Issue 616: Return of the Losmandy Redux-Redux
What’s been going on here at good old Chaos Manor South out on the borders of the Great Possum Swamp? Well, muchachos, it’s been wet. I mean thunderstorm after thunderstorm. Sure did put a damper on my latest (ham radio) contest, the CQ WPX CW. The antennas spent more time disconnected than connected. As for any astronomical endeavors? Hell, there was no chance of observing anything but clouds…and the month began to run out…
Specifically, I didn’t get to do something I’d really been
looking forward to, getting my Losmandy GM811G and my six inch
refractor, Big Ethel out into the backyard for a
tour of spring deep sky wonders, which will soon be on the wane. Well, if I
can’t use the GM811, at least I can talk about it. For such a nice and
capable GEM, I don’t hear much discussion of it, and maybe I can help rectify
that. If nothing else, this one fulfills my vow of not missing a month posting
a new article to the AstroBlog, even if said article is a short one.
“But wut in
pea-turkey is a GM-811, Unk? Wut is one, huh?” That’s easy enough. I think
most working amateur astronomers know about the Losmandy (Hollywood General
Machining) G-11. It’s a medium GEM that has been around for decades,
including being sold with a Celestron nametag on it once in a while. It’s a
reliable general-use mount that is a known quantity.
The G11 is a well-respected and reasonably priced mount, but some,
like your decrepit, old Uncle would have trouble handling the hefty G11, not to
mention big sister, the Losmandy Titan. There’s the smaller GM-8, but that doesn’t help those of us who need
more payload capacity than is offered by the littlest Losmandy. Scott
Losmandy and his colleagues had an idea… What if their mounts could be mixed
and matched? As in, produce a mount that uses the RA assembly of the
G11, but the declination assembly of the GM-8. And one with the RA of a Titan
and the dec of a G11. The mix and match mounts provide extra payload thanks to
the bigger RA assemblies, but keep the weight down.
So how did Unk wind up with one? Round about a dozen
years back, he was tooling along happily with his Atlas EQ-6 and Celestron Advanced VX GEMs, and
his beloved fork mount NexStar 11 GPS, Big Bertha. Getting a little older
was what happened, mostly. I suddenly found I could no longer safely lift the NexStar
11 onto her tripod. Oh, I still did it, but I felt nervous about it. At that time,
I really wanted to continue using a C11—or thought I did—and it ‘peared to me
the way out was to defork the OTA and put it on a GEM.
Unk being Unk, he didn’t want to spend much/any money on a
new mount and wondered if the Orion Atlas would suffice. After a few weeks of thinking, asking, and
reading, I reluctantly ruled that a “no.” The small counterweight bar and Vixen
saddle argued against it. A 9.25 is really the upper limit for an EQ-6, though
some have exceeded that. Also, I never got friendly with the SynScan HC. It
just never seemed as accurate goto-wise as my Celestron NexStar hand paddles.
Sure, the use of the EQMOD software corrected
the SynScan faux pas, but I was never real comfortable with that, either. What I
wanted, I decided, was a GEM mount that would handle a C11, one equipped with
the familiar and accurate NexStar HC.
There was no mystery as to which mount that should be. It
had been obvious for a long while that I should not have bought the EQ-6. What I shoulda done was wait a few months for the Celestron NexStar CGEM, which I knew would soon be released. But I got new GEM fever and bought the Atlas. I regretted that
decision for years. So, I sold the Atlas—which was a good mount, really, just not the mount for me—and
bought, yep, a CGEM, which to avoid offending my penny-pinching personality, I
financed in part by the sale of the Atlas and the NexStar 11 GPS fork mount and
case.

CGEM and C11: That's a lot of telescope, paw-paw. |
The problem? Damned, old Father Time (and a spate of
rather serious back problems). That rascal had made the CGEM and the C11 both
heavier and heavier. Honestly, I was back to where I had been with Bertha on
her fork mount. To be honest, I knew the 11 and CGEM were too much from the day
the big Celestron mount came to Chaos Manor South.
I practiced the art of denial for a couple of years before giving-in to the
obvious. Both mount and scope were way too much for me, the situation would not
improve, and both had to go.
So, I made a hard choice: To sell the C11, which was the SCT
I had honestly loved more than any other I’ve used over the last half century.
Luckily, I was able to send her to a good home where I knew she’d be very well
taken care of and used. Likewise, the CGEM went to a new owner. The good part
was I really hadn’t had enough time with the mount to get attached to it. I’d
think about setting it up, even with a C8 instead of a C11, and usually find
reasons I just had to use the Celestron Advanced VX mount instead. So, there I
was. C11-less, with my workhorse mount being the AVX.
So, what would I do? What would I do? Or…why do
anything? I had a nice Edge C8 and a nice AVX. Both worked fine. But the
lack of a larger mount began to eat away at me. While this was toward the end
of my time as a semi-serious astrophotographer, I didn’t realize that at the time.
I wanted more payload and better guiding for the very manageable 5-inch APO
Veronica Lodge, who’d replaced the C11. Mostly, though, I think I just
wanted to have one really nice mount. Something nicer than the Chinese GEMs
that had been my bread and butter for years.
But what? I
immediately ruled out Astro-Physics or an exotic European mount. I was never an
“8 hours of exposure” kinda guy, and it was clear even my relaxed take on
imaging with a DSLR was slowing down. So, if I wasn’t going for the high-priced
spread, and I was done with the Chinese mounts, then what? Actually, I did
consider an iOptron CEM60, but for various reasons, not just that it was of
Chinese manufacture, I decided against it. That left Losmandy, and their new
mount that had caught my eye, the GM811G.
Next up? Unk did some digging. What I found out about
the 811 was encouraging. As above, it consisted of the big G11 RA axis, and the
GM-8 declination assembly. All metal construction. Mucho stainless steel. Worm
gears on both axes, not just on the RA axis as I’d been accustomed to with my
Chinese mounts. Annnd…most of all, maybe, a payload for imaging of 50 pounds despite the GEM head only weighing 27 pounds.
Would I ever again put anything approaching a load like that on a mount either
for imaging or visual? Unlikely, but overkill is good.
As for the system itself? It’s not too much different from
those we’ve been accustomed to. There’s a hand control, which is connected to a
computer that bolts onto the tripod. Different alignment options are available,
including the ability to build models with multiple stars on both sides of the
Meridian, something my beloved NexStar systems lacked.
The Gemini HC is quite something. On one side of the hand
control are normal tactile pushbuttons for slewing the mount, the other side is,
yeah, quite something. It’s a full color touchscreen. Objects? Gemini falls
behind Celestron and Meade with 40,000, and that gave me pause. However,
realistically, how many more would I really need? You can enter RA and dec
values and go anywhere you want. Or send the mount to any object in the sky
with a PC.
