Uncle Rod's Astro Blog

Muchachos, I am not over the hill yet. Not quite, but, as I’ve said before, I am getting there. I am entering in on that stage of life when most of us begin tallying up the score and thinking about the big questions:  “Is this all there is?” “Is the Universe more than just a big machine, albeit one with a few funny gears?” “Was there a ‘why’ to me being here?” “Is there a ‘why’ to the Universe itself?”

Actually, I believe I began considering such things four years ago. The questions just weren't quite clear to me yet. Four years ago, as I worked the Herschel Project, my quest to observe all 2500 Herschel deep sky objects, I found my main interest often wasn’t in the H-objects themselves, but in the dim sprites sprinkled across my fields, the tiny and distant background galaxies, the PGCs and the UGCs. I became somewhat obsessed with seeing what lay beyond the friendly old NGC/IC.

So, what does paragraph one have to do with paragraph two? You can’t begin to formulate answers—your personal answers—to the sorts of metaphysical questions I’ve begun to ask without grounding yourself. You can’t begin to know a little about your relationship to the Universe without, yep, knowing a little about the Universe itself. In other words, seeing the Universe might help me place myself in it. I hadn’t yet consciously realized that four years ago, but the wheels were beginning to turn.

Now, I am not sitting around constantly thinking Deep Thoughts. I have done a lot of that lately, but life goes on. Part of life, an important part for me, is astronomy, and one of the ways I like to practice that is by running down to that southern deep sky haven, the Chiefland Astronomy Village occasionally. When I am on the dark CAV field, I want to hit the deep sky as hard as I can, and to do that I need WORK, a project, a list. What would that be for my February dark run?

As I mentioned last time, post H-Project I’ve tried-on several observing programs. Most of them have been fun, and some of them are still being worked. Unfortunately, given my current mind-set, none seemed a good fit for this particular Chiefland expedition. I was somewhat dismayed to discover there was nothing I was fired up about seeing. I wasn’t ready to abandon my CAV vacation, though, so I did some more of that Deep Thinking.

The answer to “What will I look at?” wasn’t long in coming, but it was different from most of what I’ve done before. Not to mention maybe being grandiose to the point of smacking of hubris: I would observe as many quasars as I could see with my Schmidt Cassegrain telescope.

“Quasars?” Yep, quasi-stellar radio sources (or, since not all are strong radio sources, quasi-stellar objects, “QSOs,” if you prefer). These are the frighteningly distant objects that baffled the astronomers of the 1960s, and weren't satisfactorily explained, really, till the era of the Hubble Space Telescope. Yes, they had been presumed to be the violently active black-hole-fueled nuclei of ancient galaxies for some time, but it wasn’t until the HST was able to resolve the host galaxies of many of them that that truth (notwithstanding the theories of the late Chip Arp) became certain.

How is this different from what I’ve done before? When it comes to the deep sky, I’ve always been after details. The Quasars would be like the PGCs, however—just moreso. There would be no detail to be seen in them. They are, as their name says, just star-like points out in the dark.

Where does the “hubris” come in? Quasars aren't just far away; they are cosmic relics. Leftover features of a young Universe. Their distances are measured in billions, not millions, of parsecs. The brightest of them, Virgo’s 3C 273 is close to magnitude 13, and they go all the way down from there. The saving grace? That quasars are star-like. You can see a 16th magnitude star a lot more easily than a 16th magnitude extended object.

First things first. I would need a list of quasars to observe. I turned to SkyTools 3 as I usually do, set up a search on Quasars, hit the “go” button and—whoa—I’d have to do some paring down. While there are “only” several hundred known quasars, SkyTools also fetched similar AGN (active galactic nuclei) objects like Seyfert galaxies and BL Lac objects. Which was cool, but even when I limited the search to the declinations I can observe, there was a large number of objects on my spreadsheet. Next step was eliminating the too-dim ones.

The question then became, “How dim is too dim for my C11 and Mallincam Xtreme?” That deep sky video camera can go amazingly deep—small 17th magnitude galaxies are easy. On the other hand, I didn't want a wearyingly long list. Every whole number increase in magnitude brings a tremendous increase in object numbers, so I backed off  from my original magnitude limit of 17 to 16. That left me with a list of 350 Quasars and their near kin. All of which were very far away indeed, which was the point.

Me + SCT + Mallincam + ST3 observing list sounds like a pretty normal CAV run, even if the objects I’d be running after would be different. There would be one major change this time, however: no motel. I was tired of Chiefland’s two inns, the Days Inn and Quality Inn. Or I thought I was. They are bearable, but distinctly second rate. Since Dorothy wouldn’t be with me this time—she’d be off on a trip of her own to visit her daughter the following week and needed to get ready for that—I decided to avoid them. If D. wasn’t with me, I was loath to spend a couple of hundred bucks in a motel I didn’t much like.

Yeah, I know, I know, after the horribly hot Chiefland Spring Picnic of May 2002, I swore I’d never tent-camp on the observing field again, but I rethought that. Most importantly, it sure wouldn’t be hot, even in Chiefland, Florida, in February. The weather goobs were predicting record lows as low as the mid-twenties. Secondly, a large part of my problem in ‘02 was my tent, a small one. That, I’ve discovered, is a big, huge no-no. If you cannot stand up in your tent, you will not be happy with your accommodations for more than one night, I guarantee. Also, having your sleeping bag on the ground, even on an air mattress, is no way to roll.

Those caveats in mind, Dorothy and I did a recon of Wally-World’s sporting goods section. We returned home with a decent Coleman tent, one with a max height of 6-feet, tall enough for me to stand up straight in. I also glommed onto a camp cot, which I much prefer to a freaking air mattress. Neither tent nor cot was expensive—I wasn’t going on an expedition to Everest—and it warmed the cockles of me little heart to think how inexpensive this Chiefland trip would be with no motel and with gas prices lower than we've seen in years.

Rod ain’t no dummy (well, not always); back home, I set the tent up in the backyard to make sure I could get it pitched easily and quickly on the first night with dark arriving early. Coleman claimed my new cabin tent was an “instant up,” and while it might not be that quick to set up, amazingly, I had it pitched, by myself, in about five-minutes, no foolin’. Camping gear acquired and checked, all that remained was to wait the few days till my Thursday morning departure.

Anyhoo, Wednesday afternoon, the day before my leave-taking, I loaded up the 4Runner. For various reasons that had nothing to do with the CAV or the observing I hoped to do there, I wasn't looking forward to the trip as much as I usually do. One of those reasons was that Dorothy wouldn’t be with me. I’ve been down a time or two without her over the years since she started accompanying me, and I’ve found it’s just not as much fun without her as with her. Not hardly.

Frankly, when I took a look at the weather forecast for Chiefland on Wunderground, which was predicting horrendous cold—for us southern tenderfoots—in the mid - low twenties, I was tempted to just call the whole thing off. I didn't, however; mostly because a gentleman was to meet me out on the field to buy my cast-off NexStar 11 items:  the fork, tripod, case, and wedge I had left over after I deforked Bertha. He’d responded to my Astromart ad, I’d promised I’d be at the CAV, and I didn’t think fierce cold should be enough to prevent that.

Dorothy was, naturally, skeptical about my tent camping scheme in such frigid conditions, but I had an ace up my sleeve. My Black Cat catalytic heater ought to be safe enough to use in the Coleman as long as I kept a few of the tent’s vents open. The heater doesn't produce an open flame; the major safety consideration is that it, naturally, uses up oxygen. Black Cat in the tent or under the EZ Up as needed, and I figgered I might survive the low twenties.

Wednesday evening was pleasant enough, with me turning in not long after Arrow went off. I still wasn’t as excited as I usually am on Chiefland Eve, but so what? I’d go through the motions anyway; sometimes that is enough to get me back on track. In addition to selling my astro-stuff, there were quasars to chase and my “new” C11 to check out. I’d only had the CGEM out in the backyard twice, hardly enough to give it a real shakedown.

The trip down was as uneventful as uneventful can be. I’d normally have been listening to music on the satellite radio, but without Dorothy to talk to and just music on the stereo, I thought my mind might be apt to turn down pathways I didn't want it to turn down. Instead, I had a massive audio book, Stephen King’s Doctor Sleep, the sequel to The Shining, which I'd been meaning to listen to or read for months and months.

Thanks to Mr. King’s Grand Guignol tale, the drive east to Tallahassee on I-10 didn't seem overly long, and I was soon turning off at the well-remembered exit, refueling at the Sunoco station, and picking up Highway 19, the Florida – Georgia Parkway, gateway to the Nature Coast and points south.

It seemed odd to drive right past the Days Inn and Quality Inn, and I nearly stopped at the latter. The forecast I’d looked at on my phone at the filling station was now predicting even colder weather. But, no, I’d stick to my plan and at least try tent camping. If it was too much, I’d get in the truck, drive back to town, and check into one of the motels no matter how late the hour.

I was pleased to find a handful of hardcore Chiefland Observers including my friend Paul Lavoie (with his beautiful A-P mount and refractor) on the field Thursday despite the dire prognostications of the weatherman, and I began setup feeling better than I had all day.

