We dodged clouds, principally in the south, all night. We caught the gibbous Venus & beautiful Crescent Moon early, but quickly turned our attention to Jupiter. Io created a transit near the Jovian lower right limb, the moon itself hidden in the Jovian clouds in the foreground. Europa was off to the left (in Mark & my Newtonians, to the right in Richard’s Mak)
Ganymede much further out off to the right, while Callisto was farther still, far away to the right

Saturn, big band across his center, with the Cassini Division very clear, while the shadow the globe cast against the back portion of the rings demonstrated the 3-D effect of visual viewing so hard to replicate in photography.

We saw …
Albireo (β Cygni) — beautiful, colorful double
Izar (ε Boötis) — also beautiful, but tight, double (white-yellow primary, blue secondary)
A fruitless search for NGC 6826, Blinking Planetary Nebula
Coathangar asterism (Brocchi’s Cluster, Cr 399), nice is the finder scope, too big for my dob
M51/NGC 5195 (somewhat disappointing this night)
M81/82 (no NGC 3077)
Hershel’s Garnet Star, μ Cep (mostly orange-ish to us)
M22 in Sagittarius (great gobular!)
M17 Swan Nebula in Sagittarius
M16 Eagle Nebula (Open Cluster), in Serpens
M8 Lagoon Nebula in Sagittarius
M20 Trifid Nebula inSagittarius
M57 (as Steve was leaving) in Lyra
Cor Coroli, α CVn — pretty double
M3 in Canes Venatici

We returned to Jupiter, noting Io’s transit progression across the Jovian surface, right-to-left, with the emerging of the moon proper from Jove’s left side (Newtonian perspective, of course).

Saving the worst for last, though typical of the clouds we dodged, a light sprinkling fell as I put up my dobsonian at about 1:30 in the morning. A nice evening under the stars.

I arrived quite late for this public star party, probably around 10:15 or so, and wasn’t setup to observe until no earlier than 10:30. Scott and Gary were probably put off by all the clouds and wind, earlier, and we did indeed have plenty of wind at first (and later as we finished), as well as some patches of clouds, but compared to what we’d feared from earlier in the day, I’d say we got relatively lucky. It wasn’t a great night for astronomy by any means, but it wasn’t the miserable result we had feared, with the winds considerably less than forecast. Steve Maas showed up about 10 minutes or so after me.

Arriving as late as I did, Venus was already behind a west tree, so that option was out, as were all the Geminid targets. I put Algieba, Gamma Leonis, into the eyepiece and upped the power with my 9mm Nagler T6 to 133.33X, which would be my workhorse eyepiece. Although I’d have liked to go to higher power, the wind was still pretty bad, not as bad as forecast and feared, but hardly calm, and the skies were turbulent, limiting high power options. Still, the 9mm yielded a clean split, and I showed this off to everyone, as well as pointing out Algieba’s location so Richard and Mark could put it in their scopes.

I put in M57 in the eyepiece with the Nagler 13mm T6 for a nice balance of wider field for placement, yet enough power to see some detail in the nebula.

We couldn’t resist looking at Jupiter, and again, the King of the Gods was ready to oblige with the visual bonanza only Dies Pater can orchestrate. A shadow transit was in progress (Io, yet hidden in the foreground amongst the upper atmospheric clouds), with the Great Red Spot adding to the spectacle. What a hoot! Callisto was way off to the left, with Europa moderately close to the globe to the right, followed by Ganymede farther. Everyone stared long and hard at Jupiter, taking our time. What a beauty! The 10″ put up a nice, bright image. We came back to it later and saw Io pulling off the lower left side of the globe. I mostly used my 9mm T6 for 133X, since the atmospherics were unfriendly to higher power. Later, we split the low-hanging fruit of Zubenelgenubi, just down from Jupiter.

I put my telescope on Cor Caroli, and was immediately impressed with the beautiful yellow-white primary and blue-white secondary and the colors my 6″ scope demonstrated. One of the better doubles of the night, and quite colorful and rich in the 6″ dob. This was an easy split in the Pan 24. This was followed up by the best double star in the night sky, Albireo. The orange and blue stars that comprise this gem of the night sky set the standard for colorful double stars, and did not disappoint tonight.

Ray Smead requested Mizar, and we easily showed the triple Mizar A, Mizar B, & Alcor. I split Beta Scorpii, Graffias, quickly followed by Nu Scorpii, which required some pretty high power to split the B-component.

We had a couple of people wander by and take looks through the scopes around Tech Terrace Park, but mostly it was the SPAC members listed above. Had a nice night under the moon and stars and looking forward to our next outing at Tech Terrace Park on July the 20th, weather permitting

My hoped for big turnout for the end-of-school fizzled without a student, and we put on a public star party for ourselves, but that was okay. I learned a few things in the process of observing and enjoyed the camaraderie in the ancient practice of stargazing, joining us to the Hershels, Galileo, the Romans, Greeks, Mayans, Han Dynasty, Jyotisha, Egyptians and Sumerians, doubtless before.

I arrived as Richard Craig was setting up, and Steve asked how I could actually get there on time, so often late. But I started setting up about 9:15, skyglow in the west from the sun just below the horizon. Venus was already bright in the west, so I used her to setup my Rigel and 30mm RA finderscope. She was a nice sight in the Pan 24, a gibbous, featureless moon on the opposite side of the sky.

