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.
So, Unk, the CGEM, and his (pretty carbon fiber tube) C11 lived happily ever after? For a little while, yeah. The CGEM was indeed just what I’d wanted all along. A GEM with a NexStar HC, a dual Losmandy-Vixen saddle, and all that vaunted NexStar goto accuracy. It was nothing for it to put objects dead center in the field with the C11 at f/10. That honeymoon went on for a while, with a couple of outstanding star party expeditions with the CGEM, but by 2017 the blush was decidedly off the rose.

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.

Only one thing deterred me: I’d have to learn a new goto computer system, the Gemini 2 by Rene Gorlich. Luckily, Rene, who’s had Gemini going for 25 years now, had and has an excellent webpage that makes it easy to get an idea of what Gemini is and how to use it. It even includes an HC simulator that I found incredibly valuable. By the time I got the mount, I was able to use the goto system with only a few hiccups.

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.
“But how about imaging, Unk?” The mount did well with both my SCT and my APO refractors. In particular, I was thrilled with how easy picture taking was with the 811 at one Deep South Star Gaze. I can’t give you a figure on guiding errors—it’s been a long time since I’ve taken pictures with the mount—but I’m pretty sure it guided at 1 arc second or better (and I never did get around to training its PPEC).

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.

Three years later in 2019, was the beginning of the end for the Ningbo bunch. Optronics (Orion) filed suit in federal court against Meade’s owner claiming price fixing and suppression of competition. It’s all a little confusing, but best I can tell, given the convoluted nature of Chinese corporations, Ningbo = Synta (Celestron). Be that as it may, the judge awarded Optronics 16.8 million. How much of that was paid, I don’t know, but in the end Optronics wound up owning what was left of Meade in 2021.

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…

Orion’s story is much the same as that of Meade. It was a little California company founded on a kitchen table (in 1975) by someone interested in astronomy, in this case, Tim Gieseler of Santa Cruz. The company was originally known as Gieseler Electronics due to his first popular products being the “AccuTrack” drive correctors for the AC telescope clock drives of the day. Before long, Tim’s company became “Optronics Technologies,” and finally “Orion Telescope and Binocular Center.”

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.

NGC 2419
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.

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
I’ll begin with February (the nasty January WX prevented me from getting a telescope into the backyard last month even though I wanted to). How will I observe these wonders? I suspect as nice (warmer) weather comes in, I’ll do some visual looking and sketching, but I will begin with the two Smartscopes, Suzie, the See Star S50; and Evie, the Unistellar Equinox.

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
With Suzie the SeeStar, there was the good and the bad with this outing. The good? The app really is to the point where all I had to do was turn on the scope, attach her dewshield, and turn on her dew heater. Everything else is automated. Pick a target on the star atlas, she goes to the field, aligns, focuses, and gets to work. The not-so-good? For many of these objects, the longer focal length of 114mm aperture Evie took the gold ring.

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
In the smartscopes? Make that scope. When I tried to shoot M46 with Suze, the cluster was in the trees. Luckily, I’d got it with Evie the night before. There’s a bit of a gradient from a neighbor’s porch light, but the Unistellar did a fine job with the planetary nebula, which is a striking green with red tinges. Yay, Evie!

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
At 48”, it’s difficult to get past the fuzzball stage with shorter focal length telescopes. And a fuzzball is what I got with Suze, a small, bright green fuzzball. Evie?  Better, but only marginally better. You know what, though? I believe that was more about me than her. I’m still learning the ins and outs of setting exposure, etc. with the Unistellar, and think there might have been some internal detail visible in the Eskimo if I hadn’t overexposed the center. Well, next time, y’all!

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...
I don’t mean “where” as in “location.” I know where they are, they are in the backyards of a lot of imagers old and new. No, muchachos, I’m a-talking about where I stand with smartscopes and what their manufacturers are up to…

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 onemaybe…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.
Moi?
One of those above-mentioned assignments was a Sky & Telescope Test Report on the ZWO SeeStar S30 smartscope. What did I think? I thought—well, you’ll have to wait for an upcoming issue of Sky & Telescope to find out exactly what I thought. But I will say this: the tiny 30mm APO amazed me. How? It allowed me to (easily) take images of legendarily faint nebulae from my backyard. Ones I didn’t think were doable from Chaos Manor South. Objects like the Heart and Soul Nebulae, The California Nebula, The Flaming Star Nebula, and the Horsehead. Scary dim ones like that. All fell before the S30 as dry leaves before the wild hurricane fly.