The CGEM mount is not much harder to assemble than my VX. Oh, the head is heavy enough, but it’s nowhere near as heavy as the old fork/OTA combo was. Not that the C11 tube is a lightweight, even without the fork. And you have to slide the dovetail into the saddle from one end, not tip it in like a Vixen dovetail. But it really wasn’t that difficult, and since I’d have it up for two or possibly three days, no prob. One thing was sure; the old girl looked good on her new mount.

Two or three days? Don’t I normally stay through Sunday morning? I usually do, but, again, I wasn't in the mood this time. I thought that as soon as the NexStar GPS stuff deal was done on Saturday, I would turn the 4Runner, the ever-faithful Miss Lucille Van Pelt, for the Swamp and home. Foregoing Saturday night would to some extent depend on how much observing I got done Thursday and Friday, but it looked to me as if Saturday would be a weak night, with poor transparency probable, scattered clouds likely, and considerable overcast possible.

Scope on mount and EZ Up erected, it was time to get to something that had been worrying me:  the tent. Sure, I’d set it up in the backyard, but I was far from home now and darkness wouldn’t be long in coming. That situation is always an invitation for Mr. Murphy and Mr. Finagle to come calling. I needn't have worried. I was tired from the drive down, and it took me twice as long to get the tent pitched as it had at home, but that was still only 10-minutes. What had taken the longest was getting a big tarp, the ground cover for the Coleman to go on, laid-out and staked down. There were frequent gusts of frigid wind and the tarp almost got away from me a time or two.

All that remained was to tie-wrap three tarps to the EZ Up to form its sides and get the computer and Mallincam Xtreme ready. I decided to take a break at this juncture, however, and make my supper/Walmart run. At Wally-World, I confined my purchases to an inexpensive extension cord (forgot one), bottled water, and snack items.

Supper? BBQ Bill’s was tempting, but it wouldn’t have been fun without Dorothy, and I didn't want to waste time waiting to be served in a real restaurant with work still to do on the field. I settled for Taco Bell’s notorious and delicious Dorito Taco Big Box. Scarfed that down and hurried back to the CAV.

Got the tarps on the canopy without much trouble despite the wind, which wasn’t dying down, and proceeded to mount the camera on the scope's rear cell and hook it to the laptop and to my monitor and Orion DVR. Yes, I am still using the little digital video recorder I bought toward the end of the Herschel Project. I tried running the Mallincam's video to the computer via a frame grabber for a while, but didn't like working that way. I do control the Mallincam with a laptop, but the video goes to either my monitor (my old portable DVD player) or the DVR via a composite video switch box.

It was then that I realized I'd left an important but not critical piece of gear at home, my JMI Motofocus. I’d been in such a mood that I hadn't followed my gear-loading checklist as attentively as I should have. I did video for years without a Motofocus, however, and I could get by without it, but there was no denying I’d miss the widget—a lot.

I was darned tuckered by the time I finished the last of the afternoon’s preparations—setting up the tent hadn’t been that much additional work, but it sure felt like it. I am of the opinion that the next time I do a tent on the observing field in the winter, I will try for an earlier departure from home. Nothing is worse than scrambling around trying to get everything ready with dark coming.

The good thing, I reckon, was that by the time my preparations were done sunset had arrived, and I didn't have to sit around waiting. Polaris was soon popping out and shortly thereafter, bright alignment stars. I essayed a 2+4 goto alignment, an AllStar Polar Alignment, and a second 2+4 to ensure goto would be dead-on after moving the mount in altitude and azimuth to polar align.

All went sweetly easy. Just like with the VX. I operated the CGEM with NexRemote using a Logitech Wireless Wingman gamepad as my “hand control,” and centered the stars with the video camera, which can be set to display a set of cross-hairs on the video screen. Easy as pie, and my test goto to M79, Lepus’ little globular cluster, put the target dead center on the screen. We were off to the races.

The only question was which races we’d be off to. I was tired and already feeling cold despite my coat, sweatshirt, long sleeve shirt, and long johns. I had the suspicion I wasn't up to chasing dim quasars on the first night. Might be best to spend the evening checking out the new scope/mount combo and seeing if I still knew how to work the Mallincam Xtreme after not using it for months.

The CGEM performed superbly. I was working with a small field of view, but any object I requested, from one horizon to the other, was always in the camera’s narrow field—which was smaller than it was when the scope was in its fork configuration.

Since I didn’t have to use a diagonal with the scope on the CGEM (had to with the fork or the camera would bump into the drive-base), I didn't have enough spacing between the Xtreme and my Meade f/3.3 reducer to provide much focal reduction. With the Mallincam inserted into a visual back screwed directly onto the reducer, I got maybe f/4 – f/5. Field looked to be maybe 10’ x 20’. I’ve got some spacer rings and an SCT prime focus adapter I can use to get a wider field next time.

There was actually some benefit to the smaller field, though; I was getting big, detailed pictures of objects. The famous edge-on galaxy in Andromeda, NGC 891, just slammed onto my monitor, showing mucho detail in its equatorial dust lane. In fact, every object I looked at Thursday was superb. There was a reason for that that had nothing to do with the scope:  a crazy-good sky.

Shortly after NGC 891 was in the can, I stuck my head out from under the tent canopy and looked up. “Well, darn…looks like haze moving in.” Venus in the west was set against a hazy background that spiked upwards towards the zenith. Then it hit me:  “That ain’t haze (you dummy), that’s the Zodiacal Light!” When conditions are right, the CAV skies can still amaze.

Unfortunately this crazy-good transparency was accompanied by crazy-bad temperatures that began dropping sharply at mid evening. They had hovered on in the upper 30s for some time, but as nine p.m. approached, the low thirties arrived and I guessed the mercury would not stop falling anytime soon.

I placed the heater in the tent to warm up my accommodations, since I believed it wouldn't be long before Big Switch Time. I was tired, I was cold, and I was not my usual ebullient self. I did a few more goodies including the Horsehead Nebula, M78 (which was as good as I’ve ever seen it on video), M81, M82, and several more before bowing to the inevitable.

Or starting to bow. I was here to get quasars, and I would get at least one on this night. Which one? “Old Faithful,” the Twin Quasar, QSO 0957+561, in Ursa Major was decently high so I went there. One of the best things about this magnitude 17.0 object (so SkyTools says; I believe it may be as much as a magnitude brighter) is that it’s easy to track down. It’s close to a bright galaxy, NGC 3079, and a dimmer galaxy that’s still easy in the Mallincam, MCG 9-17-0 (magnitude 15.4). Best of all it is adjacent to a distinctive pattern of field stars.

When the CGEM stopped, I immediately picked out those stars in a 30-second exposure. I thought I might be seeing the QSO too, but the interests of being sure I upped the exposure to 1-minute. Yep. There it was. A little pinprick of light. Not much different from what it had looked like in the eyepiece of my Dobsonian when Dorothy and I were at the 1999 Texas Star Party. Or…maybe it was different.

As its name suggests, the Twin Quasar consists of two QSOs positioned next to each other, a brighter one and a slightly dimmer one separated by 6-arc seconds. Except there aren't really two quasars there; the two are the same QSO. A massive foreground galaxy, YGKOW G1, is creating a gravitational lensing effect, causing an additional image of a single object to be formed. Peering closely at the monitor, I was thunderstruck to realize I was resolving the Twin. Its "ghost" image was surprisingly easy, actually.

The Twin’s stats are amazing (and kinda scary). The light from the core of this ancient galaxy, which is nearly 8-billion light-years from us, set out before the birth of the Solar System. Most amazingly, I was seeing it with my modest telescope and my modest camera in a relatively modest sky. That was almost enough to impel me to push on no matter how cold I was. But not quite. I threw that accursed switch, covered Bertha, and headed for the Coleman.

Surprisingly, the tent felt almost too warm at first. I got my heavy coat off, set up the PC on the camp table, inserted the DVD of Aliens, poured out several finger of Rebel Yell, and was warm and cozy for quite some time. Eventually, the outside temperature dropped enough that the little heater couldn’t keep up, and I decided my sleeping bag was a good idea, but it was never tremendously cold in the tent.

That wasn’t the problem. The problem came just after dawn when I needed to use the facilities. Nature’s call impelled me to brave temps that my phone claimed had dropped to freaking 19, which must be close to a record for this part of Florida. I got to the clubhouse only to find the toilets were frozen up. There’s a heater to prevent that from happening, but we were all so fixated on the fantastic sky that we forgot to turn it on.

I ruminated on what to do. I’d like to use the bathroom, and there was also the matter of the (open to the sky) showers. I didn't believe it would be warm enough even in the afternoon to encourage me to take one. Solution? Jumped into the 4Runner and made tracks to the Quality Inn.

There, it eventuated that a room for Friday would not be a problem, but one for Saturday would be. There was a big funeral being held in town and both the Quality Inn and Days Inn were booked up. I figured the same would even be the case for the modest Manatee Springs Inn, the town’s single remaining hostelry. I told the clerk I’d take the room for one night. Sounded as if my decision about staying/going on Saturday had been made for me. I doubted I'd want to move back to the tent after enjoying the hot shower, breakfast, and cable TV of the motel.

