothy had won a nice, small red light Thursday (which
she promptly gave away to a novice who’d arrived without a red flashlight), but
I hadn’t got nuttin'. Amazingly, my name was called, but by that time, prize
pickings was slim, and I responded “pass,” to allow somebody else to get one of
the items that remained. I wouldn’t have minded winning one of the big prizes
this year, but I am past the stage where I need yet another small gadget--or astro-gear of any kind, really.
That brought us to supper, which was, as mentioned last time, a huge bring-down. I’d been
craving the FRC’s delicious smoked brisket, a final night tradition for the
past five years. Nope. Instead we were served frozen
(tasted that way, anyhow) hamburger patties on untoasted buns with bags of Lays chips on the side. Oh, it was passable, I guess. Even the fixins were slim, not even any onions for gosh sakes, and certainly
not quite what your backwoods epicure of an Uncle had in mind.
What comes after supper on long Daylight Savings Time
afternoons? Why a nap, of course. I
grabbed my Nook and headed to our Lodge room to continue Triplanetary. Just as Doc Smith’s evil Eddorians and benevolent
Arisians began slugging it out, Unk dropped off into a slumber which would
likely have continued well past the time I needed to be back on the field if
Miss D. hadn’t awakened me with “Getting
dark, Rod!”
On the observing field, the routine was much the same as it
had been. Uncover the scope, connect the Sky Commander DSCs to the laptop,
align on Polaris and Fomalhaut, light off SkyTools
3 and begin touring the Universe. The star party was the first time I’d
been able to try the combo of ST3 and the Sky Commanders under a dark sky, and I
was pleased at how well they worked together. I found I occasionally had to mash the “Push-to” button on SkyTools more than once to ensure the DSCs received the object data, but that didn't cause major heartburn. It
sure was nice to have SkyTools 3’s
huge object database at the Sky Commanders’ disposal.
Last door prize giveaway... |
Not that I’d need ST3’s enormous selection of catalogs Saturday
night. The Scottys on this evening's agenda would tend to the bright and spectacular.
I always like to revel in Cool Stuff on the last night. I also didn’t
intend to cover a huge amount of ground. One of the few rules of Project Scotty
is that each object gets plenty of eyepiece time. I figgered that, with
occasional breaks, maybe ten DSOs would be enough. That would also allow me to
proceed in a fashion suited to the fact that I was weary after the
preceding nights of my deep sky tear.
In addition to setting up telescope and computer, I hunted
up the little am/fm radio I’d bought at freaking Wally World. I hoped to pick
up Game 3 of the World Series out on the observing field, and with a little
twiddling I found an FM station carrying the Royals – Giants duel. The
reception was lousy—north Louisiana is a radio wasteland and WWL in New
Orleans didn't have the game on—but it was good enough for me to keep
occasional tabs on the Giants as the evening progressed.
Hokay, what would be first? M2, the grand globular in Aquarius, was high and in the clear and
and one of my all time faves. In Deep Sky
Wonders, Scotty’s discussion of M2 begins with its naked eye visibility.
Mr. Houston spotted it, he says, from the bayous of Louisiana, but he must have
had darker and drier Louisiana skies than I did. On Saturday, the southern sky at
Feliciana was dark gray and not likely to give up globs to Unk’s aged eyes.
In Old Betsy, M2 appeared fully resolved right to its small,
bright core. One other thing I noted, and which I’ve noticed before, is that
the cluster seems to me to have a strong bluish cast. Maybe coincidentally, Scotty
mentions author Glyn Jones reported seeing a greenish-blue glow around the cluster. I didn’t see any
such thing, but the faint blue tint of M2 itself was striking.
Next up was another glob, Pegasus’ M15, to which Scotty devotes considerable space. Understandably,
since, as he says, “The view of M15 is impressive with anything from binoculars
to the largest telescope.” It never fails to blow me away, and certainly did
this time. In the 8mm Ethos (187x) the center of M15’s intensely bright core was
nearly star-like. But that wasn’t the big draw; that was how far out its halo
of tiny, tiny stars extended. It easily filled the field of the 100-degree
Ethos 8mm.
