The EP is not dead but the thread is !

Posted By George Golitzin

I certainly hope so, but OTOH, someone should nominate Herbert H. for "longest thread starter" or something. Between this one and the "53,000 cave mirrors" over on the reflector forum, he's really got something going this month!

Cepheus spiral, NGC6946

Posted By George Golitzin

Inge-
In my 16" under mag 6 or better skies at 200X I see a great hooking arm on the east side separating into two, and a stubby claw of two arms toward the west; at lower power this detail is enveloped in a slightly oval nebulosity. It helped to have the galaxy near the meridian, for me about 70 degrees of altitude. At home under sub mag 5 skies it is just a smudge, occasionally hinting at some structure in AV. I've looked at it many times in smaller scopes (8, 10, and 13 inch) but (oh the shame!) haven't recorded those observations. It is a very satisfying object to contemplate in the 16", an early autumn consolation, when the spring galaxies have long since set.

Re: one scope only!!!!!

Posted By George Golitzin

Probably this: my 35 pound 10" f/5.6, with swayze primary, antares secondary. Total cost < $850. Leaves room for $1000 in eyepieces, no, better make that $1500 8O , and an eq platform for those planetary nights. It is as easy to carry out as my 4" refractor on a polaris mount (thanks to ed moreno for that suggestion!), has plenty of quality aperture for plantetary/lunar, and does fine on dso. I would miss the depth of my 16" dob and the birding capabilities of the refractor, but realistically, the 10" gets the most use.

What is your favorite EP for galaxy details?

Posted By George Golitzin

Naglers. In my 16" f/5 I generally prefer the 11mm T6 for fainter galaxies--I just seem to get the optimum contrast in a 2 mm exit pupil--but for brighter galaxies I sometimes prefer the 16mm T5. For example, the 16mm gave me the better view of the spiral arms of M81 a while back. The sharp wide field of both really helps in finding the fainter objects, as well as increasing the pleasure of the view.

Can you see these galactic details?

Posted By George Golitzin

Hi Inge--

You should add "spiral arms of m 81"--but I guess it's too late now. The answers below refer to my 16" under mag 6 or better skies, unless otherwise noted.

1: Dust bands in M82 A
2: Spiral arms of M61 C
3: Equatorial dust band of NGC891 A
4: Spiral arms of M33 A
5: The obscuring cloud of M64 ("Black eye") A
6: Spiral arms of M51 A
7: Emission nebula, NGC604 in M33 A (seen in an 8")
8: Dust bands in NGC3556 You mean M 108? C
9: Spiral arms of M99 C
10: One dust band in the Andromeda galaxy A (seen in 8")
11: Spiral arms of M101 A
12: Equatorial dust band of NGC3628 (The one near M65/66) A
13: Two dust bands in the Andromeda galaxy A
14: Emission nebulae in the spiral arms of M101 A
15: Spiral arms of M100 C
16: Equatorial dust band of NGC4565 (Coma Berenices) A (seen in 4" refractor--very good sky)
17: "Bend" of galaxy NGC4656 (Canes Venatici) A (a favorite along with its big neighbor 4631)
18: Spiral arms of NGC2403 C (I've only looked at this at home under perhaps mag 5 skies--should try it under darker skies...)
19: Spiral arms of NGC2903 C (again, I always seem to be looking at this at home, and not at my dark sky sites...)
20: Bridge between M51 and companion galaxy A

best wishes,
George

Scope/Eyepieces/Barlow

Posted By George Golitzin

Steven--it kind of depends on whether you intend to get any more eyepieces (or have some lying around)--the 8mm hyperion would be a natural progression from the 21 and 13, in which case, a 2X barlow would yield focal lengths of 10.5, 6.5, and 4, a nice choice of magnifications. But if you don't intend to get something like the 8mm down the road, then I'd go for the stronger barlow. Both have good reps. For my part, if I'm willing to spend $60 used on an orion or u.o. barlow, I'd probably prefer to drop an extra $10 and get a televue, but I admit I'm a sucker for the televue cachet. More to the point, there's no real reason to get a shorty barlow for a newt that I can see. But maybe you have refractor or cat plans in the works. One more thing--I'd be shooting for something to get up around 300X now that Saturn is coming around, and well placed too, if not so nicely tipped as in the past few years. The 8mm with a 2x barlow would do just that.

Vixen Eyepieces?

Posted By George Golitzin

I can't comment directly, but here is a link to a detailed review comparing the baader hyperion and orion stratus line to the vixen lvw, in several focal lengths; apparently the baader and orion were modeled on the vixen; overall, the reviewer gives a slight edge to the vixen eyepieces.

Burn-out?

Posted By George Golitzin

Ok, Inge, you asked for it. Here's a long one featuring the southern beauties 1365, 1300, and 2477, or,

"How I Spent the Night Sitting on the Dirt."