Late Friday afternoon, refreshed, I motored back to the field for what it appeared would be the last night of my dark run. If it were to be that, I needed to get as much done as I could. After viewing that one quasar Thursday, I’d got a good feeling about the new project and thought a magazine article might come out of it. Maybe even more than that. So, I needed to see as many QSOs as I could on this evening. I could no doubt get quasars from the club dark site back home with the uber-sensitive Mallincam, but I knew they’d still be easier in Chiefland.

Once again, the CGEM and C11 performed admirably. You hear a lot of grumbling about the mount—there’s no denying it had a somewhat bumpy introduction—but I am here to tell you that if your requirements are similar to mine you will love it. For visual/video with an 11-inch or smaller SCT it is unbeatable for the price. Is it an A-P Mach 1? Of course not. But I don’t need such a thing, you might not either, and you may be surprised to hear that, despite what’s sometimes said about the mount on Astro-BBSes like Cloudy Nights, the CGEM is capable of doing deep sky imaging. Long exposure, guided, prime focus imaging.

Will I use the CGEM all the time? No. It’s heavy, and the combo of the VX mount and Edge 800 SCT (or one of my APO refractors) has proven to be a powerful one for me. It’s just so easy to get into the yard or the observing field, and the gears and motors of the VX are a step up from those of earlier mounts like the CG5 and, yes, the CGEM, in my opinion. Still, there are times when I want the horsepower Big Bertha can bring to bear. The CGEM is allowing me to continue to use her, and I didn't pay a lot for that privilege.

The night’s observing? It was like doing the Herschel Project, just a little harder. I’d issue a goto command with SkyTools 3, which was connected to the mount through NexRemote’s virtual port feature (no QSOs in the NexStar HC database). The mount would make her sounds, which I gotta say are a little more like the weasels-with-tuberculosis noise of the old CG5 than the more refined hum of the VX, and when she stopped I’d take a look at the video monitor. That’s where things got a little “interesting.”

Before I could get going good, however, I had to deal with a bad video cable. I’d had several incidents Thursday where the video glitched. Wiggling the cable always brought it back. Friday night, no matter how much I wiggled I couldn’t restore the picture. Luckily, I had a spare cable, which cured the problem. The fault was really mine; I knew I had a bad Xtreme cable and a good one, but it had been so long since I’d used the camera that I’d forgot which was which. If I’d been smart, I would have trashed the bad cable just as soon as I received a new one from Jack Huerkamp, but you know how I am about throwing anything away.

When I was hunting Herschels, it came down to deciding which deep sky object on the screen (there were often multiple ones) was the target. That could be trying at times, but usually there weren't enough faint fuzzies to make it a pain. Not so with quasars. They are star-like points. The targets on my list that aren't are a few Seyfert galaxies, which might—might—present disks. What I had to do to identify my targets was match star patterns on the screen with those on a chart or photo.

At first, I was concerned about being able to do that in the field, in the cold, when I was tired. In truth, it wasn't as much of a problem as I'd feared. SkyTools’ excellent charts (POSS plates didn’t seem to be as much help), which were easily sized to the same field dimensions, approximately, as that of the camera, made it as easy as such a thing can be.

One other help? You often hear quasars referred to as “blue point-sources,” but even so, I was amazed to see some actually showed an obvious blue tinge with the Mallincam, which made picking them out substantially easier. Somewhat like when I was doing small Herschel elliptical galaxies and learned to look for their golden hue. Color helps.

So, was it fun? You bet. Surprisingly so. Part of it was the sense of accomplishment. When the run was done, I’d corralled twenty of the suckers (including the Twin Quasar Thursday night). Even more satisfying was thinking how deep I’d gone. The dimmest objects Friday were at my self-imposed magnitude 16 limit. As a sprout, reading what little I could understand in the S&T articles about these weird new objects, would I ever have dreamed I’d easily image down 16th magnitude and push out toward the edge of the visible Universe with my personal telescope? Not hardly, friends, not hardly.

Nineteen objects doesn't sound like a lot of objects for all of Friday night, does it? I considered just trusting the CGEM to make things go faster. Trusting that the object of my desire was somewhere in the field of the camera when the mount stopped, and reviewing the images at home to identify my quasars. The CGEM never, ever missed an object, but I still demurred. I wanted to be sure, and I wanted to say I had seen my objects out on the field. Not seeing them until I got back home just seemed a step too far removed from “amateur astronomy” to me.

What mainly kept my object count down, however, wasn’t the time it took to identify the quasars. After a while, I got pretty good at that. It was the sky. The night was (a little) warmer than Thursday, but it was also not as clear. I was seeing real haze, not the Zodiacal Light. The wind was gusting, too.

Bertha and the CGEM handled the wind remarkably well, no doubt thanks to the TPI spreader on the tripod, but eventually the stars in my exposures began to elongate as strong winds caught the big sail of the C11 dew shield. Not long after that, the sky background on my images (and on Paul’s DSLR images) began to turn brown, a sure sign of haze. Formerly easy 15th and 16th magnitude QSOs suddenly became harder. It was well before midnight, but there was no denying it was time to call it.

Back at the motel, I spent considerable time with the cable TV (my beloved ghost shows) and Rebel Yell. I was feeling good. Better even than Thursday night. Not only had my run been still more successful than Thursday’s, I had a warm room, a warm bed, a hot shower, and the prospect of a hot meal in the morning.

Saturday a.m. after breakfast (scrambled eggs, biscuit—ONE biscuit—and gravy) I checked out and headed to the CAV to pack. Which took a while given that I had to strike the tent and get it back in its bag. I took my time since I knew the fellow who was buying my gear likely wouldn't arrive before noon. That was OK. The additional hours at the CAV after Miss Van Pelt was loaded let me spend some time with my friends and have a leisurely lunch.

Once I turned over the NS11 gear to its new owner just before 2 p.m., however, I was more than ready to skedaddle. A look at the sky, which was now crisscrossed by multiple jet contrails, showed conditions were  unlikely to be better than the previous evening's, and might be considerably worse (a storm front was moving in from the east). I hit the highway, drove straight through with one stop for gas and nothing else, and made it back to the New Manse at 7 p.m. after passing through torrential rain along the Florida Panhandle.

Best Chiefland run ever, Muchachos? Nope. The weather, the cold weather, if nothing else prevented that. The upside was that I did get a couple of things accomplished. I also became reacquainted with how much I love our avocation. I started out not really in the mood to observe, but once I was out on the field with the scope humming, I had a cracking good time. What more can you ask than that?

Next Time:  Star Trek and Me II...

The King is in the building, ladies and gentlemen...

The king of the Solar System, that is, muchachos. Have you had a look at him this apparition? If not, get after it. Jupiter is now rising shortly after 5 p.m. and is high enough—30+-degrees above the horizon—for you to begin observing seriously by 7:30. In addition to being nice and high throughout a large part of the evening, Jupe is well placed along the zodiac in Cancer this year, not too far south, that is.

I’d be heading down to the Chiefland Astronomy Village for the February dark of the Moon run, sucking up deep sky photons with my cameras, but before that, I planned to stay closer to home, a mere 4.8 AUs away from our cozy little rock, out in the realm of the frighteningly magnificent 5th world.

Not that I expected much for my efforts. I mean, come on boys and girls, it’s freaking February. Even down here on the (sometimes) sunny Gulf Coast where we are usually at least a little out of the path of the Jet Stream, the good seeing, the atmospheric steadiness, you need for high resolution planetary imaging or exacting visual work isn't a regular feature of winter.

Despite the likely prospect of a misshapen Jupiter dancing and shimmering in cold winter air, I figured I’d devote last Sunday evening to a little visual scoping out of Jupe to get me back in the mood for planetary work. Being lazy, the telescope I’d use for that would be my beloved Celestron C102 refractor, Amelia. I lugged her and her AZ-4 mount into the backyard at dark. It would be about an hour and a half till my quarry was up high enough to bother with, so to amuse myself while waiting, I thought I’d have a look at Venus low in the west. In went the 8mm Ethos, to the planet we went, and… “Ulp!”

I expected a fair amount of false color, folks. Even at f/10, it’s asking a lot for an achromat to throw up a decent image of Venus at 150x and above. And, yes, there was plenty of the dread color purple. But, you know, it really wouldn’t have been bad if the cotton-picking planet had stayed still. When the atmosphere steadied down occasionally and briefly, a surprisingly sharp gibbous disk was visible. Unfortunately, that didn't happen much. The seeing was, no denying it, as your Uncle likes to say, “punk.”

Just for spits and giggles (this is a family-friendly blog, y’all) I moved the telescope to Sirius. I habitually check the star whenever I have a scope set up to see if I might spy the Pup, the Dog Star’s white dwarf companion. Not a prayer. The story was the same as with Venus. The color wasn't bad, and the star threw up a nice Airy disk and diffraction rings once in a while, but not often. Mostly Sirius was a boiling mess. It began to look as if I'd be wasting my time with Jupiter.

I was still hoping, though. I'd leave the C102 outside for the hour required for Jupe to hit 30-degrees. If he looked as bad then as his sister world had, I’d go back in again, have some drinks and TV, and try again in another hour after that.

Back in the New Manse's cozy den, in addition to surfing the cable channels, I spent some time mulling over (I seem to do an awful lot of that about an awful lot of things lately) my history with Jupiter, our friendly, neighborhood gas giant.