With everything lined up, and now Pollux and Castor coming through the deepening dusk, I tried M35 in the scope, very near Venus. Found it, but, boy, was it disappointing! Gosh, the contrast was all gone as the stars tried to break through the creamy background. Turned me off completely from wanting to look at open clusters for the rest of the evening. For sure, my hoped for quartet of M35, 37, 36 & 38 dissolved like the twilight, a set one cannot observe with any satisfaction in late May. Oh well, live and learn.

Being in the neighborhood, I split Castor for grins. It was pretty tight and required the 11mm Nagler at 112x for a clean, if somewhat tight split.

So with twilight still in the sky, I decided a good look at the moon would be okay, blinding, but at this time of the evening, okay. And we were not disappointed about the blinding part. Luna was bright and searing, making whichever eye one used to observe her utterly useless once you’d backed off from the scope, overwhelmed by the photon flood she just poured into your cornea. But for that flood, a wonderful sight of the huge ray craters Tycho and Copernicus dominated her rugged terrain south and north of the lunar equator. Still some shadows on Kepler, and the terminator was awash in detail. And awash is the right term, since the thermal stability of the evening at that point was quite heat bedeviled. Having reached 99 degrees Fahrenheit officially, the sky was wavering under magnification, and the moon demonstrated this better than anything else in the sky.

Tom Heisey had setup his TV 101 F/5.4 on a Losmandy EQ mount by that time. It was interesting how much better it seemed to take the heat. The images rippled in it, too, but they somehow seemed more stable. Perhaps the extra-wavery images came from tube currents in my tube? I didn’t use a fan on my Z8, so was subject to the whims of the environment, but the scope had been stored indoors, and the temperature, though a little hotter, wasn’t a whole lot warmer at the Park than in my home (80* to about 90*).

And this thermal stability of the refractor over the images in my Z8 was even more demonstrated on Jupiter. Although by the time we got to Jupiter, Gary has his 12” dob set up. But I jump ahead of myself.

There were a bunch of double stars to crack, and after Castor and the moon, I began cracking them. Kappa Geminorum I just flat missed by not checking my observation list. Duh! But I nabbed Algieba, Gamma Leonis, easily enough. Again, I needed 112x to split it, but didn’t really like the view at higher powers, so a tight split would have to do for this yellow-white pair.

Cor Coroli was next, and almost straight overhead, so in the difficult “dob hole” region of the sky that made getting it into the eyepiece more challenging, but I managed to steer the scope onto the target with sufficient effort, and this nice white-blue primary and white-green secondary was pleasing to the eye.

Iota Cancri proved to be the most appealing double of the night, with its yellow primary and blue-ish secondary a striking pair, and the most attractive double our moon drenched sky would afford.

Because Mark, then Lesley and Scott all showed up later, I made two tours of the better naked eye doubles, and so made two passes at Castor, Iota Cancri, Algieba and Cor Coroli. Like Ella Fitzgerald sang, “Nice work if you can get it, and you can get it if you try.”

We tried to get M3, but it was simply too close to the bright gibbous moon, and all efforts produced washed out skies with no globular in sight!

I went after Izar, Epsilon Boötes, and discovered more heat issues. With its white primary and blue-ish secondary, it could be split at 176x with the 7mm Nagler, but the scintillation of the primary under the high power and thermal issues, made the split temporal at best, with the primary morphing in the eyepiece to merge into the secondary most of the time, with only momentary glimpses of the secondary, when the image would momentarily settle down. That was disappointing, but a characteristic and bedeviled the splitting of Porrima, Gamma Virginis,too, and in exactly the same way.

Our one good DSO for the evening turned out to be M13, the Great Hercules Cluster, and “Great” it was. Nothing like under a dark sky in the country, mind you, but at least it was interesting to look at, with actual characteristics observable, especially in Gary’s 12” dob. This scope produced, by far, the best image of M13 of the scopes on the field. My Z8 did a reasonable job under the circumstances, but the 12” dob with Gary’s 13mm Ethos (and 17mm Ethos) produced the best image of M13.

But the most intriguing body in the sky this evening was, of course, Optimus Maximus himself, Jupiter Rex. Beautiful and resplendent with creamy stripes and brown bands, I don’t think the Great Red Spot was out, but all four Galilean satellites sprawled flanked the great King. And on Jupiter I made some interesting observations from the various scopes. First, having a tracking mounted, well made refractor, is hard to beat on planets. And the only scope that could was Gary’s 12” dob. By sheer force of photons, yes, Gary’s view was the best, but not by a lot, and honestly, Tom’s TV 101 put up a more effective view, using my TeleVue DeLite 3 & 4mm eyepieces, of Jupiter, than even my Z8. This is not to say my view was inferior, exactly, only that the thermal issues that bedeviled my double star efforts continued here, and even though the refractor’s image also rippled with atmospheric heat waves, the scope itself wasn’t adding to the problem, and this did not seem to be the case with the dobsonians. But at 12”, the sheer number of photons a 12” mirror could bring to bear on an on-axis target like Jupiter overwhelmed the other considerations, but it took that much! The little 4” refractor really could keep up, and not having to manually track was big advantage, especially under the heat soaked circumstances.

I finished by splitting Algorab, Delta Corvi. I like the Star Splitters descriptions of Delta Corvi, a fairly wide pair with enough color difference to give the effect of a star and planet combination. Indeed, I see a yellow-white primary and a brownish white secondary, planetary indeed.

It was late and I was very tired. I packed up, shook some hands and drove towards the home, fortunately not very far away.