To Monster or not to Monster? |
Naturally, Scotty mentions M15’s notoriously tiny and dim
planetary nebula, Pease 1. He
doesn’t report seeing it himself, but does say a couple of observers he knows conquered
it by “blinking” it with an OIII filter, repeatedly placing an OIII filter between
eye and eyepiece and removing it in hopes of making the planetary alternately appear and
disappear, making it more obvious. I’ve tried that and every other
trick in the book over the years, including with ATM Pat Rochford’s old 24-inch
Dobsonian at insanely high powers, but I’ve never even seen a hint of Pease 1.
Mr. Houston’s discussion of M39 starts out purty much the same as you’ll read anywhere; it’s a
rather sparse cluster in Cygnus enclosed in a triangle of bright stars. But he
doesn't leave it at the easy and obvious. He mentions a curious dark streak
he’s noticed, a dark nebula 5-degrees southwest of the cluster. I’ve never seen
a dark nebula in the area, and I am doubtful of ever seeing it. Scotty says following this dark lane leads you to the Cocoon Nebula, which he implies is more prominent. I know the Cocoon
routinely gives me fits, so I don’t expect I’ll ever see Scotty’s Streak.
Not that I didn’t have a nice look at M39, which I always
find to be prettier than I remember. At half a degree across, this Cygnus open
cluster is a job for the 35mm Panoptic (42X). Its equilateral triangle of
bright stars encloses a medium-rich group of similarly bright stars, about 20. These
are set against a background of dimmer stars. There is an attractive double
star near the center of the triangle.
That his dark nebula “leads” to the Cocoon Nebula is the
only mention IC 5146, gets in Deep Sky Wonders. Frankly, in Scotty’s
time, much of which was before mega Dobs, uber eyepieces, and super filters, it
probably didn’t warrant much more.
The Cocoon is not easy. It did not respond to my OIII filter, and while a
Lumicon UHC filter improved it a little, it was still just barely visible as
an east-west elongated patch of nebulosity around a small group of stars. It
was best in the 35 Pan, being nearly invisible at higher power.
The sky stayed beautiful and blue Saturday... |
Walter Scott Houston was the dean of deep sky observers. No fooling and no
doubt about that, but he was a man of
his time, just as Admiral Smyth was a man of his. I say that because the
“controversy” Mr. Houston mentions concerning NGC 7000, the North America
Nebula, has the flavor of bygone days.
This controversy had to do with the visibility of NGC 7000, especially in smaller telescopes. Scotty rightly observes it can be
visible to the naked eye under good conditions, but he goes on to say it is invisible
in a 6-inch f/4 while easy in an 11-inch. That seems at odds with what most
observers experience today, that it is not hard from a dark site and is easiest
with small, fast scopes. Scotty, of course, was writing before nebula filters
became widely available and widely used—though he does mention an observation of the NAN with a UHC by Alister Ling. With an OIII, NGC 7000 and the whole
complex of nebulosity around it is a wonder in Miss Dorothy’s OIII
equipped 4-inch f/6.5 achromat.
Not that the NAN doesn't look good in a larger scope. It
dang sure did on this night. It was very bright in the 35 Panoptic with a Thousand
Oaks OIII. The Gulf Coast/Mexico/Florida region was, as usual, the most
prominent area, but the entire nebula and the Pelican (IC 5070) as well were
readily visible with a little scanning around. Several open clusters on the
eastern seaboard, NGCs 6996, 6997, and 6989 were obvious and attractive.
Deep Sky Wonders
gives considerable space to M31,
though much of it is devoted to questions about the galaxy’s visible extent,
its naked eye appearance, and its observational history rather than the
particulars of observing it. Scotty does get to that, however, noting in
particular the galaxy’s tiny, bright nucleus, which is one of my favorite features
and which many observers seem to miss.
