Quote:Galaxies are notoriously difficult to observe from my red-zone back yard so when I find one that’s easy to see it’s usually something pretty special. While using my LightBridge 16 to explore southwestern Perseus I was very surprised to find that NGC1023 was very easy to find and clearly showed an elliptical shape. Galaxies of this size usually show nearly stellar cores surrounded by faint, pearly haze. NGC1023 is variously described as either an elliptical galaxy or as a barred spiral, though the later seems to be the more modern and accepted description. What strikes me as interesting about this galaxy is that although its relatively high surface brightness makes in an easy visual object it shows so little detail photographically.Telescope: Meade SC8 @ f/10, Orion Atlas EQ-GGuider: Orion Deluxe Off-axis Guider, DSI Pro III, PHDCamera: Canon Rebel T2i, Orion Imaging Sky Glow FilterExposure: 60x90sec, ISO 3200 saved as RAWDarks: InternalFlat: SyntheticSoftware: Backyard EOS, Deep Sky Stacker, Photoshop

Quote:I've observed NGC 1023 quite a few times in the past several months through apertures ranging from 101 millimeters to 32 inches. The locations, with one exception, had better than sixth magnitude NELMs. Through my 101mm Tele Vue refractor at 79 and 108x, NGC 1023 appeared as a small and rather dim oval, with a somewhat brighter nucleus. The 32" Dob, however, portrayed its faint outer arms rather nicely.
A man is a small thing, and the night is very large and full of wonders.

Quote:OK, here is a cropped version of the image of NGC 1023 and its companion NGC 1023a (along the lower left edge of the galaxy) by Minnesota astrophotographer Rick Johnson (north is at the top). Also visible is the 17th magnitude galaxy PGC 10169 just below the bright star off the left edge of NGC 1023:

Interesting to go picking through the detail..Thanks!