Observation Report, Camp Rio Blanco, 14-April-2018

The last astronomer from Lubbock to arrive, I pulled into Camp Rio Blanco at about 10:20, and aligned my Rigel & 50mm Right-Angle finders to Castor by 10:45. I installed the Explore Scientific 28mm 68* eyepiece to start things off, offering some of the widest fields of view I can get out of my scope, and proceeded to examine M42, swimming in a sea of disordered turbulence near the horizon this mid-April evening. The Trapezium showed up, as well as the rose-shaped nebulosity, but the wavering, watery low-power view guaranteed that higher power would not be rewarded this evening, at least not anywhere near the horizon, but I would find the “seeing” this night not conducive to high power, even towards the zenith. Scott forewarned me of this, and he was right.

But I have to test everything for myself, so I put in a 5mm T6 Nagler, for a whopping 246x view, only to find Castor turned to mush, so, indeed, no high powered viewing this evening; the skies didn’t support it. Fortunately, my 11mm T6 (112x) was enough to split the pair, and Alpha Geminorum resolved into a pair of tight, white pinpoints.

So I returned to wider powered views, putting M37 into the eyepiece. I loaned Richard my ES 28mm 68* eyepiece for him to find M35 as well, and I, having used that same eyepiece to find M35 with ghostly NGC 2158 beside it, dropped a SuperView 42mm into the focuser to continue my wide angle, 2″ eyepiece viewing experience in my dobsonian. Although M37, probably my all time favorite open cluster, or at least a serious contender to M11, looked very, very nice in my SV 42mm, I prefer the vista in the ES 28mm 68*. Somewhat higher magnification with not a whole lot loss of field, it’s hard to beat in my dobsonian.

But Richard was about finished and he soon packed up and left, so I put the ES 28mm 68* back in the focuser and continued on my star path to M36, then M38 with its ghostly NGC 1907 companion. It’s odd to me how many star guidebooks miss this simple collection of open clusters. M35 (with NGC 2158), M37, M36 & M38 (with NGC 1907) form a nice grouping of Messier open clusters, with the orderly first and last having faint, much more distant NGC open clusters behind them providing ghostly companions to these “bookends”, with the two out-of-order clusters in-between. Fellow astronomer and dragonfly enthusiast Jerry Hatfield has christened M38 the “Zia” cluster, after the symbol that centers the New Mexico state flag, and to which M38 has a modern-artsy-ish resemblance.

Mark Smith put M81/M82 into the eyepiece, and was that a sight! That old 10″ F/5.5 has some nice optics, and Mark was sharing the views. Besides these two, one could pan over from M81 and pick up NGC 3077 as well. A nice set. And Gary Leiker was able to fish out M100 in Coma Berenices in his 12″ SCT. It was dim, but pretty, the 12″ of aperture demonstrating its photon grabbing capabilities. Didn’t see much of Lesley, it was pretty cool when I arrived and only got colder as the night went along, so she spent most of her time in Scott’s pickup with blankets on herself. Scott, on the other hand, kept his C8 on Jupiter, which, as the night evolved, turned from a churning white dot to at least a wavy striped planet, the higher it got above the horizon (tho never high enough to be good and stable, given its present, pre-opposition position in the sky). Was good to have our only engaged couple out, tho. Even love birds should be able to fly to the heavens from time to time.

After meandering between Taurus and Auriga, I returned to Gemini to try and grab NGC 2392, the Eskimo Nebula, the vast, dying ember of a white dwarf shrouded in its thrown off shells of gas, giving it a distinct, gray-aquamarine eskimo-parka appearance. After some interaction with my copy of the Sky & Telescope Pocket Atlas, I found our hooded, glowing, post-fusion stellar friend.

From Gemini, I went to Cancer and the Beehive, M44. Andrea and her mother, Victoria, came by briefly to observe with the other Girl Scouts in bed, as Richard headed out. The Beehive was glowing in the sky overhead, with Mark borrowing my Pan 24, and me hot on the heels of the Eskimo, having put in the 1.25″ Tele Vue 11mm T6, tried to show her the Beehive through my dob with the Tele Vue 16mm T5. Although it affords just over a degree in my dob, that’s not nearly enough to frame the Beehive very well, but it is obvious that M44 is, indeed, composed of a bunch of individual stars, and Andrea was impressed, so there ya go.

Although Andrea and Victoria didn’t hang around too long to see, next up for me was the nearby colorful double star Iota Cancri. Although pretty, I enjoyed splitting Gamma Leonis, Algieba, more. It’s tighter, and although the colors are more subtle, there is a difference between them (cream and gray-green to me). Their tightness, along with the higher power required to separate them, made them more challenging and consequently satisfying to split than the wide Iota Cancri.

Gary, Scott and Mark began to pack up, but I fell deeper into outer space — 21 million light years away to the Pinwheel Galaxy, M101 in Ursa Major. For the rest of the evening I’d use the 1.55* field the 2″ Explore Scientific 28mm 68* eyepiece affords in my scope. Although always faint and ghostly, the spiral arms could just be made out in these dark, eastern Crosby County skies off the Caprock in my 8″ dob. And 23 million light year away M51, the Whirlpool Galaxy, technically in Canes Venatici, but closer to the end star of the Big Dipper, Alkaid, than Cor Coroli showed forth its round galactic arms. Of course, one gets two galaxies here, with nearby dwarf galaxy NGC 5195 interacting with its huge, spiral armed master, M51.

In the neighborhood, I went down just below to the “bottom right” of the bowl of the Dipper and observed the 46 million light years away edge-on galaxy M108, along with the mere 2,030 light year distant Owl Nebula, M97. Fellow astronomers gone, it was me, the sky, the coyote calls and the cool of the April deep-evening.