I certainly didn’t miss much on Saturday night. I’ve had
better looks at M31 in the past, but maybe not much better. NGC 206, the huge star cloud in one of the galaxy’s
arms was obvious and appeared elongated and grainy, though not as good as it
was at the Chiefland Star Party in 2008. The
nucleus was, likewise, prominent, but didn’t appear as tiny and bright as it had
on that outstanding evening at the CAV. Otherwise,
two of M31’s dark lanes were visible with the 13mm Ethos, a sure sign you’ve hit
Andromeda on a pretty good night.
Barton Hall... |
In his earlier columns, Scotty was writing in an era when many
amateurs didn't observe even bright NGCs. That is particularly obvious
concerning NGC 6826, the Blinking
Planetary in Cygnus, a bread and butter object for novices these days. Mr.
Houston opines that the planetary is “not well known today.” And he doesn't even
mention the blinking effect—that the central star pops out when you use direct
vision and the disk is more pronounced with averted vision. That may be because
he observed the nebula with his 10-inch Newtonian; the blinking is more
obvious with smaller apertures.
It didn't blink at
all with old Betsy, with the slightly greenish disk being prominent with direct
vision. Despite the nebulosity, the central star was also readily visible. In the 8mm Ethos, there were hints of radial striations in the annulus. I tried the
TeleVue Big Barlow with the 8mm ocular in an attempt to get a better look at
these features, but no dice.
When he comes to the Saturn Nebula, NGC 7009, Scotty, in typical fashion asks rather than tells.
His question is, “What is the smallest telescope that will show the planetary’s
faint extensions?” These "extensions" on either side of the Saturn Nebula’s oval
disk, which made Lord Rosse think it resembled the planet Saturn in his proto-big-Dob,
are not easy. I’d answer “12-inch,” but the ring is often very difficult in a 12. That was not the case on this evening,
however.
NGC 7009 was good and high, and I was hoping to get a
glimpse of its ring, but I had my doubts. The feature has never been overly
clear in Betsy—not until this night, anyhow. The nebula was strongly blue, very
elongated, and when the seeing changed, the ring would swim into view. I could
see it at 187x, but had to take the power up to 374x to make it easy.
At that magnification, the ring still came and went, but when it was
visible, it was astoundingly visible.
Which brings to mind one of my maxims, “Amateur astronomers tend to use too
little magnification rather than too much.” If I hadn’t pumped up the power
here, I wouldn’t have gotten nearly as good a view.
M76, the Little
Dumbbell (planetary) Nebula in Perseus, was one of The Man’s fave objects, and
he often spread the word about it. Back in the hallowed day it was,
surprisingly, considered one of the more difficult Messiers. I’ve seen it
easily in a 60mm ETX refractor from a heavily light polluted suburban site, but fifty years ago a lot of us would read the oft-quoted
photographic magnitude for it, 12.2, and get scared off.
As Scotty says, on a good night with an 8-inch or larger
telescope this little thing is a showpiece. In Old Betsy with the 8mm
Ethos, the Dumbbell portion, the two lobes of nebulosity in contact, was
amazingly bright. Dark lanes criss-crossed the dumbbell, and arcs of nebulosity
were easy to see extending from each end of the object. There is little doubt the
LPR filters we take for granted help a lot with M76—it was much better with my
OIII than without.
M71 seems to be
another of Mr. Houston’s pet objects, since he devotes more space to Sagitta’s
globular cluster than most deep sky raconteurs do. That space is well deserved
in my opinion. One thing is sure, on my
DSRSG Saturday night the glob was bold and bright and resolved, visible as a
triangular shape—or, as Scotty calls it, an “arrowhead.” It is very loose and
in an incredibly rich star field.
In the past, there's been a question about the object’s
classification—is it a globular cluster or is it an open cluster?—and Scotty
makes note of that without coming down on either side. I’d say one look at the
cluster’s color-magnitude diagram makes its status as a glob clear.