OR 1/19/07—Lake Sonoma, north of Santa Rosa, CA. Seeing quite soft, transparency good, about mag 6. 16” f/5 dob with 27 Panoptic, 16 and 11 mm Naglers.

This appeared to be my last chance this season of a good look at ngc 1365, which I had only glimpsed once, a year and a half ago, in the pre-dawn twilight of a late August morning. Trusting in the clearskyclock, I got on the road with an hour to spare—an hour that evaporated due to a bad accident on the highway ahead of me—and I arrived about 5 minutes before the galaxy was to transit—about 7:50 local time. So I drove the last 20 minutes with a ski mask over my right eye (probably not a good idea, but I really wanted this target) and achieved a personal best for setup and collimation!

I’m not familiar with this part of the sky, and it took a few minutes to identify the two groups of upsilon-eridani, which point toward a little triangle of mag 4.5 stars (sao 194559) about 3 deg east of 1365: this group was just visible, about 15 degrees above the horizon—I was fighting the light-dome from Santa Rosa. Once I had these, the galaxy was easy to find: it showed a bright E-W bar of 5’ extent, perhaps tilting toward the WSW; the arms extended N/S from the end of the bar another 5’ each. A faint (mag 13, I guessed) star was at the tip of the northern arm—well, I didn’t quite see the arm extend this far, about 8’—I intuited it in AV with a little shaking of the cage, and may have imagined the glow of an HII region nearby—another mag 13 star nestled in the juncture of the bar and N arm about 1.5 to 2’ NW of the core; and a pair of similar stars 6’ ENE of the core were arranged N/S sep 1.5’ or so. The galaxy was best in the 16mm, though a little washed out; the 11mm did not quite let enough light in—it was one of the few times I wished for something in between (sigh). The N arm was much easier, though both arms were strongly suggested at the “corners” where they leave the bar. The S arm required AV, esp in the 11mm. This must be a spectacular galaxy in large apertures from a southern location.

To the south I spotted 1326 (sm., f brt, rd) and the pair 1316 and 1317 (1317 quite bright, 6’ south of 1316, v sm and ft.) and to north I found 1350, a hazy oval. A quick perusal (in my 27mm) of the Fornax I cluster nearby yielded 10 galaxies in a 2 degree circle—I was too lazy to dig out my detailed charts and make IDs, and I was anxious to go north to ngc 1300.

1300 appeared 5 to 6’ long, roughly EW, by 3 to 4’ high. At first glance, it seemed oval with a bright bar running the full 5’, but mottling on either side of the bar helped to define the arms, which curve back, running parallel to the bar EW on the north and south. The W edge of the northern bar is particularly well defined, but overall the S arm is brighter. The nucleus was stellar, at least in this poor seeing. Another fine galaxy.

I turned to Puppis, first to look at M46—the PN 2438 was very bright in the 11mm and showed its ring structure), and then to find 2477, a rich OC far to the south. A week ago I was in Kauai on a family vacation, with my trusty 8x40’s, and I spotted this cluster, about 2 degrees NW of zeta-puppis, not knowing its identity—clearly an open cluster, but very bright and compact, almost like a big globular in the little binoculars, and I figured it had to be a nice target in any telescope. At Lake Sonoma, it was just 10 degrees off the horizon in the heart of the Santa Rosa light dome—the only visible reference star was pi-puppis, 7 degrees to the WNW. In my binoculars I was able to identify ngc 2451 (very coarse, large, close OC), about a degree from 2477 and so point the scope. Well, it was very washed out in the glare, but evidently very rich, compact OC of about 15’ diameter, a little oblong. It must be a beauty in southern skies, perhaps comparable to M 37.

Other objects visited: Orion: M42 (duh! Fabulous, the wings curved around into a full circle of about 50’ diameter, broken only toward iota-Ori—when I placed the trapezium at the edge of my 16mm, the entire field of 40 minutes was filled with nebulosity of varying density); ngc 1977 et al, the nebulosity around the northern part of the sword, very pronounced, running EW in layers; the flame nebula (2024) very bright, in two lobes separated by a N/S dark streak, the easterly lobe showing 3 dark fingers--I preferred the unfiltered view in the 16mm to the UHC; 2023, a bright nebula about the mag 8 star sao 132464 just south of zeta-Ori near the horsehead. Ursa Major, galaxies near the two paws: 2639, NE of iota-UM, f brt, elong 2:1, and little (mag 13) 2684, a smudge 1 deg NW of iota-UM; at the southern paw, just W of mu-UM, 3184, a face on spiral: it showed (in the 16mm) a circular, fairly bright, featureless haze of 7’ diameter, with slight central brightening. And of course M81 and 82.


Best wishes,
George

p.s. I finished at 10:30 with a look at Saturn. It was a mess. I guess the moral is you can have a lot of fun even with mediocre seeing.