Noticing Arcturus, I jumped over to the globular cluster M3 in Canes Venatici, some 33,900 light years distant. This is a nice sight framed against the sky, but it was back to Leo and galaxies, as New Moon in Spring calls for. Turning my attention to the underbelly of the Lion, I was able to frame the squat triangle that M95, M96 (squat “top”), and M106 comprise. Also, M106 has the adjacent NGC 3384 just off to its side, and just outside the “bottom” of the triangle in my newtonian reflector. They make a great pairing, and point to a bunch more faint NGC’s up, closer to the belly of Leo. A wonderful place to graze, but I was beginning to feel the cold and still wanted to get in the famous Leo Triplet, so broke off my underbelly oogling and was off to the hind leg.

And just down the hind leg, of course, lies the Leo Triplet of galaxies, M65, M66 with NGC 3628 as the flat top of the triangle, such majestic beauties about the Lion’s thigh.

My send-off vista would be M104, the Sombrero Galaxy, just above Corvus in Virgo, 31-odd million light years distant. The dust lane was visible, and this was a wonderful sight to end a beautiful evening. I hope the Girl Scouts enjoyed it. I know I did. A special thanks to Charles Barker for inviting us and having us out.

Your humble narrator with his Kunming 102mm F/7 refractor and SkyWatcher 130 F/5 reflector on the GSO SkyView Delux alt-az mount with AstroTech Voyager Extension tube

I arrived around 9:50 PM and was setup with my Kunming 4” F/7 ED refractor by 10:15. Setting up my finders on Rigel, I was ready to observe, and pulled in h3945, Hershel’s own “Winter Albireo” in Canis Major.

Richard provided us with Spotify orchestral “Space Music”, starting off with Richard Strauss’ Also Sprach Zarathustra, Introduction, from 2001: A Space Odyssey. That was followed up by the Star Wars Main Theme, Cantina Band and The Imperial March to get us in the mood. Thanks, Richard!

Since I got there late, everyone else was enjoying — what else while you can in late March — M42, the Great Orion Nebula and the Trapezium, the “four” stars that make up faint naked eye Theta Orionis. Of course, there are WAY more than four stars in Theta Orionis. Many are beyond the reach of mobile amateur telescopes, but at least 6 are definitely not, although four are visible to just about any scope worth its salt, even quite small ones. But the “E” and “F” stars are subtle, well within the range of small amateur scopes, but require cooperation from earth’s atmosphere, in conjunction with the light gathering aperture of the telescope involved. Huh? Well, on a calm, cooperative atmospheric earth night, any reasonably good 90mm scope should capture all 6 stars of the Trapezium. Trouble is, Mater Terra’s furiously churning oceans of air rarely permit this, such that, under this Saturday night, March 17, aye, the very Saint Patrick’s Day 2018, even Gary’s 12” dobsonian had great difficulty picking up “F”. In fact, I never personally observed “F”, but Scott said he’d caught it flickering in and out.

Scott’s ability to catch “F” is not surprising. Visual astronomy is, in a very real sense, a skill like playing the guitar, or tennis. The amount of practice one gets, the hours under-the-stars, or on-the-court, so to speak, matters — a lot. Lately, with work, family, and uncooperative weather, I simply haven’t observed much. That’s not to say that Scott’s been observing constantly, but I suspect he’s gotten more observing in this past Winter than me. And Richard was unhappy that he thought his little Mak only got three stars of the Trapezium, even tho I saw it easily resolve all four, because I’d seen the Trapezium moments earlier in my own refractor.

In fact, with the ground wind as strong as it was Saturday night, beating all our scopes in such a way that all I could possibly resolve in my refactor was four wiggly stars. Gary’s considerably more stable 12” dob, on the other hand, easily resolved “E”, tho I never saw “F”, to give you an idea of the conditions we observed under. 12” of aperture to gather light, and only “E”? That’s some bad seeing. Besides this, the wind, tho certainly more resistant, still hit the big 12” dob, rattling the image some, nothing like my refractor, but still making to resolution of fine details at the eyepiece a difficult proposition.

We decided to see what we could do with multiple star Sigma Orionis. Again, Gary’s 12” dob grabbed all four main components, even faint C. My refractor only saw AB, D & E, but again, the wind made resolving fine details a jumping jumbled gamble to lose.

Giving up on high powered views from my refractor, I retired my 7mm T6 and put the 2” ES 28mm 68* eyepiece into the focuser. Gary went with one of his wider Ethos. M35, a mere 3000 light years away, with its ghostly companion open cluster NGC 2158 (16,000 lya) made a good appearance in our telescopes at low power, Gary’s able to begin to resolve the much more distant 2158 into its stellar constituents. The Double Cluster, NGC 869 & 884, made for nice fare before they set behind the roof of the Observatory. M37 in Auriga with its bright orange center star surrounded by blue-white stars.

Giving up on high power, I put up my 4” refractor and went with the SkyWatcher 130mm F/5 reflector. The Leo Triplet, M65, M66 & NGC 3628 formed the nice flat-topped triangle they are. M81 & M82 (and NGC 3077 farther afield) made nice appearances, especially M81’s spirals and M82’s fractured core in Gary’s 12” dob, as he changed out the 17mm Ethos for the 13mm. He also picked up M51’s swirls with NGC 5195. My views were wider field, but less detailed.

Our finale was M1. Not much more than a cotton ball in my smaller scopes, it came to life in Gary’s 12”. It looked good in the 17mm Ethos, better in the 11mm Ethos, but Scott’s 11mm Nagler T6 produced, as Gary called it, “the money shot.” Indeed, the mottling on the Crab Nebula, something I don’t think I’ve ever seen out at the Gott, although I’ve caught it at Emma in a 10” scope, was visible in the T6.