And how about a PC? The Gemini computer is incredibly
flexible if you want to use a laptop in the field with the mount. You can
connect via good, old serial, something I’d really gotten tired of on the
Celestron mounts. Or you can use a USB cable. Or—get this—you can control the
mount over Ethernet. That would turn out to be my usual choice. No fooling with
com ports, no worrying about a too-long USB cable.
So… I decided I was gonna do it, buy me a Losmandy. I
wondered, however, whether I should order directly from the company or use a
dealer. I decided to call Losmandy and find out. I spoke to the famous Miss
Tanya and asked if I ordered direct, how long the wait would be (I’d gathered from dealer websites that it
could be weeks). She told me to hang on and she’d ask
Scott. She was back on in a minute, “Scott says if you order now, it will
ship this afternoon.” You can bet I whipped out my credit card. In addition
to the GM811G Gemini, I ordered an AC power supply and the lightweight field
tripod (no way I wanted to carry around the big G11 tripod). I did not
order the polar alignment scope. I’ve always hated those things and by this
time had progressed to using Sharpcap for polar alignment.
I was in an agony of anticipation, natch, but in just a few
days some big boxes labeled “Hollywood General Machining” were on the Chaos
Manor doorstep. You can read all the unboxin’ stuff here
(and even watch a little video), but it went very smoothly indeed. Then I
encountered a problem. The mount tended to experience “motor stalls” when
slewing in dec to a position near the horizon. A quick call to Tanya told me
what to do: Many mounts need an initial
gear adjustment depending on the nature of your payload—like my 6-inch refractor.
The procedure has a webpage at the Losmandy site, took only a few minutes, and
I never got a stall again with any telescope I’ve used on the 811.
From the evening of the day the Losmandy arrived, it’s
performed splendidly in the field—I looked on the fact the sky didn’t cloud-over
the minute I received the new GEM as a good omen. As long as I didn’t try to carry
the mount head with its BIG counterweight bar in place, setting the Losmandy up
was no problem for my poor back. The lightweight field tripod? It was very
steady even with my 6-inch refractor onboard, and I sure was glad I’d eschewed that
G11 tripod.
Gemini 2 touchscreen HC. |
It's been a long time, yeah, since I imaged with the
mount. In fact, I haven’t even used it for visual in a while, about five
years as a matter of fact (ulp). But why? The near-fatal accident I suffered in
early 2019 put an end to my observing for almost a year. When I was (more or
less) back setting up scopes in the backyard? The aftereffects, particularly
with my right arm, which still doesn’t have much strength, discouraged me from
using any but the smallest and lightest instruments. Five years ago, just to
say I could, I got the mount assembled but almost dropped the 6-inch refractor in the process of getting it into the mount’s saddle, which further discouraged me.
Now? Well, campers, I’m five years older, but I feel good.
I have a better idea now of what I can lift safely and how to lift it. I have
every intention of cruising the deep sky with Big Ethel and the Losmandy. As
soon as the sky clears. Whenever that is…

Issue #615: Goodnight Meade, Goodnight Orion…
Near-about a year down the line, this is something I haven’t had much to say about, muchachos. Quite a few of y’all have asked my opinion on it, though. Why haven’t I dished on this earth-shattering (in a small amateur astronomy sort of way) subject? It just didn’t seem possible, I reckon, not till I did some ruminatin’ on it, anyhow. “Unk, what in the hail are you goin’ on about now?”
I’d be amazed if you haven’t heard, but to recap, last July,
July of 2024, that is, a rather disturbing rumor began circulating in the small
world of online amateur astronomy: Meade
Instruments, once the largest telescope maker in the world, had ceased
operations at its California offices and its Mexican factory. The workers had been sent home, and Big Blue was dead in the water. At
first that sounded plumb impossible. Not Meade! How could such a
giant—well, formerly, anyway—fail? Many were in denial. The Cloudy Nights BBS soon locked the thread on the subject.
Unk? I got word from my editor at S&T, Sean, that pretty
much confirmed Meade was closed. Then the other
rumor bubbled up, that not only had Meade closed its Watsonville, CA office,
but that its parent company, Optronics Technology, the owner of Orion
Telescope and Binocular Center, had shuttered
its Orion brick and mortar stores. I
wasn’t too surprised about Meade, but at first I was really gob-smacked about
Orion, who, like Meade, had been a fixture in astronomy since the 1970s.
How could both Meade and Orion suddenly be kaput? Some in our community simply refused to believe it. After all, their websites were still up, and
they seemed to be taking orders. But then, as the days and weeks passed,
the Orion website dropped off the air, followed, finally, by Meade. The threads
on the subject at Cloudy Nights had been unlocked well before that, and few
doubted any longer that both were gone (and also Coronado solar scopes, which Meade had purchased years before) and gone for good.
How? A little cogitating about both companies answered that question…
Meade was lucky
to still be around in 2024 in any form if’n you ask me. They’d been through at
least four different owners and had been making most of their amateur telescopes
in Mexico since 2009. The enormous and iconic Meade plant/offices in Irvine,
California full of giant SCTs and serious, white-coated workers (according to the
pictures in their catalogs, at least) was long gone.
The Meade of 2009 claimed that move was intended to expand
production. Few believed that. Most of us suspected Meade was going maquiladora (and buying a lot more from
China than they had been) to save money and remain competitive. After all,
their number one rival, Celestron, was now owned by Chinese optical giant Synta and didn’t have to pay California
wages. Whatever the reason, it didn’t seem to help much, and a mainland Chinese
firm, “Ningbo-Sunny,” picked up the obviously ailing Meade Instruments in 2013. Some
hoped for the best. Unk wasn’t so sure…
Meade soldiered on under Ningbo, but took a one-two punch in
the gut with the disastrous introductions of the LX-80 alt-AZ/EQ goto mount and the LX-800 GEM. Neither mount worked well, or
sometimes at all. Now, it’s true that both had been developed pre-Ningbo, but
the fact that post-Ningbo whoever was calling the shots decided to go ahead
with two Nowheresville products showed the company’s basic problems hadn’t gone
away. Despite that, for a few years their bread and butter (amateur astronomy) products
like the LX200 seemed OK. But then, around 2016, your old Uncle began to hear
about QA issues with just about anything with a Meade sticker on it.
My opinion was “rut-roh.” Given what I knew, I didn’t
believe there was anybody at Orion/Optronics capable of running Meade. I also
didn’t believe anybody left over from the Ningbo years had much of a clue,
either. The result? Orion was able to
continue Meade for three years but at a reduced level of activity.
“Orion Meade” offered at least one newer product, an update
of the LXD-75 GEM (a competitor for Celestron’s VX mounts), the Chinese-made LX85, which
debuted toward the very end of the Ningbo period. I wrote the Sky &
Telescope Test Report and was able to use the LX85 extensively. I was
frankly impressed. It seemed like a lot of mount for a little money. But then, a
year or two after the Orion buyout, I began to hear not everybody who used one was
quite as sanguine about the LX85 as Unk.