Let’s dispense with me and Jupiter in the 1960s right off the bat. I never did see much of the planet with my 4-inch Palomar Junior reflector. Oh, I loved the shuttling Galilean Moons, and I could make out the north and south equatorial belts, but that was about it. I wanted to see the Great Red Spot bad, but I am not positive I ever even glimpsed it with my little telescope. The truth is that for an inexperienced observer, especially one like li'l Rod who didn't tend to give the planet (or any other object) much eyepiece time before going on to something else, 4-inches ain't much aperture.

The mid-late 1970s should have been better. I had a C8 and was working on my impatient nature, not just regarding astronomy but everything else. The problem for me and Jupiter in the 70s was now that I had a BIG C8 I was deep sky crazy. Having very dark Arkansas skies at my disposal didn't help; I didn't care pea-turkey about boring old Jupiter or any of his Solar System compadres.

Nothing changed, really, till the late 1980s. I was back in the Swamp and living under light polluted skies (not far, interestingly, from the Garden District and the old Chaos Manor South). You can see many deep sky objects from a light-polluted backyard—hell, I wrote a whole book about that a few years ago—and I was going through a period when, for a variety of reasons, I was doing a lot of observing. Those quiet moments under the stars were like a tonic for me.

If there was a Moon in the sky, or it was hazy, or there wasn’t much I wanted to look at deep sky-wise in my badly compromised back 40, I’d turn back to the Solar system, and, especially, to Jupiter when he was on display. Saturn is cool, and will give up some disk detail. Same with Mars. But neither offer the regular wealth of detail Jupiter is capable of showing.

Under good conditions, a C8 can deliver incredible amount of detail on Jupe. Especially if you’ve learned to be patient and keep looking. I had, and the Great Red Spot was no longer a challenge. Two cloud bands? That was just the beginning. This was the stuff I always longed to see, and the irony was that it wasn’t even that hard with just a little more aperture and a little more patience.  In fact, when I kept the patience but gave up the larger aperture, I was still able to see a lot of Jove.  

As my second marriage foundered, it eventuated that I needed to sell my C8. Which was OK; I just wasn’t that distressed about letting it go. As I’ve written before, the Super C8 Plus that replaced my (excellent) Super C8 wasn’t exactly a barnburner. Anyhow, I suddenly found myself back with the freaking Palomar Junior.

I was hoping that, given my better eyepieces and much better skills compared to what I'd had in the late 1960s, the wee scope would show me more of Jupiter than it had when I was a sprout. It did, but not that much more. The truth is that a 6-inch reflector or a 4-inch refractor is just better on Jove. Shortly, I was able to up my game a mite with a 6-inch home brew Dobsonian, and, as expected, the planet got better again. Not C8 better, but better. That old saw, “aperture always wins,” is every bit as true for seeing planetary detail as for seeing dim galaxies.

Still, I was able to pull some detail out with my 6er, as a page of my logbook from that era shows (all my logs from the 60s and 70s were lost, but I still have some from the 80s and early 90s). I usually couldn't see fine detail, not convincingly, with the 6-inch, but I was seeing enough to keep me looking.

Actually, I didn't get my first really good look at the planet until 1994. As I've recounted a time or three, the Saturday of my first date with the wonderful Dorothy, I’d got on the telephone, called Astronomics, and ordered a 12-inch Meade StarFinder Dobsonian, the now-famous “Old Betsy.” She didn’t arrive until the day before we were wed in September, so First Light was understandably delayed. As soon as we got back from our Virginia honeymoon, however, I manhandled the scope’s enormous white Sonotube into Chaos Manor South’s backyard for a look at Jupiter.

Betsy was just an inexpensive Dobsonian, an f/4.8 Dobsonian, so I didn't expect much planetary performance from her, but there was a bright full Moon in the sky and there was Jupiter, so why not? Not only was I not sure of my scope, the planet was getting awfully low in the west. Nevertheless, in went my vaunted Circle T Ortho and…

Oh. My. Freaking. God. There was all the detail Patrick Moore told me (well, in his books) I might see some day. Belts? There were belts and belts and belts and zones and zones and zones. There were loops and whorls of clouds. There were spots. There were Festoons. There was plenty of not very subtle color—blues and browns and yellows and creams. Oh, and red. Or pink, anyhow. Most of all there was the Great Red Spot. It was stark despite its somewhat faded character at the time. Hell, I could glimpse details within the spot.

The 1990s were mostly a deep sky time for me. Those were the years I got back into astrophotography with a new C8, Celeste, I bought in the spring of 1995. Those were also the big star party years, with Dorothy and I taking Old Betsy all the way to the Texas Star Party to view distant wonders. The next decade, however, would bring me back to the Solar System. That was no doubt spurred by all the excitement concerning the 2003 Mars apparition.

Yep, Unk was finally ready for a break from the Great Out There. Suddenly, the planets were fascinating again. Hell, I rejoined ALPO (the Association of Lunar and Planetary Observers, not the dog chow) at the 2003 ALCON in Nashville, and by September I had a hard drive full of mind-blowing Mars pictures thanks to my SAC 7 camera, as I recounted next week. Mars was soon shrinking, but that didn’t mean I was ready to leave the planetary neighborhood. Jupiter would become available as spring 2004 came in. What would the SAC do with him?

It turned out Jupiter was actually easier to image than Mars. Not surprisingly, since the gas giant was larger than Mars had been at its largest. While Jupiter is, maybe surprisingly for a generation raised on those crazy-colorful Voyager images, really a world of low contrast, pastel features, they are still easier to capture than the Martian dark markings. I also found the planet easier to color-balance. It was hard to convince myself Mars should be more a peach color than an angry red, but was always clear what Jupe should look like:  somewhere between the mild cream/brown of the eyepiece and the Technicolor riot of the Voyager shots.

The only diff? Jupiter rotates rapidly enough that too long an .avi sequence will cause blurring when the frames are stacked. But a minute or so coupled with our usually good seeing always got me plenty of frames to play with, even at the pitiful 5 – 15 frames per second the SAC 7 could muster. I was pleased with my Jupiter pix and planned to keep on imaging the planet every time he was in the sky.

That’s what I planned, anyhow. I was even a regular contributor to ALPO for a while, sending in my Jupiter images, good and not so good, like clockwork. That and my love affair with the Solar System continued for three-four years till I heard the call of wild intergalactic space again. 2008 found me finally hitting the Herschel 400 HARD, and the next year saw the birth of the Herschel Project. Moon and planets? Not even on my fraking radar.

Post Herschel Project, I’ve had several observing programs on the drawing board, and a few that even got onto the observing field a time or two, notably The Burnham Project, my quest to observe all the Handbook’s DSOs, and Operation Arp, my tour of Chip Arp’s peculiar galaxies. I’ve also done more deep sky prime focus imaging than I have in a long time. But I’ve also regularly been coming home.

Destination Moon, my tour of the lunar surface has been a lot of fun. And the other night when I was out trying to get some shots of the terminator and happened to look over my shoulder at old Jupe rising in the east, I began to think “It’s planet time again.”

And so it seems to be, which brings us back around to last Sunday night. After an hour, I wandered back out and took another look with the C102 and the 8mm Ethos. The seeing wasn’t that good, but it wasn’t that bad, either. The flattened disk of Jove was reasonably sharp and not swimming too much. There wasn’t a wealth of detail, but the equatorial belts were clearer than they ever were in the old Pal Junior, and the moons were usually pinpoints rather than smeared out blobs.

As I watched, I occasionally began to pick up more. The Polar Regions and some narrower belts began to appear at least.  It was almost enough to make me want to run inside and see if I could find my Wratten 80A filter. But man was the dew heavy. You'd a-thought it was spring already, and the amount of detail the refractor was delivering wasn’t quite enough to make me want to get soaked to the skin. Nevertheless, I wanted to see more of Jupiter again. And I knew how to do that. Or, actually, I knew a couple of ways to do that: with more horsepower and with a camera.

“More horsepower,” more aperture, was what I had in mind for Tuesday night. A front had barreled through, one of the last strong cold fronts of this winter, I hoped, and I didn't think it would be a night for imaging. The Clear Sky Clock (I just can't get myself to call it “Clear Sky Charts”) agreed. I thought I might set a visual scope out, however, and take a few looks at the King during the commercials in The Flash and Agent Carter. Didn't expect much, but I was hoping a bigger scope might do some good on a poor night.

The telescope of the evening was the lightweight Dobsonian Pat made out of my old 8-inch Konus (Synta) Newtonian, Old Yeller. In addition to four times the light gathering power of the 4-inch, the scope would bring much more resolving power too. That was offset by the fact that that an 8-inch mirror would be looking up through a larger column of disturbed air than the C102’s 4-inch objective. Still, I’ve usually found that you eventually see more with more aperture, even on nights when the atmosphere is reluctant to behave.

I gave the scope plenty of time to cool down, several hours, and I gave the planet plenty of time to get away from the eastern horizon. I didn't go back outside until Agent Carter went off at 9 p.m. Inserted a 7mm Uwan eyepiece (142x), put my planet hungry eye to the ocular and saw…

Nuttin’ honey. Well, not quite nothing. There was something, but that something was just a big, white, flattened Ping-Pong ball with two subdued horizontal stripes, the North and South Equatorial Belts. I shouldn't have been surprised; the seeing was even worse than it had been at its worst on Sunday evening. Often a larger scope will show more than a smaller one on nights like this if you wait for those brief moments when the atmosphere steadies down, but I wasn't getting any of those moments. I gave it up as a bad business after a frustrating hour and went back to the Boob Tube.