It was late and we packed it in, and we enjoyed our time out under the stars, and the camaraderie of fellow astronomers. We drove home tired, but a little more visual astronomy the wiser.

Observation Report, 10-Dec-2017

Gary Leiker 4.5″ Orion Starblast
Darien Perla C8 fork mount
Your humble narrator 4″ F/7 ED Chinese refractor
Mark Smith 10″ F/5.58 dob

I arrived later than I’d have liked, but it can be difficult to make my wife appreciate astronomy anything like shopping at Lowe’s, but home improvement is a good thing, too.

I brought my Orion 102mm F/7 ED refractor (Kunming Optical OEM), Gary had his StarBlast 4.5” F/4, Mark had his 10” F/5.58 dob, and Darien had his C8 fork mount setup doing astrophotography.

I began the evening aligning my visual finderscope, tried to get my 8×50 RA to work, but it’ll take some fiddling with in the daytime. This evening I finally got the 6×30 RA aligned and the Double Double was a very difficult split that night. Unfortunately, that was the way it would be. Double star splits, in particular, were extremely difficult, and Epsilon Lyrae set the evening’s trend. With the 5mm Nagler T6, they both split, but just barely, and that was 144 power! Even then, the right pair split easier than the left, and one had to wait it out for the snowman to split in half with the left pair. So much for the seeing, but the skies, after a brief time of cloudiness at setup, revealed a glorious celestial dome of stars.

I tried to split Delta Cygni, a task I’ve easily done with my C102GT and 6mm BCO (almost 170 power), but try as I might, and I exceeded this power by quite a bit when I little wouldn’t do it, I saw no double. Folks, the seeing wasn’t so hot.

In the neighborhood, and a bit put off by high powered efforts, I switched to low power, 2″ eyepiece viewing. I got a nice 25.5 power, 2-2/3 degree true field of view from the ES 28mm 68* eyepiece, and that’s what I used for a while, gobbling up Sulafat (Gamma Lyrae), the Ring Nebula (M57), and Sheliak (Beta Lyrae) with room to spare about them. It was a tiny Ring Nebula, of course, but was it in context!

At Darien’s calling, Mark put Caroline Herschel’s Rose Cluster, NGC 7789 into his 10″ dob, and am I glad he did. The Rose really does have a blooming flower appearance, small dark linings amongst the stars that seem to outline petals on a rose. NGC 7789 is worth the effort, just off and up from Caph, as tho to continue the “W” zig-zag pattern in the sky.

On to Andromeda, and to no one’s surprise, Mark’s view of M31, with the distinct dust lane, like Bob Ross had taken an eraser to the galaxy across the top, like a hat’s rim. I rather liked my less detailed, but more dramatic capturing of M31, M32 and M110 all together in my refractor, still with the wide field ES 28mm 68*. Looks awfully nice in a 2-2/3 degree field.

Albireo was a beauty, as usual, the Orange and Blue pair never failing in splendor. I scooped up M27, the Dumbbell Nebula, and brightest of the Messiers while I was in the neighborhood. And the Double Cluster, NGCs 869 & 884, added to this wide field sweep. Even the ET Cluster, NGC 457 in Cassiopeia looked pretty nice at 25.5 power. He was smaller than normal,true, but still distinct and easy to pick out in the dense starfield that is this Milky Way constellation.

I tried for M1, the Crab Nebula, still somewhat low in the east, small, but visible as a cotton ball. Gary started talking about the 100 sisters of the Pleiades he had in his StarBlast, and indeed, he did have them. Couldn’t resist putting them all in my refractor, either.

At Eta Cassiopeia I believe I returned to 1.25” eyepieces. Another beautiful, colorful pairing. With the Pan 24, I went after M35, ghostly NGC 2158 behind it. This pair of clusters forms the “ends” of a set of open clusters, with M38/NGC 1907 its other end, and M37 & M36, in that order, in between. So they begin and end in order, with the middles “swapped”. Also, the beginning and ending have distant, ghostly clusters farther behind them. In M35’s case, some four times more distant; in M38’s case, a mere 300 more light years behind this 4,200 light year away Messier Object.

Attempting to torture myself, I put M33, almost at zenith, in the eyepiece of my refractor. It was nice, and there was almost an expression of “arms” in this most interesting of galaxies. The seeing was better near zenith, or at least it was when I was looking at M33. We went after Mirach and his “ghost”, elliptical galaxy NGC 404. Got ‘em, alright. I was done with groveling on the ground when I commandeered Mark’s dob (he was off talking to Gary and Darien anyway) and put Gamma Andromedae, Almach, in the eyepiece. Again, another pretty, colorful split.

We hurried back to the west to catch M15, off the end of Pegasus’ nose star Enif. We tried Orion targets, getting a rather poor M78. I really couldn’t make out the Flame Tree Nebula (NGC 2024), which was disappointing. My split of Rigel was just plain terrible, and the Trapezium yielded bloated, unfocused stars that could not be focused, and the focuser on my 102 ED, tho only single speed Crayford, is pretty world-class. But that was the seeing. No tight Trapezium (and you could forget E & F, since A-D were as ugly a stars a person could put in the eyepiece).

So not the best night for stars at high power, but a nice night of low power viewing. It was getting late for a “school” night, we were all getting quite cold, and the clouds started to roll back in. Mother Nature even wanted us to quit, so we packed up and headed back south to the city, and our respective warm beds.