It was apparent the QA problems had not gone away with the
coming of Orion. Worse, the difficulties didn’t seem to just be the usual Meade
Achilles heel, electronics, but variations in mechanical quality involving the
gear system. I wondered whether the mount I used would have continued to be a
good performer if I’d been able to use it longer. I suspected the answer was
“nope.” A really bad sign? Few
people I talked to, few amateur astronomers, were excited about Meade
products anymore.
The end? Which straw, exactly, broke the Meade camel’s
back? There’s been a little that’s leaked, indicating disarray at Meade in
the months before the end, but who knows? Maybe somebody will write a book. I
don’t think you need a book, though. I suspect the culprit was just the accelerating
decline that began after John Diebel, who started Meade on his kitchen
table in 1972, retired for the second time in 2003. Nothing seemed quite right
after that, and I don’t know of anybody who thinks Mexico-made Meade SCTs were
as good as those produced in Irvine, California. Above all, their fate was
linked to that of their final owner, and Orion
hadn’t been doing well for a while, either…
The business model? Orion products were always a little more
expensive than the same or similar things elsewhere, but they made up for that
with customer service that was top-notch. They were especially known for
helping beginners get their start in amateur astronomy. Oh, and their wonderful old catalogs—which
customers got in the mail at least once a month. In those days, in addition to
Orion-branded equipment, they sold products from various sources including
Vixen and Celestron.
So, what happened? Same-old, same-old as Meade.
Orion’s founder sold out and retired and the company went through a couple of new
owners, neither of which had Gieseler’s vision. Orion diminished with every ownership
change. The business model also changed. The second and third owners, Imaginova
(Lou Dobbs’ space.com company), and the “new” (employee-owned) Optronics
Technologies went almost exclusively to Chinese imports.
Imported products were certainly nothing new for Orion. Gieseler noticed this little Chinese telescope (from Synta), an 80mm f/5 refractor, and thought his customers would like it. Man, did they ever! Even after the coming of the Short Tube 80, though, Gieseler didn’t go Synta 24/7. But, to keep up with the competition, I reckon, there were ever more "Orion" Synta scopes, mounts, and accessories.
At first, the shift in focus to Chinese products was a
winner for them. Orion had a pretty good lock on Synta’s SkyWatcher gear for
quite some time. But that changed. Suddenly there was SkyWatcher USA, and folks
noticed you could get an EQ-6 mount branded “SkyWatcher” or an 80mm f/5 refractor branded “Celestron” for less than an
Orion Atlas EQ-6 or a Short Tube 80 cost. Synta was not at all shy about
selling to Celestron. Toward the end, Orion did go back to selling products
from a wider array of makers, but I'm not sure that helped in any way.
The almost exclusive emphasis on imported stuff wasn’t the only thing that changed, though. Soon
enough, those good, old catalogs became less frequent and then disappeared. You
might say there’s no need for print catalogs today, but lots of folks still liked
them, and they set Orion apart. Then,
their customer service began to circle the drain.
One thing that POed a lot of people (“put out,” this is a
family-friendly blog) was an ongoing policy of not providing service or parts
unless you were the original purchaser of the product. That made sense for Orion,
perhaps, but drove a lot of potential customers away. By the end, their
customer service wasn’t A level anymore. To hear some tell it, it wasn’t
even F level.
As for what exactly
brought Orion down and Meade with it? Supposedly, it was supply chain issues that began during the pandemic. We do have some numbers, though, and from what I’ve seen,
the amount of stuff they shipped had been on the decline for years before the pandemic. Ironically, covid
was a boon for some astro-merchants (including Meade), what with people
wanting something to do safely at home. Likely, it was just that Orion didn’t
have anybody in charge who knew the astronomy business, even if they were
equipped with a nice MBA. Taking on a Meade that was already, like them, in
poor economic health, probably hurt more than it helped.
Yep, same story for both. Two legendary (in a small amateur
astronomy way) companies change hands and lose more and more of what made them stand
out with each change. So, goodnight, Meade, goodnight, Orion. I still
have fond memories of you both, and I reckon we will just leave it at that.
Might somebody buy the rights to either name and crank either up again? Why
bother? As both wound down, those names acquired plenty of baggage. It would
probably be best just to start afresh.
What happened to all those
Meade telescopes, you ask? Apparently, there was a pretty good amount of
gear left over, and dealer High Point
Scientific bought all those pallets of scopes and accessories at the
auction of Meade’s remains and is selling them at a discount. I believe they also acquired whatever
inventory Orion had on hand. I see the various domain names are also up for
sale, and wouldn’t be surprised to see telescope.com and telescopes.com, at
least, come back to life.
Despite it all… Meade gone? Orion gone? I still
have a hard time wrapping my head around that one. But that’s just the way she
goes, I guess. It has always happened. Giants in the business—Unitron,
Criterion, Cave, Edmund, Jaegers—are gone and leave not a rack behind. Hell,
even Questar appears to have fallen on hard times. Nobody is immune to that
old devil CHANGE.
Next time? A happier subject for sure: The Return of
Unk’s Losmandy.

Issue #614: Uncle Rod, Armchair Astronomer?!
I know, Muchachos, I know, thisun was ostensibly going to be about me getting my 6-inch refractor, Big Ethel, and my Losmandy GEM into the backyard. My intentions were good, but between stormy late-winter weather and your dilapidated old Uncle being under the weather for a while, that didn’t happen. I still intend to get Ethel and the mount back up and running, and I definitely want to try the SeeStar smartscopes’ new equatorial mode, but that will wait for clear skies—whenever we get those. I am feeling much better this week, though, so that is something, I reckon.
Anyhow, what’s that title about, you ask? “Armchair
astronomer”?! Ol’ Unk’ was once purty hardcore observing-wise. His
observing runs, particularly during the vaunted Herschel Project,
routinely went on till three or four in the a.m. or not infrequently till dawn
itself. He was often known to snicker, “Astro-wimps!” at the sight of observers leaving
the field at midnight or one. Has that changed?
You betcha. I won’t bother you with my litany of
aches and pains, nor more complaining about growing older, nor (again) recounting
the close-to-fatal accident I had in ’19. I’ll just say, I’m in my 70s now,
and have had to slow down in a lot of areas not just to include astronomy.
Why? Well, I have a more difficult—much more difficult—time hauling gear
around, even into the backyard. I have a lingering (and mostly irrational) fear
of falling in the dark. And a late night for me is now ten or eleven.
That don’t mean I don’t get out with telescopes, though.