Wednesday afternoon, I strolled out onto the deck to see what I thought the chances for bringing back decent images might be. The Clear Sky Clock was predicting so-so seeing at best, but it was warm(er), the air was still, and I thought there was a chance I wouldn't be wasting my time with a camera.  

Even if it turned out conditions were not good enough for decent images, I still wouldn’t be wasting my time. I wanted to try out the latest beta release of my favorite planetary image capture program, FireCapture, anyway. I went ahead and set up old Celeste on the VX mount.

Sunset came, and, after that, a few drinks and Arrow. When the show went off, your Uncle somewhat unsteadily headed for the backyard. Everything was ready to go including the laptop on the table on the deck. All I had to do was get the mount goto aligned and polar aligned. I essayed a 2+4 alignment, went on to the AllStar polar alignment (Rigel), and declared myself ready to shoot. I could have done another 2+4 to tighten up goto after the polar alignment, but since I’d be on Jupiter all night, that really didn’t matter. What did matter? Tracking, since I’d be using FireCapture’s ROI feature.

What’s they-at? Rather than shooting a full frame, FireCapture, can shoot a cropped area just large enough to contain a planet (you select your planet from a drop-down menu), the “Region of Interest.” By downsizing the frame to just what’s needed to fit a planet, FireCapture can get the frame rate up, doubling the ZWO ASI120MC camera’s speed from a hair over 30 fps to 70 fps. “More frames” is always good when shooting planets. Especially on a night like this one when it appeared the seeing would start out average and get worse.

The problem, if there is one, when using the ROI feature? Your mount has to be tracking well enough to keep the planet in a very small field for the duration of the exposure. That was not a problem with the VX. Even at f/20 with the C8, I only had to adjust the mount’s aim occasionally; it was easy as pie to get 1-minute (and longer) .avi sequences. I gotta tell you, folks, the humble Celestron mount continues to amaze me with its inexpensive goodness.

Anyhow, I centered Jupiter in the flip mirror on the back of the C8—a flip mirror is necessary for high resolution/large image scale planetary photography if you want to keep your hairline intact—and cranked up FireCapture 2.4. What’s new in the beta? Most noticeably, a completely redone and modernized user interface with a control window separate from the preview window. Other than the fancy new GUI, I was pleased to see everything worked purty much as it always has—which is “very well.”

How was the planet looking? When I got Jupiter focused up with the JMI motofocus, I had to admit “not too shabby.” Oh, it wasn’t like it can be on those rock-steady spring nights when it just sits there, maybe wavering/fluttering a little every once in a while. Still, not bad. Watching the preview frames flying by, I could make out more than just the two main cloud belts. 

I sat out there on the deck in the chilly but not cold air for the next hour or so firing off .avi sequences of the Big Boy. I tried to get about 2000 frames every time, which took around 30-seconds - 1-minute depending on my exposure settings. As always, I aimed for a Jupiter that looked just slightly underexposed to my eye. Most of the time, I thought I was getting OK data, but as nine p.m. approached, I could tell, ironically, that the seeing was degrading. Why ironically? Because it was just as the planet was getting nice and high that the atmosphere went totally to hell.

I shut down, gathered up the laptop, and left the scope set up under a Desert Storm cover in case I wanted to give it another go Thursday night. That would depend both on my results when I processed Wednesday evening's sequences and what the weather did. Thursday was predicted to be about the same as Wednesday seeing-wise. Unfortunately, that prediction turned out to be wrong, and another blasted cold front came roaring through Thursday afternoon, scotching the idea of more imaging.  

Processing the Thursday morning was surprisingly easy; the data I got was considerably better than I thought it would be. Stacked the frames of the .avi files with Registax 6 (and AutoStakkert, which I am learning to use), applied the program’s amazing wavelet filters, did a little tweaking in Photoshop, and that was all it took, muchachos. Hell, not bad, not bad at all. Which just goes to show the truth of that old saw, “Nothing ventured, nothing gained.” It would have been easy to plunk myself down in front of the television Wednesday evening and stay there. Sure am glad I didn't.

Next Time:  Down Chiefland Way…

Note:  I’ve been informed that long-time astro-businessman Jeff Goldstein of AstroGizmos has passed away. I’d just seen Jeff at the 2014 Deep South Regional Stargaze, and, once again, having a source of those little things, from batteries to dew heaters, that you unexpectedly need at a star party came in so handy. Jeff was friendly and helpful and will be missed. I have not heard whether the business will continue…

What would be the subject of this week’s blog? That was kinda hard. I have not, as I feared when I took this weekly, run out of things to say, muchachos, but sometimes a topic doesn't immediately suggest itself. Those “sometimes” usually being the times when not much is going on around here astronomically.

Following my last minute comet-save recounted last week, I thought I’d so some Moon pictures for another installment of my Destination Moon project. I still had the C11, Big Bertha, set up in the backyard following my abortive try for asteroid 2004 BL86. Alas, the seeing was just not good enough. Even given my humble standards, not a single image was usable. OK, I’d back off to a more forgiving C8 the next evening. Nope. The .avis I got with my 8-incher, Celeste, were better but not better enough. Into the recycle bin they went.

Should I go RSpecing again? I’ve promised myself I will re-familiarize myself with RSpec, that wonderful spectroscopy software. Unfortunately, the seeing was still bad enough following my failed lunar voyages to suggest I would be wasting my time. Couldn't even do any visual observing, since clouds and rain were now moving back in. Astronomical road-trips? I would be heading down to the Chiefland Astronomy Village next dark of the Moon, but that was still weeks away.

I thunk and I thunk and I thunk, but I was stumped. Till one afternoon I was hunting something or other out in the Shop. I opened a cabinet, pulled out a box, looked in, and what should I see but my first real planetary camera, the good, old SAC 7B. Which brought to mind my adventures with that humble CCD—which I have talked about here before—but even moreso, it reminded me of all the fun I had during the great Mars opposition of 2003, something I haven’t talked with y’all about at length.

By 2003, Unk had been observing Mars in decidedly on-again, off-again fashion for over three decades. I’d been at least trying to see the planet since 1965. Mars, maybe even more than Saturn, was the world young Rod, like other space-crazy kids in the 1960s, wanted to see with his own eyes. Even when I was the greenest of greenhorns, I knew that most of the time Mars was nothing more than a subdued orangish star-like object. However, I also knew there were times, “oppositions,” when the planet was close to us, when Mars showed his mysterious face to Earthlings and their puny telescopes.

Even though Mars was at opposition the spring I got my first telescope, a 3-inch Tasco Newtonian, I don’t believe I saw him then. I knew Mars was visible and putting on some kind of a show since, in them days, our newspaper, The Mobile Press, carried occasional little filler-blurbs related to “space,” and I’d read one that mentioned Mars was once again close to Earth. But I had no idea how to find him. My first issue of Sky & Telescope had yet to arrive, and my only resource was my copy of the Little Golden Guide, Stars, which, while it had some planetary tables and gave the constellation Mars was sailing through that April, Leo, it didn't pin down the planet’s exact position.

I did look around for Mars in Leo's area occasionally, but none of the stars looked as obviously different to my naked eye as I thought Mars should. Certainly nothing I got in my low power eyepiece looked like anything but a pinpoint (it’s likely I actually did see Mars but mistook him for a bright star). In retrospect, I didn’t miss much. Mars was small, 14”, that opposition, and would have been a tiny, featureless b-b in my somewhat putrid little scope.

The next opposition of Mars was in April of 1967, and he was better, but only a little better, 15.5”. This was the first one I was there for. Not only did I have a mucho bettero telescope, my 4.25-inch Palomar Junior reflector, which, if not exactly a planetary powerhouse due to its small aperture, did deliver sharp images with its f/10 (actually closer to f/11) spherical primary mirror. Also, I had learned to find stuff in the sky. The epiphany arriving in December of 1965, when, just after taking my first look at M42, I captured M78 by star-hopping to it—not that I knew what I was doing was called “star-hopping” (which term may not even have been in use at then). And I had Sky & Telescope to guide me.

I’d educated myself about Mars as well as I could. Not just with the trashy sci-fi movies like The Angry Red Planet I saw down at the Roxy Theatre, but with Patrick Moore’s books. I tried to take Patrick’s cautionary words in The Amateur Astronomer to heart and not expect too much:  “When you first look at Mars through a telescope, you…may…feel a sensation of anticlimax. Instead of a globe streaked with canals and blue green vegetation, you may…make out nothing but a tiny red disk.”

I comprehended that Mars was small and far, far away even when closest to Earth, but, still, this was MARS. There must be more to it than just Patrick’s small, red disk. To be honest, what stuck in my mind from the above quote was not “small, red, disk” but “canals and blue green vegetation,” the very things my astronomy mentor was warning me not to expect.