Although I’d hoped to arrive right at dusk, 7:30, having already packed my scope into the car by 7 PM, I managed to waste enough time puttering about the house to arrive at 8:15. Still a tiny bit of sky glow from the sun in the west, but definitely dark enough to be looking, even as I had to unload everything and set things up first. Oh well, by 8:30 I suppose I was aligning my Rigel illuminated reticle and Orion 9×50 right angle finders.

I used sinking Saturn to make all my finderscope adjustments, using a Nagler 16mm T5 for 77 power and just over a degree to provide a nice, wide field, but enough power for some definition. I tried the 7mm Nagler, but at that low altitude above the horizon, no go. So I backed off to the 9mm, but settled on the 11mm Nagler T6, for a 112x view. Small, yes, but as good as could be afforded so close to the heat-rippling, thick atmosphere of Mother Earth. Even lower in the west and north was the rather small crescent moon. I should have pulled out the 11 and gone back to the 16, shimmering in the low altitude heat waves as the image was.

I turned to the rapidly setting Sagittarian fare before they were spun below the horizon. Getting in the vicinity with the Rigel, I sleuthed about with the Orion 9x50RA and found the Lagoon, M8, easily. In my 9×50, I can even see M20 as well, but first things first. The Lagoon was a nice site in the 16mm Nagler. This is such a good eyepiece for framing things while still getting enough power to get a good idea of your target, and it proved this Sunday evening. Then off to the Trifid. Low as it was, and somewhat light polluted at the Gott, it was hard to determine the exact triple nature of the nebula, though a dark lane was evident in this dust and gas celestial masterpiece.

The Swan, M20, was next, and she was gracefully riding the skies as though on a placid lake, perhaps at a bit of an angle, yes, but stately, dignified and calm.

Still wanting to grab all the western targets I could, I rushed up to Hercules to pluck out that gem of the northern celestial skies, the globular M13. After finding it, I first put back in the 11mm for 112x again, then let everyone else take a peek, and what a nice peek it was. This is such a majestic object, or, as Dave in 2001: A Space Odyssey exclaimed, “My God, it’s full of stars!” Indeedy do.

And speaking of stars and Hercules, Alpha Herculis, a.k.a. Rasalgethi, is a beautiful double star. This is a nice pair, with a rather orange primary and white secondary, at least tonight in my Z8 dob.

M11, the Wild Duck Cluster, was another wonderful site, followed by the Ring Nebula, M57 and the Double Double, Epsilon Lyrae. The Nagler 16mm at 77x was just enough to split the Double Double. It was just barely split, yes, but both pairs split just the same, and both genuine splits, not snowmen. I thought that was something nice, but looking at the Cloudy Nights website, I see it’s not so unusual.

By this time, Jerry Hatfield had arrived and encouraged Charles to put one of his nicer, newer eyepieces on M57. They had complained about the image, but when I went over and focused it, gosh, what was there to complain about? Looked great.

Getting lower, Jerry scooped up the Saturn Nebula, NGC 7009, just above the “bikini bottom” of Capricornus in southwestern Aquarius. I was determined to find this, too, and was eventually able to, 1 degree west of Nu Aquarii. A beautiful dim, fuzzy likeness of its namesake, the Saturn Nebula is an optical delight.

We were then off to the Dumbbell, M27, and what a nice showpiece this is, the brightest Messier Object in the catalog. The dual lobes coming off of this “side view M57” was quite nice, with the elliptical halo surrounding the whole thing clearly visible in my scope.

Then everyone went a little Andromeda crazy, and who can resist M31/32/110 in the eyepiece, the Great Andromeda Galaxy holding celestial court with his two attendant dwarf galaxies? A great view and in my ES 28mm 68*, the dust lane on M31 was visible. Very nice to behold in anyone’s telescope, the Andromeda Galaxy has got to be THE fall celestial spectacular. It’s not to be missed if you don’t get the chance to observe often.

I went after M33, the Pinwheel galaxy, but by this time, fortunately, Jerry’s scope was up and running. It looks good in my 8”, but this faint gem is meant for aperture, and Jerry’s 10”, combined with his above average mirror really turns up the quality of the image — like Spinal Tap‘s Nigel Tufnel said, “goes to 11” . The swirls of the arms, only hinted at in my scope, were there to behold in the XTi 10. Such a nice view!

Then we were off to the Double Cluster, NGC 884 & 869 betwixt Cassiopeia and Perseus’ helmet. Jerry preferred the view in his ES 20mm 100 degree eyepiece, and I had to agree the view was very impressive. I liked the view in mine with the 2” ES 28mm 68*, but Jerry’s seemed to encompass about the same area with higher magnification. Both views were good, but Jerry’s 10” XTi stole the show again, as it is apt to do with the extraordinarily good mirror that scope has.

At Cassiopeia, Darien, who was imaging a target in Cassiopeia, became the Ethiopian Queen’s advocate, evangelizing me to find other delights there, more than a couple I was unaware of. First, of course, I showed off Eta Cassiopeiae, the beautiful contrasting double my eye caught as white to orange — but everyone sees this beauty differently. BTW, this is a fairly close star in our night sky, only 19.7 light years away, with the primary being very similar to our own sun. So our own Sol would appear very much like Eta Cassiopeiae in the night sky on a planet around that star.