The coming of the smartscope is, as you know if you’re a regular reader, been a
boon for your aged hillbilly of a correspondent. I still do visual observing, too, usually
with modest telescopes like Miss Tanya or one of
my smaller refractors. I did get the 10-inch, Zelda, out over the summer,
however, and, as above, I’ll have the 6-inch refractor up and running again soon
(I hope).
Almost all my observing is from the backyard now, yes,
though I did get to the Deep South Star Gaze autumn before last and
would like to go back again. I still teach astronomy, and helping my students do their
outdoor labs with telescopes ensures I’m under the evening sky once in a while. I
continue to write for Sky & Telescope, mostly Test Reports,
which also requires my little self to be under a starry sky.
Night by night and day by day, though? I won’t lie to
y’all. I am purty much that astronomer we Active Amateurs laughed about
through our 30s and 40 and 50s and even into our 60s: THE ARMCHAIR
ASTRONOMER. That is, much of my contact with the Great Out There day by day and even night by night is now in
the form of books. I snuggle down on the couch, open a tome about my
astronomical obsession and let my mind wander the Universe. What are the ones I
most often turn to when I go voyaging?
Galaxies, Timothy Ferris (1982)
This large-format coffee table book from 1982 has been very
important to me. What is it? Oh, there’s some text on the subject of galaxies, natch,
but mostly it’s just big—BIG—13” x 14” color photos of island universes. I still
like to look at it, but in the early 90s, it was a lifeline. I was in
the midst of the dissolution of a truly misbegotten marriage, and Galaxies
allowed me to fly free for a while.
How does it stand up today? It holds up well. Sure, the images from top ground-based observatories of the day began to look a little second-class with the coming of the HST, and amateur imagers have now exceeded some of what’s in the book. However, many of the astrophotos here are still amazing, and the large format makes the best breathtaking. I don’t think Galaxies is still in print, but it is readily available from Amazon.
Burnham’s Celestial Handbook: Robert Burnham Jr.
(1978)
Everybody who’s even begun to earn their stripes as a
deep sky observer knows about this one. There are “better” field guides to the
universe beyond the solar system today, like Night Sky Observer’s Guide.
But none are written in the thoughtful, poetic style of Bob Burnham. When
talking about a constellation—the book is arranged by constellations—we may, for
example, take a side-trip with Bob and
talk about ancient coins for a while. It worked all those decades ago when the book was
initially released in looseleaf installments, and it works today.
I don’t go to Burnham’s for eye candy. There is none in its
pulp pages. When I snuggle down in that armchair and read this now, it’s for
Bob’s writing. And for the nostalgia. All those long-ago days when I sat with
these three volumes and a steno pad and made lists of “need-to-sees” for the
coming of night.
Skywatching: David Levy (1994)
You’d a-thought that by the time we got to the freaking
1990s, your old Uncle Rod would have been way past a beginner’s book on astronomy/amateur
astronomy like Skywatching. Nope. Mainly because this one, published by
The Nature Company (who’ve been gone for nearly three decades now), is
profusely illustrated as were most of their books. It’s just fun to look at
those pictures of everything from telescopes to deep sky objects. That’s not
the only reason, though. The authoritative text by David is to be relied upon.
When my increasingly forgetful self can’t remember some astronomy something, I
can turn to Sky Watching.
What really draws me back to this one on evenings when it’s
cold or cloudy or I just don’t feel like even dragging a small telescope into
the yard, though? Dorothy and I received this as a wedding gift upon our
marriage in 1994. Looking through it takes me back to the wonderful times when
the amazing Miss D. and I were newlyweds.
All about Telescopes/How to Use Your Telescope: Sam
Brown (1967)
Yeah, I probably know a fair amount about telescopes this
far down the line, but I still like to browse Sam Brown’s magnum opus published
by the old Edmund Scientific Company (still around, but nothing like
they were in the glory years). Why? While Sam knows his stuff, it’s those
wonderful old 60s-style illustrations. They are nostalgia itself.
Yes, All About Telescopes is now available as a free
pdf download from archive.org thanks to the people who now own Edmund. But you
can still get a print version, and that is just what you should do. As for me?
The thunder is booming; think I’ll take a stroll through this wonderful book—or
maybe just the excerpt How to Use Your Telescope that was included with
my Palomar Junior.
Norton’s Star Atlas: Arthur P. Norton (15th
Edition, 1964)
While wonderful for cloudy night browsing, you probably
wouldn’t want to use this as an accompaniment to even binocular observing. It’s
just not deep enough. It has stars down to magnitude 6, the Messiers, and a
selection of deep sky objects from the NGC (but with Herschel numbers!), 500 deep sky objects in all. Course, when I was a little nipper with a little telescope this took me—I
thought—way deep into the Universe. The nostalgia factor? I still cringe at how
many lawns I had to mow to pay for this one in 1966. Yeah, I cringe, but it’s a good
cringe.
Norton’s was updated some years ago for the current epoch, the charts redrawn, and the text rewritten. Not surprisingly, it’s just not the same and I ain’t interested in it.
Stars: Herbert Zim (1965)
You can read all about this here,
so suffice to say this book by Herbert Zim, a “Little Golden Guide,” is what
made me an amateur astronomer, game over, end of story, zip up your fly. What
draws me back is the nostalgia brought on most of all by Jame’s Gordon’s
wonderful little illustrations (up above).
And that’s kinda it for a rainy Monday when I have to make my way to the university to teach astronomy to the next generation. I hope the storms rolling over us aren’t a foretaste of what April is to be in Possum Swamp. I really do want to get that big glass into the night, and I am a-gonna do that—scout’s honor!
Below you'll find a link to one of the little companies serving the astronomy community. One that deserves your support. I go a long ways back with Daryl and his Shoestring Astronomy store. How far back? To when I needed to do ST-4 guiding through my first laptop's parallel port!
That doesn't mean Shoestring Astronomy is a thing of the past—not hardly if you use a SkyWatcher mount. Daryl sells a top-quality EQDIR cable that allows you to run your mount with the excellent (and free) EQMOD software rather than the somewhat clunky SynScan hand control. I had to sell my Atlas EQ-6 some years ago because it had become too much for me physically as a portable (!) mount. But almost every time I used it for anything but quick looks, the Shoestring EQDIR cable was there.
Not that I've stopped using Shoestring products. Y'all know I ain't the world's most up-to-date and advanced astrophotographer, that I still like using my (very) old Canon Rebel DSLR. We are growing old together and still having fun. But to enable long exposures, a shutter control cable connected to the PC is required. That's Shoestring's DSUSB.
Those are just a few of the useful but hard (or impossible) to find products Daryl makes and makes well. There's plenty of other useful stuff on offer, and he has some interesting new products coming. Support him, we need Shoestring to stay around for a long time to come!

Issue 613: How about a Challenge?