Then it was time to ring down the curtain for the night with a
special object, the Phantom Galaxy, M74,
which, as I said last time, put on a surprisingly good show—for a dim
face-on Sc galaxy—at the 1994 Deep South. Scotty mentions the galaxy’s frustrating
and difficult nature, and I agree with him on that. It is frustrating and difficult—if you want to see the spiral arms.
It’s visible almost anytime as a smudge in an 8-inch scope under a dark
sky.
Actually, M74’s spiral is only difficult sometimes. Or maybe most of the time. When the sky is just right, with the “just right”
usually being a combination of steady seeing, low humidity, and dark skies, the Phantom offers
up a heaping helping of spiral structure despite the fact that Scotty seems to believe seeing the spiral arms is impossible even with a 20-inch scope. In Betsy, the arms weren't
as easy as they were in 1994 or on the above-mentioned night at the 2008
Chiefland Star Party, but they were obvious and beautiful.
My victory over M74 complete, I took a break, moseyed around
the field to see what my pals were up to, and visited Barton Hall's Little
Astronomers’ Room. Back at the EZ-Up, I started to grab a Monster Energy
Drink outa the ice chest. And stopped myself. It was almost midnight. and there
would be packing and the drive home on the morrow. Yes, not having to mess with
the tailgating canopy would help, but there would still be plenty of work to
do.

Gazing across the field, it looked like many of my fellow star partiers had had the same thought. The field was emptying out. Not having the EZ Up to protect the gear from dew meant much of my stuff was soaked and needed to be gathered up and stowed in the truck. It was time I pulled that accursed Big
Switch.
On the way back to the Lodge, I reflected on this year’s DSRSG.
It had been a very good one. I must admit that when I am not imaging, I always
feel a mite let down that I don’t have any “souvenirs” to take home at the end of
the event, but it wasn’t just any old visual observing I did this time. I felt
like a long overdue task was completed; a bow had finally been tied on the
DSRSG ’94 package with the completion of my old observing list. The icing on
the cake, if I can mix a few metaphors, was that I also advanced Project Scotty
at least a little.
After a restful night, it was time to say goodbye to the old
FRC for another six months (I sure hope to be back in April for the Spring Scrimmage edition of our star party).
Dorothy and I agreed we’d had a great time in 2014. Maybe not as great as in
1994— likely no star party will ever equal that one for us—but a great time
nevertheless.
Just after dawn, I was out to the chilly field to pack our
remaining gear in the truck and, after retrieving D. and our suitcases and
other room items from the Lodge, Unk pointed the truck east for the New Manse well
before breakfast. Unlike a few times over the years, I was sad to be
leaving and didn’t want to stretch it out with long goodbyes. 2014 was one for the books, muchachos.
2020 Update
There's not too much to say about DSRSG 2014 from the perspective of six years later. It was a great one. Probably one of the best all-visual DSRSGs I ever had, if not the best. Almost everything came together for a series of wonderful nights. I do have a few words, however...
The Feliciana Retreat Center
The FRC was an incredibly good site for the star party for years. Your old Uncle, who hates change, just naturally expected that to continue forever. Alas, in 2014 the handwriting was already on the wall. The poor food that year (which was destined to get even worse) was a taste of things to come, the beginning of the decline of the FRC thanks to economic woes, that impelled the star party to move to a new location in 2018.
Old Betsy

Project Scotty
In the wake of the Herschel Project's completion, I tried to get numerous observing projects off the ground, but none really took with me. I finally had to admit that various factors meant I just wasn't interested in taking on a big observing project again. Will that change? It could. I am planning essay the Herschel 400 from my backyard, something I am calling "The New Herschel Project."
The 2015 Spring Scrimmage
Following my success at the 2013 Spring Scrimmage, and the even greater time I had at the 2014 DSRSG, I was pumped and could hardly wait for the spring 2015 Deep South. I was retired and fancy free and ready for more star partying! Alas, weather killed it. But that's just the way it goes down here on the borders of the Great Possum Swamp, muchachos.