At Damien’s encouragement, I uncovered the haunting NGC 7789. This open cluster has a ghostly appearance because, though filled with many stars, it is 8000 light years away and somewhat dim, but rich. This is Caroline Hershel’s “White Rose” cluster, discovered by her in 1783 with her brother William adding to his famous Hershel catalog; definitely worth taking in. Thanks, Darien! Again at Darien’s urging, I was off to M52, another open cluster off Caph, Beta Cassiopeiae. Much brighter than NGC 7789, it’s another nice find in the neighborhood. These two are great fall fare, not to be missed, and rather easy to star hop to from Caph, which acts as a guidepost.

I finished my Cassiopeia course with NGC 457, the ET Cluster. This one lives up to its name, and everyone enjoyed seeing ET with outstretched arms, ready to visually embrace you! Katia, even got Dmitri to put this one in his 130mm reflector, one nice image! Their little scope puts up a nice, wide field, and does such a great job on this target, in particular, and other large targets, too, like the Andromeda Galaxy set.

After Cassiopeia, we put on our UHC/O-3 filters and dove into the massive Veil Nebula (NGC 6960 & 6995), a 3 degree wonder. 6 times the diameter and 36 times the area of a full moon in the sky, this nebulous remnant is what’s left of a star that went supernova sometime between 6000BC – 3000BC. It was glorious going over the filaments and textures, which wouldn’t fit in my ES 28mm 68*, and not even in Jerry’s ES 30mm 82* eyepiece, but what a beautiful journey to navigate through it with our relatively smooth moving dobs. Just south of Epsilon Cygni, the Veil is a hallmark of the Summer/Autumn skies.

I removed my O-3 filter and went back to regular light targets, while I let Jerry borrow my 2” filter, so he went after NGC 7000, the North America Nebula. “Florida and the Gulf of Mexico” were quite evident. A nice view from the Gott, which has a lot of stray light from our fair city to the south.

I dove into the Pleiades, a bit cramped in my ES 28mm 68* in my Z8, but just fits. This is a better target for a smaller, shorter focal length instrument, but it was there, and Jerry was finding NGC 7000.

Jerry made one more Cygnus effort pulling NGC 6826, the Blinking Planetary, out of the inky darkness. The “blinking” quality of this nebulous star is quite striking! Don’t miss it.

After this, we went after Mirach’s Ghost, NGC 404. This happened to be the APOD (Astronomy Photo of the Day) for 27-Oct-2017!
Rather appropriate for Halloween, the distant, dim 10 million light year elliptical galaxy haunts the bright Mirach, Beta Andromedae, a mere 200 light years distant.

From here it was a quick jaunt over to Gamma Andromedae, Almach, a beautiful, colorful double star not to be missed if you find yourself in the neighborhood. Somehow I forgot to split Delta Cygni, but it was getting late.

While I dug up M36 from the eastern muck — low, low in the east — Jerry and Damien put NGC 7331 in the eyepiece, a beautiful spiral galaxy, slender and seen not quite edge-on, but at a glancing angle, near Matar, Eta Pegasi.

It was quite late, and time for me to pack up and head home. Sunday evening is not when we typically observe, and getting up early and being at work is a rather sobering prospect as the hours click off, but it had been months since we went out last. That last time, Ruben and Mark and I were almost carried off by clusters of mosquitoes that molested us relentlessly the entire evening this past Summer at Emma. Although they were present, and Damien was attacked when he arrived much earlier, they decreased such that the night was substantially more enjoyable than my last outing so many months ago.

As we tore down and packed up, Jerry couldn’t resist dialing in Uranus’ location on his Intelliscope object finder. And find it he did! Near Omicron Piscium right now, Uranus was a beautiful aquamarine dot, clearly not stellar, in Jerry’s XT10i, which sent us off into a deep, peaceful place to prepare us for our beds.

Our Saturday night pre-Halloween observing fest at the Emma Cemetery featured Gary’s Scarry Pumpkin and his brother, two Jack-o-laterns with variable LEDs, to help set the scary mood, observing at a cemetery. Unfortunately for me, I was the one to be haunted, by bad collimation issues relating to a “floppy” mirror. The previous weekend, I’d collimated my dobsonian with both lasers agreeing she was well collimated. Okay. So I haul it out to Emma, set it up, and check the collimation, and it’s in need of some adjustment. Well, about 30 minutes later I tried to see if my dob was collimated, getting conflicting results from my Far Point versus my Hotech collimating lasers. As Charlie Brown might say in the Great Pumpkin, “Oh brother”.

While I spun my fingertips on lock screws and adjusted with a Phillips head screwdriver, birthday boy Jerry Hatfield gave us NGC 253, the bespeckled Sculptor Galaxy. Jerry then showed us the Helix Nebula, NGC 7293, in Aquarius, followed by NGC 7009, the Saturn Nebula, also in Aquarius, but about where the belly button might be above the Capricornus bikini bottom.

But then Hatfield shows me his excellent 10” XTi’s beautiful, clean split of the Double Double through his dob with the ES 8.8mm 82* eyepiece at a mere 136 power. Through my own 7mm DeLite, an eyepiece which always splits them in my C102GT, they were fuzzy snowmen. It wasn’t really all that cold, so thermals weren’t likely to have been a big deal. Poor collimation only rendered double trouble. This set off a second round of collimation, which ended when I noticed my laser moving out of collimation as I changed the altitude of my dob. Something was wrong, and I wasn’t going to be able to fix it. I resigned myself to low power viewing, less sensitive to collimation errors, inserting the ES 28mm 82*, and began to pick out wide angle targets.