Project Burnham, wherein I plan to visit all the deep sky objects highlighted by Robert Burnham in his famous handbook, will continue, muchachos. But I thought you might like something new; that you might like to hear about a fun challenge NASA is running this year, “Hubble’s Night Sky Challenge.” Wut’s they-at? NASA says:
Do you have a telescope? Would you like to see some of
the same night sky objects from the ground that Hubble has from space? We
invite you to commemorate Hubble’s 35th anniversary by accepting our year-long
stargazing challenge. On a clear night, find a safe location with a dark sky
away from bright lights, point your telescope skyward, and with the help of
star and finder charts, gaze upon some of the same iconic nebulae and galaxies
Hubble has observed. How many of them can you find?
They go on to explain NASA is working with the Astronomical
League (yes, it’s still around, apparently) who will handle issuing certificates of achievement for those who successfully sketch or
photograph the objects.
I’m not very interested in certificates these days (though I
admit I did my happy dance when I realized I finally had enough countries to
qualify for the ARRL’s DXCC CW). Certificates or no, it looked to me
like it would be mucho fun to get out and observe/image as many of these
nice DSOs as possible. If you are interested in certificates, you can
read all about ‘em on the Hubble’s Night Sky Challenge page.
There’ll be a list of deep sky targets for each month of
2025 with the selected objects, naturally, being those Hubble has imaged over its
long career. The targets thus far have been a nice mix of five or six objects
ranging from the easy to the slightly more difficult. For example, January’s challenge
included M42 on the easy end and NGC 2261, Hubble’s Variable Nebula, on the
more difficult.
My only complaint? Other than the Messiers, the
objects are identified with their “Caldwell” numbers. If you’ve forgotten about
the Caldwell, it was the “best of the NGC” list composed by the late Sir Patrick Moore
and widely published way back in the 1990s. Hey, I’m as big a Moore fan as
anybody—I likely wouldn’t have taken up amateur astronomy without his wonderful
books—but his Caldwell list never caught on with me or most other deep sky
observers. Not that it was bad…it was quite good, but had been done as well
or better before. NGC 2419
Few of us know the C numbers. I don’t recall ever
hearing anybody talking about getting out in the back forty and observing “C7,”
for example. So, when perusing the Hubble’s Challenge lists, you'll have refer to
a cross reference to the Caldwells’ NGC numbers, which is slightly annoying. Also,
I recall some of our colleagues were slightly annoyed with the list itself,
which they thought was overreach and self-promotion on the part of Patrick
(though he didn’t call it the “Moore List;” Caldwell was his mum’s maiden
name). I didn’t care about that. Patrick Moore was an icon, and if he’d
called it the “Moore List,” I’d have been fine and dandy with that. In
terms of Hubble’s Challenge, it is not a huge deal, since each month’s list
only includes a handful of C objects.
So…anyhow…I don’t know if I’ll bring Hubble’s Challenge
to you every month, but I will for sure bring some of them to you,
and I believe you’ll have as much fun with it as I have so far. This time of year, it’s nice to have a simple little
project to tone up the deep sky observing muscles many of us (including your cold-averse
old Uncle) allowed to atrophy this stormy winter.

M46 |
Hokay, let’s go… ‘Twas a pair of quite acceptable late
winter nights when I set up each smartscope in succession. It was damp, but not
unacceptably so; at the end of the evening Evie and Suzie had fine patinas of dew, just a hint of what we can expect when spring comes.
This was only my second night out with the Unistellar, and I
still felt like I was flying by the seat of my pants when it came to her iPhone
app. Luckily, I had a set of simplified (always a good thing for
your simple, old Uncle) instructions from my Smartscope mentor, Jack Estes.
Mostly it went smoothly, and I think Evie did a good job despite my fumbling.
When I first connected Evie to the phone, I was prompted to
do an update. I’m not quite sure what that accomplished, but it was my
impression the wi-fi connection was more robust. I had the phone in the Sunroom
and Evie out in the backyard, and, unlike first light night, didn’t have a
single disconnect. Main takeaways? I think I dialed in focus fairly well, but
believe I can do a little better. It also appears to me that some collimating may
be required. Verdict, though? No fuss, no muss, though not as much no fuss no
muss as Suzie.

NGC 2403 |
All pictures here are the simple .jpgs that came out
of the scopes with only the most minimal processing…
NGC 2419
Ah, yes, the famous Intergalactic Tramp in Lynx. Or
famous when your Uncle was a young man, anyhow. This 9th magnitude,
4’36” diameter fuzzball discovered by Sir William Herschel is a distant globular
cluster now known to lie a staggering (for a glob) 275,000 light years
from our little rock. It has long been known to be a far-far-away cluster, and in
the 1920s legendary astronomer Harlow Shapley speculated it was not bound to
the Milky Way and sailing through the night on its own. Which led to the “Intergalactic
Tramp/Wanderer” appellation. In the 1990s, however, it was determined it does indeed orbit
the Milky way despite its distance. Which killed some, but not all, the romance
of this distant ball of suns.
What was it like for the smartscopes? Suze had no trouble
at all finding and centering the fuzzball, but, alas, given her wide-field
nature, was unable to resolve more than a few of the cluster’s halo stars. Would
it have been different from a dark site? Maybe, but a dark site isn’t often
on your old uncle’s agenda in these latter days. Evie? She made this
globular look like a globular, her image showing off plenty of resolution.
Messier 46
Puppis’ bright, magnitude 6.0, 20'00" across cluster
is known and loved by even novice observers. It’s not so much that it’s an
outstanding open cluster in a telescope…it’s kind of large, is set in a rich
field, and doesn’t pop out from the background as much as the best-of-the-best open clusters do. Its
popularity with observers is because it holds a hidden gem, a small planetary nebula, the tiny ring of
magnitude 10.8, 1’10” diameter NGC 2438. Even small scopes will show this
ghostly little thing, which, incidentally, is thought to be a foreground object
not associated with the star cluster.
Caroline's Cluster |
NGC 2403
There is no doubt this big (21’00”) bright (magnitude
8.9) spiral galaxy in Camelopardalis is one of the wonders of the northern sky.
The true wonder of the thing, though? How Charles Messier missed putting this
one on his list. Be that as it may, it was finally observed and cataloged by William
and Caroline Herschel in the 18th Century. Yes, it lies in a subdued
and often bypassed constellation, the camel-leopard, but you owe it to yourself
to give it a visit.
How did the girls do on this one? It was pretty much
a tossup. Suzie’s image is maybe a little smoother…but I prefer the color in
Evie’s portrait of the galaxy. Also, it was verging on the hazy on Suzie’s
night, giving Evie further advantage.
NGC 2360
William Herschel’s sister and fellow observer, Caroline,
doesn’t have many objects attributed to her alone, but there are a few,
including this outstanding open cluster. Lina found this one—maybe during one
of her comet “sweeps”—on the evening of February 26th 1783, and it
became the second object in her personal list. As y’all know, Unk goes ga-ga
over most anything having to do with Willie and Lina, but Caroline’s Cluster is
a purty outstanding galactic cluster (in Canis Major) on its own. This magnitude 6.2, 14’00”
across clump of stars is just about perfect for small-medium size scopes.