So, one warm spring night I finally tracked down the mysterious fourth planet. Amazingly, it wasn’t even hard. Even if I hadn’t done a pretty good job or learning the constellations since that wonderful morning when the Old Man had walked into my room bearing the Tasco—I even knew subdued Virgo where the planet was now hanging out —more experienced me couldn’t have missed it. Even though this was an average opposition at best, there was Mars just burning up the sky, looking like a baleful red eye gazing down at the Rodster.

If only the view in the Pal Junior had lived up the promise of the planet’s naked eye appearance. It didn’t, of course. Not surprisingly, Patrick Moore was right on the freaking money. There were neither razor thin canals nor mysterious forests in view. It was just that damned tiny red ball. As I stared into my ½-inch Ramsden eyepiece, which delivered a magnification of 96x, I thought I caught the barest hint of a polar ice cap. But I wasn’t sure.

My big mistake? I didn’t take Patrick’s other words seriously. In addition to warning that I wouldn’t see imaginary canals and forests, he went on reassuringly to say that, with experience, I would be able to make out not just that polar cap, but also fascinating dark areas and more. I wasn’t convinced. I looked at Mars briefly a couple more times that opposition and that was it. Frankly, young Unk was not big on patience and perseverance. It would take another decade and some hard knocks before I learned better. I filed Mars away as a bust, and went back to trying to see Messier objects.

Was I disappointed? Sort of, but not really surprised. Beyond Patrick’s cautions, the photograph of Mars in my dog-eared copy of The New Handbook of the Heavens suggested I might not see much of anything. Though taken with the giant Yerkes refractor, the picture (excellent for the day) was disturbingly blurry.

Yerkes Mars...

And so it went. I put the planet out of mind, filing it away with Angry Red Planet and the other stuff of childhood. Oh, I did take a couple of stabs at it during the good oppositions of 1986 and 1988, but in the former case I was distracted by Comet Halley mania, and in the latter, by a marriage well on its way to disintegrating. When I did look with my C8, I didn't do more than take quick peeps. No filters, no waiting for nights of especially good seeing, just “Well, there it is” and moving on after a minute or so.

Nothing much changed till 1995. My life was finally settled and happy with Miss Dorothy at my side, and I had the biggest telescope I’d ever owned, Old Betsy, a 12.5-inch Dobsonian. Betsy, in addition to pulling a lot of surprisingly faint stuff out of our bright Garden District sky, was, biggest surprise of all, something of a planetary powerhouse with an excellent primary mirror despite its humble Meade pedigree.

The most important thing in helping me begin to see Mars, though, was the patience and perseverance I’d been able to develop (finally). When I first got Betsy, I began spending hours with Jupiter, trying many different magnifications and using different colored filters. I saw more of the King of the Solar System than I ever had in my life. Might the same things work with Mars?

The 1995 opposition wasn’t much of one. At a maximum size of 13.8 arc seconds, the angry one was about a quarter the size of Jupiter’s average diameter. That didn’t stop me. Seeing detail wasn’t easy. I had to wait for Mars to get as high as he could, and I had to wait for particularly stable February nights (a problem even on the Gulf Coast) so I could use high power, but from the get-go I was scoring coups. First night out, there was Syrtis Major, clear as a bell. Oh, and the polar cap was putting Unk’s eye out; how had I ever found it difficult?

I continued night after night, sometimes seeing new features, sometimes being thwarted by clouds or seeing. But I almost always saw something. The one thing I never did do, though? Photograph the planet. Given that my (film) images of much easier Jupiter resembled custard pies—at best—I figured I’d be wasting my time. Two things changed my mind about that over the following eight years: the promise of the 2003 opposition, when Mars would be bigger than he’d been for centuries or would be again for centuries, and the coming of electronic photography.

As ought-three approached, I assumed I’d be doing my Mars picture taking with my first CCD camera, a Starlight Xpress MX516. It had done a pretty good job on Jupiter. Hell, it had bettered my film images by a long shot, and was a considerable improvement over my camcorder experiments (the camcorder results were pitiful).

The MX516 probably would have done a respectable job on Mars, but as 2003 got underway, I decided I wasn’t happy with the camera. There were several reasons for that, but the foremost one was that it wasn't color. To me, the planets cry out for color. I decided I’d sell the camera on Astromart and search for the elusive more better gooder, which I at first thought was Starlight Xpress color CCD cam, the MX7C.

Soon, however, I learned that More Better Gooder for the Solar System was not another CCD camera. No, the path to Solar System success, it seemed, lay on another path. The webcam path. By 2003, amateurs had learned that webcams, the little USB video cameras used for video conferencing (and other somewhat less savory things) on the Internet were the way to go. Take an .avi movie of a planet, use software to select the best frames out of hundreds or thousands, stack those frames into a final image with this new program, Registax, and you had planetary and lunar images easily better than the best pro Solar System photos of the decade before.

I had already begun playing around with webcams, getting a Quickcam off the dang eBay, and using it to take the best lunar closeups of my life. Better than my best photographs, better than my best camcorder videos. That humble 15-dollar Quickcam could no doubt have done surprisingly nice Mars images, but since I would be selling the MX516, I could upgrade. The Quickcam worked, but its sensor, even by webcam standards, was small and low resolution, producing images with a maximum size of 320x240. What would be like the Quickcam, but better for astronomy? Lots of Web browsing and Internet astro-forum chatting (Yahoogroups and the day’s equivalent of the Cloudy Nights Forums, sci.astro.amateur) revealed that that was spelled S-A-C.

I’ve talked a little about SAC Imaging here before, but only a little. Frankly, I don’t know that much and I am not sure how much more than what I do know there is to tell, anyhow. The gist? This is the story as it’s been told to me. I’d welcome corrections from y’all.

“SAC” does not stand for “Strategic Air Command,” Unk’s old outfit. It is “Sonfest Astronomical Cameras.” Wha? Apparently a dude down in Melbourne, Florida, Bill Snyder, had a business promoting Christian music concerts, “Son-fest Promotions.” He was also apparently very interested in astronomy, and decided to begin selling astronomical CCD cameras.

Well, sorta. In the beginning, they were CCD cameras only in the sense that back in the early years of this century most webcams had (small) CCD chips rather than CMOS sensors. The SACs were humble things, just Logitech Quickcams that were repackaged in more robust bodies and equipped with 1.25-inch nosepieces for insertion in a focuser or Barlow. Yeah, “humble” is the word, but the SAC cams hit the marketplace at the perfect time, just as amateurs were discovering how good webcams were for imaging the Solar System—how amazing they were for that task.

Snyder didn’t stand still. When he met with some success, he began offering upgraded and more interesting cameras. Initially, that was the SAC 7B, which featured a Peltier cooler and was modified to yield long exposures so it could (supposedly) image the deep sky as well as the planets.

The SAC 7B was remarkably popular, enabling SAC to do the SAC 8, a more or less genuine CCD camera capable of real deep sky work. The SAC 7B was simply too noisy to be much good there, though its long exposure mode was useful for imaging Uranus, Neptune, Pluto, and the dimmer moons of the outer worlds. The SAC 8 was followed by the SAC 10 (designed in part by CCD Labs’ Bill Behrens). CCD/imaging software guru Craig Stark also had a hand in the project. The 10, with its, for the time, very impressive 3.3 megapixel sensor, was supposed to land SAC in the big-time of CCD imaging. Then, suddenly, the SAC story ended.

What happened? As is sometimes the case, apparently too much success rather than too little killed SAC. The owner made a deal with Orion (Telescope and Binocular Center) to furnish what was essentially the SAC 8 with an Orion nametag on it. Alas, Mr. Snyder couldn’t produce enough cameras to keep up with demand from Orion. He also couldn’t produce the SAC 10 cameras in numbers large enough to satisfy orders. QA problems also began to mount. Things spun out of control and SAC crashed. As far as I know, Snyder went back to his primary business—which was neither concert promoting nor camera building, but, I’ve been told, managing a motel.

I am still sorry SAC is gone. Bill Snyder had some great ideas, hired some great people, and I believe that if he’d been able to stay in business there’d be far more choices in the low-medium price CCD arena than there are today (i.e. very few). Anyhow, SAC was great while it lasted, and Mr. Snyder was responsible for me getting the Mars images of a lifetime.

As soon as I heard about the SAC 7B, I knew it was for me. It produced 640x480 images, twice the size of my Quickcam’s, had that cooler and the long exposure mod in case I wanted to experiment with longer exposures, and was ready to go out of the box. No hot gluing a 35mm film canister on the front of the camera to serve as a nosepiece like we used to do with webcams. In retrospect, I could have probably just bought the less expensive SAC 7 (no “B”), the air-cooled (no Peltier) version of the camera, and I was tempted to do that, but I’d sold my MX516 for a decent price on Astromart, so I figured I’d get the top of the line SAC. I gave Mr. Snyder my credit card number.

I ordered in early spring, and after a couple of weeks of no camera appearing on Chaos Manor South’s front porch, I began to sweat. The planet would be getting big soon, and now I didn't even have that dadgum Starlight Xpress to use on it. I understood Bill probably built cameras as orders were received, so I tried to be patient. Finally I couldn’t stand it anymore and fired off an email. The response was rapid, assuring me I’d soon have my SAC.