And M45, the Pleiades, looked pretty nice in the 8” dob. A bit crowded, but they all fit into the 1.58* true field of view, relatively well corrected at the edge, even at F/5.9 The Andromeda Galaxy family, M31, M32 & M110, all looked very nice in the 8”. The dust lane on the “bottom” looked quite nice, if a little less pronounced than Jerry and Scott’s larger aperture views. We picked up the Triangulum Galaxy next, M33, on the opposite side of Mirach. I did find Mirach’s Ghost, NGC 404, and that was a nice little treat.

Perhaps the most memorable target of the night was NGC 7331, along with the other members of the Deer Lick Group in Scott’s 14” dob. Jerry’s scope made a nice framing, itself, but Scott’s large aperture pulled in the most detail of this collection of galaxies in Pegasus.

Before we left, Gary put Uranus in his SCT with go-to. I really would have enjoyed that, but the collimation blues had sapped all the pleasure out of observing for me, and although the glory of Aquarius would have been easy enough to discern out there, I just didn’t feel like bothering, having been so bothered by my unsuccessful scope. I’ve been on Cloudy Nights and tried some more things to collimate it correctly. Maybe someday I’ll get it right and look back on these dark days as growing pains, but that’ll take more tweaking, and I’ve still got more of that to do.

As we stand poised for our November Club meeting, I want to thank Maurice Clark for sending us some astrophotos he nabbed in Australia just before our October meeting. Looks like he’s enjoying retirement northeast of Perth.

Tech Terrace on a Monday night, 10-10-2016

Gary Leiker called me on Monday night, October 10th, 2016, to go out to Tech Terrace Park. There was a big gibbous moon in the sky, but we were both ready for some astronomy. I didn’t arrive until about 9:30, but went straightway to setting up and was aligning my finders (red dot and 50mm RA) by 9:45.

I had my Celestron 102GT refractor (97mm clear aperture, F/10.4), while Gary had his Celestron Edge HD 8, and Scott Harris with Lesley had out his NeXStar SE 8 with 2″ visual back. I was very interested in determining the apparent field of view of my 2″ GSO 42mm Superview eyepiece. I had heard it was actually only 55-odd degrees, even though it is advertised as a 65* eyepiece. I centered around a point between Sulafat (Gamma Lyrae) & Sheliak (Beta Lyrae), the “bottom” stars of Lyra in between which lies M57, the Ring Nebula. One could see the tiny nebulosity, even at 24 power in the SV 42. Quite nice. But there was only about a third of a degree or so outside Gamma & Beta Lyrae, so I’m putting the AFOV of the SV42 at about 57 degrees. That’s about it, folks. Not the best news for me, but still a wider true field of view than what the Hyperion 31mm provided.

Scott and Lesley split the beautiful Eta Cassiopeiae, which I unfortunately missed, still calculating the AFOV/TFOV of the Superview.

But with that out of the way, and Delta Cygni nearby, I decided to try and split that 2.7 arcsecond uneven double. With my BCO 6mm at almost 170x, it split. A bit tight, and wavering due to all the upper atmospheric turbulence we had, but at least it split, at least most of the time.

Epsilon Lyrae, the Double Double, on the other hand, split even in my 11mm Nagler T6.

Scott and Lesley put Albireo in the eyepiece. Plenty of oohs and aahs on that pretty double.

I then put Brocchi’s Cluster, the Coathanger, into my scope. Scott tried it with my SV 42mm, but it’s just too big for an SCT, even with a widefield 2″ eyepiece. Gary’s still got to buy a 2″ visual back for his Edge HD 8.

I put M31/32 into the eyepiece for some reason, nostalgia I suppose. It was there (no M110 of course), but Scott put it in his 8″ SCT and we could make out the cigar shape, even with the glare of the moon! My refractor showed two blobs, but Scott’s gave the galaxy some form. In the neighborhood, I split Almach, Gamma Andromedae, with my 11mm Nagler. What a nice orange-yellow, blue-green combination it was. That inspired Scott to put it in his SCT. Quite a nice one.

That’s when Scott pulled the night’s coup. His tracking impeccable, he put Uranus into the eyepiece of his NeXStar 8. Uranus! In Pisces! On a gibbous moon night! I couldn’t make out ANY stars in that huge southeastern swath of sky. Under Luna’s unforgiving glare, no star dared shine. But the NeXStar tracked right to it. He focused and called us over. Yipee! Third largest planet in the solar system, aquamarine orb, at our service. Hot diggity! This was completely unexpected by me, and gazing at the washed out southeastern skies at Tech Terrace Park I was genuinely impressive.

Scott attempted to do the same thing with Neptune, but Neptune is more finicky, and the skies weren’t exactly cooperative this Monday night. He might have put it in there, but honestly, it wasn’t all that clear. Was it Neptune? Probably. Could it just as easily been a mistaken star? Less likely, but just not certain. Neptune can do that. It’s really a deflating thing to see, knowing how grand it is, fourth largest and all, yet still hard to distinguish from a pinpoint star, unlike the certain orb of Uranus earlier. I’ve always felt that way about Neptune. Even when you KNOW you’ve got it, you’re always kind of scratching your head at its stellar quality, how genuinely tiny it is, and not too planetary looking. Oh well, the turbulence was, indeed, bad, and Neptune wilts plenty under these circumstances.

Gary managed to get a bit of resolution on M13, with a few stars shining about the gray mess of sky the moon grudgingly allowed us.

It was late and we were ready to go, so if you can’t beat ’em, join ’em. Luna demonstrated the turbulence of the atmosphere in the eyepiece, features literally washing about like rocks “moving” through the reflections of a creek bed. She was 10 days old, but quite beautiful …


We packed up and left, satisfied with an evening under the stars, but eager for another.