Well, finally…a win for Miss Suzie. While Caroline’s Cluster
isn’t too large, it’s set in the richness of the Milky Way, and the SeeStar S50’s
extra field made it just look better. But it was good in Evie as well,
no doubt about that.
NGC 2392
And, yet another Willie Herschel discovery, the famous
Eskimo or Clown Face magnitude 9.6 planetary nebula in Gemini. It is another
object well-known and beloved of deep sky observers old and new. Small scopes
show a greenish puffball with a brighter center/central star, while medium-large
instruments begin to unlock details, like the ruff of the Eskimo’s parka.
The Eskimo |
And that was that. Easy-peasy. Both smartscopes knocked
off every challenge object. In fact, they laughed at the idea these were
“challenges.” That said, I believe as I gain more experience with both
telescopes, I will improve on what they can deliver.
As for NASA’s Hubble’s Night Sky Challenge? I had fun. I was
afraid the rather well-known nature of the objects would make for a ho-hummer
of an experience…but no. In fact, I had a terrific time. So
terrific that maybe I’ll continue next month after all…

Issue 612: Where are the Smartscopes?
![]() |
M3 with Intelligent Denoise and cropping... |
Oh, before I forget—easy for me to do these days—happy
new year, y’all! I decided to forego the summing-up of last year I’ve been
accustomed to doing as a January AstroBlog entry these many years. Doesn’t seem
to be much point to it anymore. If you are curious as to
what your Old Uncle was up to in ’24 (for some unfathomable reason), just
cruise through 12 monthly installments. Easy enough to do. Ain’t like the
olden days when there was a new article here every fricking week.
Anyhoo, this will be a fairly short one…maybe…y’all
know how Unk do run on. Mainly because a lot went on at Chaos Manor South the
previous week. Beginning with Winter Storm Enzo, which brought
Possum Swamp more snow than we’ve seen since that hallowed, long-ago year of 1973.
Then there was (amateur radio) Winter Field Day, which I was determined
to participate in (and not from home) despite the cold. Finally, I had assignments
from two astronomy magazines to get out the door. Be that as it may
be… following the little old AstroBlog’s renaissance, I swore to get an article
up every month, so here one is…
Unk
![]() |
M33 stacked and processed manually. |
What else was notable about my time testing the S30? It
showed me this scope (and the S50) are capable of a bit more than I thought
they were. I am lazy these latter days, but I thought I should at least take a
shot at downloading the fits subframes from the telescope and stacking and
processing them manually with Siril (the free image stacking/processing
program). That process will be the subject of a future blog post but let me say
even for your bumbling old Uncle it wasn’t that difficult and hinted at
what the S50 and S30 are capable of in skilled hands.
What didn’t I have time to do? Between the need to
get those articles done, and the storm, I haven’t been able to get my
“new” Unistellar Equinox back under the stars. Believe you me, that is
Unk’s number one (astronomy) priority for the coming month.
ZWO
Is ZWO the king of smartscopes? Well, maybe in a way.
Their two units, the S50 and S30, are inexpensive and are in the hands
of a lot of amateur astronomers, old and new. Their app is also full featured
and capable. Frankly, the company had a leg up thanks to years of work on their
ASIAIR, which is a Wi-Fi-enabled widget that can turn your conventional
telescope and goto mount and camera into something like a smartscope.
Applying this technology to the SeeStars has made the little smartscopes nearly
impossible to beat for their prices and ensures they really punch above
their weight class. The company also continues to update their app/features
at a nearly dizzying rate.
So, what’s the latest with the ZWO? A lot of folks are
speculating about a “better” SeeStar. Maybe one with more aperture, say 80mm,
yeah, an S80. Bigger chip. Built-in wedge for equatorial mode. I
wouldn’t be too surprised to see some/all of that happen. But… Size doesn’t
scale linearly with aperture, alas, as somebody who’s only gone up a mere 2
inches of aperture from 10-inches to 12-inches sure can tell you. And
neither does price, my friends.
20mm more aperture makes the S50 considerably larger and
heavier than the S30. Goin’ another 30mm larger than the S50 will do the same—on
steroids. The result will be noticeably less portable and quite a bit more
expensive. I would be surprised if ZWO could bring in an 80mm f/5 for 1000 US$
and keep the quality comparable to the 30/50. Going to a good 80mm APO objective
will eat a lot of money all by its little self. Still, could happen. Probably
will. However, the S30 is still new, and I don’t think ZWO will want to
rain on its parade too soon.
What has the company done in addition to releasing Little Sister, the S30? Hoo-boy! They’ve added a feature to their app (same app works with both scopes) some thought was pie-in-the-sky: Mosaic (“Framing”) Mode. The SeeStars can now assemble multiple images into larger ones. The feature is easy to use; you just stretch and rotate the image “frame” in the star atlas.
And ZWO ain't done yet updating their app yet. Not hardly. Next up according to the company is Equatorial Mode, which will make it possible to tilt the scope over to polar align it. That done, pictures will not suffer from the problems of field rotation inherent in altazimuth scope mounts. Some users have already been able to use EQ mode by tilting the scope over to point at the Celestial Pole and “fooling” the app. An official equatorial mode will make workarounds unnecessary and will also add polar alignment tools. ZWO says this will be in the app’s next update.
Unistellar
![]() |
Equinox 2 |
The latest? The Equinox 2, which improves on the original
with a more advanced, higher resolution imaging chip and improved optics.
My take from what little I’ve been able to do with my Equinox 1 so far? They
are well-made telescopes, and it’s nice to have more aperture and focal length.
The app that controls them is fine. I do wish it featured a Station Mode ala’ ZWO
that would allow you to connect the Equinox to your network rather than to your
smart device directly. But all in all, works well. Stay tuned for more
on Unistellar when I gain more experience with this impressive instrument.
Dwarf Labs
All I know about the Dwarf II and III is what I’ve read
on the Internet and seen on YouTube. I’ve yet to get my paws on one of
these odd-looking little Smartscopes. That said, I haven’t been overly
impressed by what I’ve seen of the Dwarf II’s output. The Dwarf III? That may
be a different story. The new scope (Dwarf Labs is taking pre-orders now) appears
to produce impressive wide-field images with its 35mm f/4.2 optics. One big plus is it is EQ Mode ready
and includes polar alignment software in its app. The app seems a lot more like
ZWO’s take than Unistellar’s, containing a star atlas and other things
comparable to what ZWO offers.
Caveats? If you
can believe what you read on the Cloudy Nights BBS, Dwarf Labs has had
significant problems producing the Dwarf 3. Including QA problems. At
any rate, when I last checked, there’s a 4 – 5 month waiting list.