When it arrived, I was fairly impressed. No, the build quality wasn't comparable to the machined beauty of the MX516, but it was alright. Robust enough (tin-can-like) metal body. Good hefty cables for USB, Peltier power, and the long exposure interface. The power supply provided for the cooler was impressive in its capacity. It was undoubtedly just a surplus PC switching power supply, but it was in a nice plastic box and had a cigarette lighter output (all these years later I still use it for various things).

The only think I didn’t like about the camera was the included software, AstroVideo. It appeared to be capable, but not very user friendly, and you know how I am about that. No problemo. My astro-BBS surfing had turned up a program many webcammers were using, K3CCD Tools. It did almost as much as AstroVideo, but in a less convoluted fashion. Today, it has been surpassed by programs like FireCapture, but it is still very usable. After playing with an evaluation copy, I handed over my bucks for K3CCD right quick. With the software in place, it looked like we was ready to go.

The opposition itself was almost anticlimactic because it went so smoothly. The weather usually cooperated, and my friend Pat and I were able to live up to our vow to take advantage of every second of Mars. It was a wild time if you were an amateur astronomer. We were all obsessed by Mars; some of us even moreso than others. I was a speaker at ALCON 2003 in Nashville, and hated to give up a few nights of the planet in July. I did, however, and had a good time. Others were not so willing to part with the Old Red for even a little while. Legendary planetary imager Don Parker flew in, gave his talk, and flew right back out to get at Mars again that night.

Every clear evening, and there were plenty of them, I’d set up one of my three driven scopes in Chaos Manor South's backyard. Often that was Celestron Ultima 8, Celeste (then still on her non-goto fork). I also used the 8-inch Konus (Synta) f/5 Newtonian I'd bought to help do some of the observing for my book, The Urban Astronomer’s Guide. When I needed horsepower, it was my new NexStar 11, Big Bertha.  Even with our often good seeing, however, the focal length of the 11 tended to be a bit much most of the time. The Konus, in contrast, was too short and was mainly useful when the seeing was punk. The C8? As C8s always are, it was JUST RIGHT.

I did a little “just looking” with eyepieces on some nights, but mostly I let Pat take care of that end of the opposition. My game was pictures of Mars. Initially, I wasn’t sure how good they’d be, but I found out in a right quick hurry. On the very first evening with the camera in a 2x Barlow plugged into the visual back of the C8, Mars was surprisingly large, even in the spring (opposition didn’t come till August). And, hell, I could see signs of detail in the image on my monitor. Not just the polar cap, but those always elusive dark markings, the supposed BLUE-GREEN VEGETATION of my boyhood.

My mind wasn't truly blown, however, till I ran the night’s .avi movie files through Registax. I was somewhat familiar with the program already from experimenting with it with some of my camcorder images, but I didn't expect anything like what I got. What I got when I finished fooling with the program’s “wavelet sliders” (sharpening filters) was the best planetary images of my life. And not just that. The detail was indeed in excess of what Pic du Midi and other professional outfits had done a decade before. See the video below to get an idea of the difference Registax made.

So it went, night after night after night. As the planet rotated, more and more mysterious features came into view and went on the hard drive (of the desktop computer I dragged into the backyard). Syrtis Major, Solis Lacus, Mons Olympus. I toured all those fabled sites, and almost felt as if I were on the surface with the crew of Angry Red Planet’s Rocketship MR-1.

Then August was past and Mars was dwindling back to its normal pink b-b aspect. Was I sorry to see it go? Dang right. However, I must admit the opposition almost exhausted me—Pat said the same thing. Night after night with one target, it was the most sustained planetary campaign of my amateur career, with even my most enthusiastic lunar tears being a distant second.

Will I return to Mars? I haven't, not with a camera, though I have visited the other planets with my webcams, which have slowly evolved into more sophisticated planetary cameras like the ZWO ASI120MC I use now. However, Mars is growing again from is puny 14” diameter of recent oppositions to an impressive 24” in 2018, just a smidge smaller than in 2003. You can bet I’ll have boots on that red, red ground when that happens, muchachos.

Next Time: The Return of the King...

This was originally supposed to have been a “My Favorite Fuzzies” installment, muchachos; specifically one about everybody’s favorite nebula, M42. But I’ve decided to hold off on that. One of the goals I’ve set for myself astronomy-wise is to finally get an outstanding image of the Great Orion Nebula. Oh, I’ve gotten some OK ones over the years, but not one I consider “perfect,” even by my modest standards. So what then? How about more on Unk’s efforts to shoot the sky with Canon DSLRs?

Before we get to that, though, let me tell you my asteroid story. Last Monday afternoon found Unk scurrying around to set up Big Bertha, his C11, on her new CGEM mount.  Our quarry for the evening was to be 2004 BL86, an asteroid that was to fly by the earth at a (sorta) close distance. It was supposed to be close to magnitude 9, and would sail through a pretty region of the heavens, the area of Cancer’s M44, the Beehive Cluster.

I was all het up to see the flying mountain, and didn't think there was any way me and Bertha could miss. I had the IDs of several stars the asteroid would pass close to over the course of a couple of hours on Monday night. I’d send Bertha to one of these (SAO) stars, we’d wait, and when the asteroid passed it would be “GOT HIM!”

Monday is my teaching day at the university. I’d be home by 8 o’clock, though, and Cancer wouldn’t be high enough to fool with till 9. Still, I wouldn’t want to be lugging Bertha out into the yard and setting her up after dark. I got the CGEM assembled and the C11's OTA on it before I left for the University of South Alabama at 3 p.m. Monday afternoon.

Arriving back home after spending hours stuffing young minds with astronomical knowledge, I had to admit I was a tired. But with no setup required, I wasn’t too worried about that. Got the mount goto aligned, and testing showed Big B. was putting anything I wanted from one side of the sky to the other in the center of a 27mm Panoptic eyepiece. That silly little asteroid? I figgered “no sweat.” Uh-huh...

You know what they say about those doggone best-laid plans, doncha? With the list of my SAO stars in hand, I punched the first one into the hand control. Sucka wouldn’t take it. Tried again. Same-same. Tried the 9:30 p.m. star. Nope. The 10 o’clock one. No way. At first I wondered if my HC was inflicted with an old Celestron bug that made entering SAO stars fail. Nope, a check of the version showed that the firmware load that came with the HC was later than the afflicted build. What the hell…was something broke? Then a light went on.

The Celestron HC has a catalog of SAO stars. But not all 258,000 SAO stars. It only goes down to about magnitude 7. Hmmm…  I ran inside, fired up SkyTools 3, checked the magnitudes of my waypoint stars in the program’s Interactive Atlas, and determined that—shoot—all were dimmer than 8 and would not be in the database of the NexStar hand controller.

That was just OK. I was weary, but I reckoned I could scare up a serial cable, hook the Toshiba laptop to the mount, and send Bertha to my stars with SkyTools. As I was thinking about that, I happened to glance up and to the east and realized my target area was in the boughs of a pine tree and would be for some time to come. I shut B. down, headed inside, and had a couple of drinks.

I was in a snit, but not a huge snit. Such are the reefs and shoals of amateur astronomy, as your Uncle well knows. In other words, “You can’t win ‘em all,” “There Ain’t No Justice,” and the kind attentions of Mssrs. Murphy and Finagle are always part of our game. Luckily, my modest successes are frequent enough that I manage to carry on in spite of all my foul-ups.

“Carrying on” meant your Uncle was still bound and determined to get a convincing image of Comet Lovejoy's beautiful but elusive tail. I’d captured it (barely) with the Canon 60D and the Patriot refractor from the backyard, but you really had to hold your mouth just right to see much of it. With the comet past its peak and fleeing the inner Solar System, I knew I had to get a move on if I were to succeed.

I sure didn’t want to be caught out like I was in the days of Hale-Bopp. Back then, I was just barely getting back into astrophotography after a long hiatus. Before the Boppster left, I was able to assemble some pretty good (film) imaging gear, but by the time I figured out how to use everything again, the comet was on its way out. I never got the shot I longed for of Bopp's beautiful blue ion tail.

Saturday seemed to be D-Day for Lovejoy. There'd be a Moon in the sky, a 4.5 day old crescent, but it would be toward the west. With the comet near zenith in Aries, I hoped there wouldn't be too much interference. What would come after Saturday was more Moon and probably more clouds. I rang up my astrophotography buddy, Max, and it turned out he had the same thing in mind that I did, one last comet campaign from the Possum Swamp Astronomical Society Dark site.

I was tormented all the way out to the private airstrip we use for our observing by the suspicion that I’d forgotten something. One time I nearly pulled over to see if I had left the laptop at home, though I really knew I hadn't. I was at sixes and sevens, it seemed. What was going on? Your normally optimistic and ebullient Uncle had been in a subdued mood for days and days. Why? In part, that was simply what winter does to me. I am a spring – summer kinda guy, and my head probably won't be back on straight till the flowers are blooming and bees are buzzing again.

When I arrived at our dark site, I was all by myself at first. That didn't bother me. While my imaginary (perhaps) friends—Mothman, the Skunk Ape, and the Little Grey Dudes from Zeta Reticuli II—often keep me company on the observing field when I am alone, I knew they wouldn’t bother me tonight. Even if Max didn't show. I didn't have that creepy feeling that presages their visits. Instead, I had the blahs, which are a click up from the blues, if not quite to the level of Holly Golightly’s Mean Reds. When I am like that, the fantastical baddies have no power over me.