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
Unistellar divides their five smartscope offerings into two classes, the Expert range and the Odyssey range. The former containing the new Equinox 2 and the Evscope 2 (which possesses an electronic eyepiece). The latter, their Odyssey, Odyssey Pro, and an Odyssey with a red tube and mount. They are all similar, though, with the big difference being the Odysseys have 85mm mirrors while the Experts are equipped with 114mm primaries (all the scopes are reflectors).

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.
So, is the sum greater than the parts? Based on what I’ve seen and heard thus far, “yes.” The Origin appears to work well and produce impressive photos. But… Yes, there’s that dadgum “but.” The price, $4000, seems a trifle much for an altazimuth-only (currently) mounting, and a fairly low-resolution 6.7-megapixel camera.

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...
Muchachos, your old Uncle had been keeping a weather eye peeled—literally. The forecasts for Christmas Eve had been gyrating wildly: “clear” to “partly cloudy” to “mostly cloudy.”  Then, back to “clear,” but segueing to “RAIN” as the 24th of December approached. So what? If you’re a veteran reader of the Little Old Blog from Possum Swamp, you’ll recall one of my yearly astronomy rituals is taking a Christmas Eve peep at that most numinous of ornaments, Messier 42, usually in as simple a fashion as possible.

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.

So, the cats fed, Unk settled in on Christmas Eve morning. I puttered around in somewhat dispirited fashion. Miss Dorothy was away—a dear friend had suffered a fall just before Christmas and D., who is renowned far and wide for her kindness, was staying with her to help. Maybe this Christmas Eve would be a little too quiet. Dorothy would be home for Christmas Day, but the felines and I would be on our own on the 24th. 

How would I pass this Christmas Eve? Aside from the hoped-for observation of M42, there was a stack of DVDs laid out on the coffee table including, of course, A Charlie Brown Christmas. There were also Sherlock Holmes movies and the Christmas episode of the old, old, Ronald Howard TV show. For me, those cozy rooms in Baker Street are the very essence of Christmas. And, naturally, there'd be a dram or two of Rebel Yell... 

So, Thomas Aquinas, Chaos Manor South's Resident Black Cat, and I sat on the couch and watched the antics of the Peanuts gang (which for some reason threatened to bring a tear to my eye this year) and the adventures of that greatest of detectives. Tommy and I waited as we always do for the magical hour, 8pm, when The Hunter would be high enough to fool with. 

Tommy and I watched television as the night wore on, and 8pm came and went. I won't say we dozed, but almost. Then, your uncle started awake, or at least more awake and realized the time had come. Out into the night I went to little Tanya. It wasn't too cold but, man was it damp; I hoped the little scope's secondary or maybe even primary hadn't dewed up--I'd left her aperture cover off--but no. On went her red dot finder. Over to Rigel to focus, back to the sword...and there it was!

Shining as it has shined for me all these Christmases, was the deep sky marvel of the North. Have I seen it better? Sure, I have. But it nevertheless shone bravely through the suburban light pollution, and the more I looked the more beautiful it became. Satisfied for the moment, I thought maybe Tanya and I might essay another deep sky object or two, but, no, I didn't want to dislodge that magnificent vision of the Great Nebula from my mind's eye.

Back inside, I asked Tommy if he might want a look. Some years, when we were both much younger, I've held the feline up to the eyepiece and let him drink in wonder. But no, a stretch and a barely opened eye told me he was in for the night. And soon, so was I...

MERRY CHRISTMAS, EVERYBODY!

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.

What was inside that box? An attractive and light—but not too light—and sturdy tripod. With the legs fully extended, it was a smidge over four feet in height; ‘bout the same as my Manfrotto. And there was the telescope herself, a pretty, two-toned black and gray thing on her one-arm-bandit mount. Finally, there was a small box of accessories that contained a charger, some extra knob-headed bolts (for the tripod I presumed), and a set of Allen wrenches for collimation. All in all, Unistellar’s box/presentation reminded me of what Apple might do if they sold telescopes. The lid of the inner box was emblazoned with the words, “Prepare to be Amazed.” We’d see, I reckoned.

Hot dog! New telescope (are there any sweeter words than those?)! I’d get her into the backyard and get ready to go! Not so fast, Unk, not so fast. In the excitement, your silly Old Uncle had forgot this was the evening of the Mobile Amateur Radio Club’s yearly TNXgiving Potluck dinner party with our sister club, the Deep South Amateur Radio Club. 

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!

Note that the Equinox saves photos both in this format and standard presentation.
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…

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 copy, shoot me an email at rodmollise@southalabama.edu and I’ll get the file on its way to ya.