Vaonis
The latest from Vaonis, the Hestia, is an inexpensive ($300) smartscope. Or maybe it's not a smartscope or a telescope of any kind. It's a device that attaches to your smartphone and allows limited imaging of the sky. Maybe "advanced telephoto adapter that runs from an app on your phone" is a better description than "telescope." At this time, it is capable of producing decent solar and lunar images. It can image deep sky objects, too, but due to the Hestia's lack of tracking, they are mostly in the "I'm surprised you got anything at all" category. Vaonis says they intend to introduce a tracking mount for the widget in the future. We'll see.
Celestron
I’ve still haven't used heavy-hitter Celestron’s Origin
smartscope. Well, that ain’t quite right. I’ve used pieces and
parts. Celestron, you see, was able to put a smartscope together from
off-the-shelf/near off-the-shelf components. The mount is based on their time-tested
Evolution Wi-Fi enabled mount. The tube is a downsized model of the Rowe-Ackerman
astrograph— this model is 6-inches. The camera mounts to the scope via Celestron’s
good, old Faststar corrector mounting. The app is based on SkySafari—Celestron
has had a long working relationship with the SkySafari folks.
![]() |
Celestron's Origin. |
Might Celestron fix some or all of this? Maybe. I haven't heard new smartscope news from them lately. The possibilities are there, however. There’s no reason to think the mount couldn’t be used in equatorial mode with an updated app. The Faststar camera mounting means a more advanced camera could replace the current one or be offered as an option. And the price might be brought down some after Celestron (Synta) earns back development costs.
Me? I am impressed by the Origin’s images…but… Remember,
all I’ve seen is pictures of the scope. But… it looks to me as if
we are getting into the realm of too-big telescopes, telescopes I am too
lazy to use or literally unable to use anymore.
STOP THE PRESSES! The word on the street, the rumor, the scuttlebutt is the next release of the Origin app/firmware will provide support for equatorial mode and the StarSense autoguider.
On the Horizon at Chaos Manor South…
As above, my next goal astro-wise is to get friendly with
the Unistellar Evolution. When? When it ain’t so freaking cold. Oh, its
warmed up compared to our frigid conditions last week, but—wouldn’t you know
it?—the warming trend has brought clouds with it.

Issue 611: Yet Another Christmas Eve at Chaos Manor South
Last season's SeeStar shot... |
This little ritual of mine has been going on for almost as
long as I’ve been an amateur astronomer, getting started one Christmas in the 1960s when everything was on
the cusp of great change. As it always seems to be when you are young. I kept
it up over the years, but if not as an afterthought, not as something of great import
either. It seems to have reassumed some of its old significance in these latter
days, though. Maybe because I am old now, and the days when my friends, Jitter
and Wayne Lee, and I admired the Hunter with new eyes seem strangely close.
Not to sound overly melancholy or sumpin’; it’s been a bright and calm Christmas, mostly, for me and Miss Dorothy. And, not completely ho-hum, either. There was the slightly raucous W4IAX (Mobile Amateur Radio Club) Christmas Party at Heroes Sports Bar and Grill. Your ol’ Unk had “some” cold 807s and a couple of shots of the Cuervo Gold but nevertheless managed not to run amok or even make a scene!
Other than that, though, ain’t no denying it was a quiet Christmas. That’s just the way it’s been with the kids grown and far away as the years of this strange new century have rolled on. Those enormous, storied Christmases at yore at old Chaos Manor South in the Garden District are but shadows of the past. Which is fine, since your curmudgeonly Uncle now much prefers, “Quiet, no rows, no thank you; I believe I shall just stay home.”
Enough of that malarkey and down to brass tacks. The
scope I’d use if it cleared would be little Tanya,
the rescue scope. Oh, my old Palomar Junior sits next to Tanya in my radio
shack/workshop here, The Batcave, and that telescope would be nostalgia itself.
Or I could go whole-hog with Zelda, the 10-inch Dob, and really see
Orion. But you know what? I’ve had more
fun with minimalist Tanya than I have had with any visual instrument in many a
long year. More yearning for the simple
astronomy of my youth? Yeah, prob’ly, and for my youth itself, I guess.
Christmas Eve dawned, and after I’d served the
felines their breakfast, I took a critical look at the sky. What did I see? CLEAR
AS A BELL! Why, it was a blue-eyed Christmas miracle! Maybe. While the
dadgum weather channel admitted there’d be “abundant sunshine” during the day, they
were standing pat with “partly cloudy” after sundown. It looked like this year might
be a win visually. But I began to back off my idea of also imaging Orion with a
smartscope.
That was a mite disappointing, since those CRAZY, new robo-scopes
have been a big part of Unk’s amateur astronomy this past year. However,
whether I’m using a SeeStar or big sis Unistellar, nothing is more aggravating
or conducive to indigestion, actual or metaphorical, than drifting clouds. Why
it’s worse than an undigested bit of beef, a blot of mustard, a crumb of
cheese, a fragment of underdone potato. Oh, well. There’ll be plenty of
chances to snap Orion with the smarties in the coming weeks.

Issue #610: Ch-ch-ch-changes!
We preempt your regularly scheduled program… Originally, thisun was gonna be about me, your Old Uncle, turning my SeeStar S50, Suzie, and 10-inch Dob, Zelda, loose on the fall globulars chapter in UAG (“The Urban Astronomer’s Guide,” for the uninitiated). Then, as it sometimes does, everything—well, a couple of things—changed.
Thanks to the kindness of a friend of mine, Jack Estes,
who is also a longtime friend of this here AstroBlog, and an amateur
astronomer/imager extraordinaire, I was able to level up in the
smartscope world. To the tune of Unistellar’s Equinox (the first
iteration as opposed to the new Equinox 2).
“What in pea-turkey is they-at, Unk?” It’s a
smartscope, Skeeter, you might say the smartscope that set the pattern for
what these instruments would be like. Specifically, it is a 4-inch (114mm)
reflector with its secondary replaced by an image sensor. It is made by a
French company, Unistellar, which now offers several rather advanced
smartscopes.
Other specifics? The Unistellar is as above a 114mm
reflecting telescope, one with a focal ratio of f/4, meaning its focal
length comes in at 456mm. Like almost all other smartscopes, it rides on a
one-arm goto fork mount. Other than that? It features a Sony Exmor IMX224
imaging sensor with a field of about ½ degree. Also like her sisters, the
Equinox is powered by a USB-C rechargeable battery and operated via wi-fi with
an app on your smartphone.