As I began unloading, it was clear I needn't have been paranoid about leaving some important piece of gear at home. I’d been reasonably careful with the packing, but the mainly there just wasn’t that much stuff. At least as compared to, say, a Mallincam run with the C11. There was the evening's telescope in her case, once again the little 66mm WO. She'd have enough field to take in plenty of tail, should I be able to capture much tail. There was also the VX mount and tripod. The Toshiba laptop. The Gadget bag with my Canon DSLR bodies in it. Couple of accessory boxes. Three jump start batteries. And that was it. That may sound like a heap of gear to you Dobbie fans, but for Uncle Rod that is “traveling light.”

Alright. How was the sky looking? Good, very good. Entirely cloudless. There was occasionally a light breeze, and the air felt dry. Yeah, the crescent Moon was burning surprisingly bright in the gloaming, but I knew it would be like that going in. I’d rather have the Moon than the cotton-picking clouds that have deviled me all fall and most of the winter thus far.

When the scope was assembled, next step was checking balance. I would be going unguided, and even at the short focal ratio of the 66mm scope, just a smidge less than 400mm, good balance would be important. I attached the Canon 60D to an SCT prime focus adapter (as noted in last week’s blog, the 66mm SD scopes of yore all had SCT rear ports) and adjusted the counterweight on the declination shaft till the mount was east heavy by a small amount. That ensures the gears are always engaged and improves tracking on almost any mount.

Balancing done, I removed the camera and re-installed the 2-inch SCT style diagonal. Yeah, I could do the goto and polar alignment with the camera, but I find it quicker just to use my old Meade 12mm MA crosshair eyepiece. Did a 2+4 goto alignment, and dialed in polar alignment using Cetus’ Diphda as my AllStar Polar Alignment star. Since I'd moved the mount a fair distance in altitude and azimuth to polar align, I redid the 2+4 to ensure bang-on pointing. Given the wide field of the scope, I could probably have gotten away with not redoing the goto alignment, but I could, so I did. The closer the mount put objects to dead center in the field, the quicker I would be able to work.

Hokay. Started Nebulosity 3, plugged the camera’s USB cable into the PC, and focused up. I was still sitting on my last calibration star, Aldebaran, so I used that to achieve rough focus. When it was nice and small, the dim field stars began to be visible in the successive 1-second exposures in Neb’s Frame and Focus mode. When they were as small as I could get them by eye, I switched to Fine Focus, clicked on a small field star, and made its Half Flux Radius number as small as I could get it.

Onto Lovejoy. Just as I had for my previous expeditions to the visitor, I’d printed out an ephemeris with my favo-right planetarium program, Starry Night Pro Plus 6. I entered the set of coordinates closest to the current time into the NexStar HC using the “goto R.A./Dec” utility, pressed “Enter,” and away went the VX mount. When it stopped, I fired off a 5-second exposure using Neb’s Preview function. There the hairy star was, well framed and not looking any dimmer than she had a week previously.

Before I spent an hour or more on the comet, however, I wanted to know whether the tail was doable or not. I set the ISO of the Canon to 3200, which might be pushing it a little in the Moonlight, but which might help with the subtle tail. Set the exposure time to 2-minutes, and mashed “Preview.” What did I see when the finished picture appeared on the laptop screen? The stars were nice, round pinpoints. It sure is nice the VX - Patriot combo doesn't require guiding for 2-minute exposures. The tail? Easily visible, but not exactly putting my eye out.  It was good enough, though, that I thought I might really get something if I stacked 30 2-minute subs.

I set up the exposure series, hit the “go” button, and Nebulosity and the Canon began doing their thing. What now? I wandered the field, spending some time watching Max, who’d arrived as I was setting up the telescope, work with his VX, his wide-field 5-inch Newtonian, and his Sony Camera. He was getting some nice frames already. Another PSAS buddy, Gene, had showed up at sunset, and I enjoyed observing this and that with him using his nice visual rig, a 6-inch f/8 Celestron refractor on an Atlas mount. I’ll tell y’all, if the six-inchers weren't so blamed heavy, I’d have one.

Mostly, though, I scanned the skies with Miss Dorothy’s prized Canon roof binoculars. They are “just” 32mm glasses, but they are finely made, and with a magnification of 8x they don't give up much—if anything—to a pair of el cheapo 10x50s. I looked at all the obvious binocular stuff, including M42, which is now getting nice and high in the east early in the evening, and Gemini’s M35. Mostly, though I looked at Lovejoy.

It was bright in the glasses. No tail, but a prominent nucleus and plenty of coma.  My main goal was to pin down the comet’s position exactly and see if I could detect it naked eye. I’d thought I’d maybe glimpsed the fuzzball from the backyard on one good night not long before Lovejoy’s peak, but was not totally sure. On this night? I was pretty sure. There seemed to be a dim fuzzy in approximately the correct location, but it was not an easy observation even with the comet riding high and in skies considerably darker than those of the New Manse’s back-forty.

There was still quite a while to go on the exposures, so I did a little more binocular gazing and had a peep at M82 in Gene’s refractor—just doesn't seem possible Ursa Major is back already. As Max waited for his sequence to complete and I waited on mine, we got to talking comets. Sure would be cool to get a great one soon. The last comet we had that even comes close to that appellation was weird Comet Holmes (which is undergoing a minor outburst right now), and hard as it is to believe, that was seven freaking years ago. We are almost in a comet drought like the one between Halley and Hyakutake.

Just as I was getting warmed up on the subject of My Favorite Comet of All Time (West), the Toshiba Laptop played the little fanfare that is Nebulosity’s way of saying “Sequence is done, Uncle Rod.” Hmm. What now? I could do more comet frames, but I believed I had enough for a reasonable image. I wanted to do one more target, though, and the natural seemed to be M31, which was not too high and not too low.

As I mentioned here, I’ve been after a good picture of the famous Andromeda Nebula (Galaxy) for a long time, and I thought the little Patriot would have the field to do a nice job on the huge object. Did a preview shot of the galaxy, and the framing was good without me having to touch a thing other than change the camera angle (the Patriot has a rotatable focuser) so the galaxy was a little more horizontal. The Moon, not too far away, was obviously making the background brighter than it would normally have been, but watcha gonna do?

Set up for thirty subs of the beast. That would take a while, and it was now a bit on the chilly side, but I figgered if I were gonna do it, I’d do it right. Once the sequence was underway, I walked over to the fire-pit near the hangar where the remains of a fire built by one of the airfield’s owners still burned. I sat in a lawn chair and warmed myself while waiting for M31 to finish.

Actually, it was not terribly cold. It should have been chillier, but the humidity had spiked up at mid-evening and so had the temperature. I knew what that meant:  clouds coming. And more than a few were now visible on the western horizon. There was no doubt, however, that I’d get M31 in the can before they arrived.

When the galaxy finished, me and my two companions were not quite ready to call it a night, though we thought the end was in sight. Just for the heck of it, I slewed over to the Horsehead Nebula and did five 30-second frames. After that, I packed up and pointed the 4Runner for the New Manse, quitting the site well before midnight.

As is my usual wont, I studiously avoided looking at any of the images when I got home. They always look horrible at the end of a long night, and I knew they would appear far better in the morning. Instead, I surfed the cable TV channels for a little while, warmed myself with the aid of the sainted Rebel Yell bottle, and, finally toddled off to bed as midnight came and went.

Next morning I copied all the subs from the laptop to the desktop in my office over our home network and went to work, starting with the comet. Only problem I had was that in these fairly long subs, the nucleus was not a “star.” It was a sizable ball, and it was a little hard to position the cursor in Nebulosity dead center enough on it to ensure good stacking. In the end, I did two separate stacks.

The verdict? I’ve seen far better images of the comet’s tail on Facebook, but given the Moon’s presence, I’m pleased. The coma is, as in my backyard pix, a pretty green. More importantly, the comet’s tail and spiky secondary tail(s) are just as distinct as I’d hoped they would be. Perfect? No, but I most assuredly did not let this one get away.

M31 was another winner by my humble standards. Oh, it would have been better without Luna nearby, but not bad. I hope to do better still, but I would not be surprised if that has to wait till next year. In a month’s time, assuming the clouds leave me alone, it’s possible I might tackle it again, but it will be beginning to get low by the end of any decent exposure sequence, and I am skeptical the weather gods will cooperate. We’ll see.

Perhaps the biggest surprise of the evening? The Horsehead Nebula. With only 150-seconds of data (though I did crank up the ISO to 6400), there was no way this was going to be a pretty picture. However, I did get a picture and not an entirely horrible one considering. The Horse is there, and there is even a little detail in the red background nebula, dim IC434.

Which makes a point I’ve been talking up for some time. Novice imagers who spend their time reading in the Internet astronomy chat-rooms have the idea that you must have your DSLR modded (have its built in IR filter removed) to do any deep sky imaging. Clearly not true. Modding a camera helps, muchachos, especially with dim red nebulae, but you can still get ‘em with your stock DSLR. It’s a little harder and takes a little longer but you can do it. If your fumbling and bumbling Uncle can image the freaking Horsehead with his unmodified Canon 60D with less than 5-minutes of exposure, the sky is, quite literally, the limit.

Next Time: Big Time…