That was what I had gleaned from talking to Jack, reading
the manual, and watching cotton-pickin’ YouTube videos. That reading and
watching (and downloading of the iOS app) done, I began anxiously
awaiting the scope’s arrival at Chaos Manor South…
Your impatient old Uncle didn’t have long to wait. In
just a few days, a largish box was on the doorstep of Chaos Manor South, and
your decrepit correspondent had somehow manhandled it into the Sunroom,
traditional staging area for new (or at least new-to-me) telescopes. I went to
work, aided by Wilbur Wright, second in command of our feline detachment.
Being President of the MARC, it was incumbent upon Unk to be
there, natcherly. I told Miss Dorothy, “Guess I’ll try the new telescope when
we get home.” She just laughed.
Indeed, upon our return I was way too tuckered to do anything other than
imbibe a few cold 807s in the company of the cats as we watched silly YouTube
videos. “Tomorrow night, for sure!”
Strangely, the arrival of the Unistellar Equinox had
coincided with a short span of cool and clear evenings. Only downer? There
would be a fat Full Moon on the rise. I hoped to get in a few minutes
with the Unistellar before Luna got too high. While Jack had provided me with
some instructions to get me started beyond what was in the manual (typical of
today’s manuals) and on the Unistellar website, I still felt like I was flying
by the seat of my pants when I headed for the backyard with this sizable smartscope
(still very manageable for Unk, nevertheless, at about 20 pounds).
Out in the back forty in my customary spot adjacent to the
deck, I got the scope mounted on the tripod—by means of lowering its base into
the custom-style head and fastening a couple of retaining bolts. Now to wait
for darkness, which, thankfully, is arriving at a decent hour now that that
dadgum DST has been turned off. Standing there in the gloaming, I had to admit
the Equinox looked impressive—and a lot more “telescopey” than the oddly shaped
(sorry, girl) Suzie.
When darkness fell, I finally got started. First step was powering up the Equinox via a pushbutton switch not unlike that on the SeeStar. Scope on and button illuminated a purplish hue, I connected to the scope with the Unistellar app for the first time. Now, I relied on what Jack told me to do in his quick start instructions, beginning with leveling the tripod, which I did in rather hurried fashion. Your jaded old Uncle had to admit he was now right excited about this 4-inch telescope.
Hokay, the app said I was connected to the scope, so this
was rubber-hits-road. Next step would be moving the OTA to an altitude of about
45 degrees. After a bit of fumbling around to figure out Unistellar’s onscreen
joystick trope, I got the tube pointed at said 45 degrees. Hell, y’all, I even
remembered to remove the aperture cover! I gotta tell you I was heartened by
the sounds the Equinox made as I slewed her. None of that old-timey Meade-style
weasels with tuberculosis noise. The sound emitted by her altitude motor
was sure and steady.
Next up? Time to do what Unistellar calls “orientation.”
What I call it is a “plate solve.” Mash the appropriate button on the app, and
the Equinox takes pictures and figures out where it is from the star field. It
seemed to me this worked—near as I could tell from what the app said. Before trying
a goto, however, I would need to take a manual dark frame, which Unistellar
refers to as a “sensor calibration.” I might have figured that out on my own eventually,
I reckon, but thank goodness I had Jack’s quick-start instructions.
The Equinox does not have automatic focus, so you focus
manually by turning the large knob at the rear end of the tube, which I assume
moves the primary mirror forward and back leaving the secondary (the camera)
undisturbed. While the quick-start instructions Unistellar furnishes advise you
just to focus on a starfield by eye, Jack told me to go whole hog in Bahtinov
mask function.
With only a mite of fumbling, I found Altair in the app’s
object list (the Unistellar app works with lists rather than a star atlas) and
sent the scope there. The Equinox hummed reassuringly, headed in the proper
direction, and soon had Altair in the frame. I centered up a little bit and
installed the Bahtinov mask—a plastic one that is normally stowed attached to
the aperture cover. As Jack had instructed, I used the onscreen live-view
controls to make Altair pretty dim, and focused till the star spikes were
properly spaced. Focus wasn’t far off to begin with, testament to the scope’s
mechanical quality, but I could have done better. I should have zoomed in on
the star a bit, but, yeah, I was excited. I got OK focus.
Now came proof in the pudding time. First light object? I figgered M57 would be it. Nice an’ bright, but also small. I wanted to see what a smartscope with more focal length would do for me. So, having found that magic Ring in the apps list, I sent the Equinox that-a-way, and held my breath…
When the Equinox stopped, there was that glorious ring.
Was it huge on the phone? No. But it was considerably more than the wee spot it
is with the SeeStar. While Suzie’s ring is identifiable, good luck being able
to make out the central star no matter how much you zoom. With the Unistellar,
even unzoomed on the phone screen, I could see the center of the Ring wasn’t dark
and make out there was something else there. Just a bit of zooming/cropping, as
you can see here, delivers that central star detail on the Ring itself. Was I
happy? You betcha.
Alas, wouldn’t you know it? By now the clouds was rolling
in. I did do two other objects in quick succession, M2 and M56. One thing I
noted on both objects? The exposures went quickly with no frames dropped. It’s
normal for the SeeStar to reject a sizable number of due to star trailing. The
Equinox’s tracking was better. In part, that’s attributable to the shorter
4-second exposures, but I suspect the gears are a lot more refined than those
in li’l Suze.
Shorter exposures were not a problem, by the way, thanks to
the Equinox’s sensitive camera. Almost too sensitive if’n you ask me. My
single problem at first light was blowing out the cores of globs (as you can
see, M57 is also somewhat overexposed. I didn’t have a clue about settings for
exposures on this first night. Ah, well, NEXT TIME. And rest assured, you will learn a lot more about this amazing telescope in the future. And with that, Evie’s first
light night with me had come and gone.
Evie? As you well know, all my scopes tell me
their names. For some reason, I thought that would take a while with this one.
Nope. As we were headed back to Chaos Manor South’s den for cold 807s and TV
with the felines, the girl said,
“Hey, y’all! I’m Evie! Unk, are we gonna be friends?”
“We sure are Evie, we sure are!”
But I said changes, and I meant more than one.
The arrival of Evie was just the first change at smartscope-crazy Chaos Manor
South! I soon learned I’d got the assignment for the Sky & Telescope
Test Report on ZWO’s new smartscope, the S30. You’ll learn all
about it in a coming issue of S&T. Stay tuned…Note that the Equinox saves photos both in this format and standard presentation.
Next Time: As
has long been the tradition ‘round Chaos Manor South and the Little Old
AstroBlog, next month’s entry will appear on Christmas Eve and will maybe
be a mite more sentimental and briefer (well, maybe) than usual. See
y’all then.
Nota Bene Department:
I had a request for the observing list from The Urban Astronomer’s
Guide in computer form the other day. I rummaged around and found that despite
the shutdown of the Yahoogroup that supported UAG with observing planner files,
I’ve still got one. Specifically, it’s in SkyTools 3 format
(which some other planning programs will be able to import). If you’d like a

and I’ll get the file on its way to ya.
