North is left. 0.35"/pixel (7.7' by 20' field). FWHM = 5.5" Arp filled this under "galaxies with narrow filaments", but I don't really see why. It's a barred sprial with irregular arms and a faint extended disk. That being said, the galaxy's bar is slightly misaligned with the core: which would sudgest that it might have experienced some graviational interaction in the past. The main galaxy is at z=0.0045, and the faint background galaxy in the lower left is UGC 10509 at z=0.055. It's actually a spiral with a really intresting structure, but it's too small (and dim) to see in my image. Total exposure time:274 * 30 seconds = 2.2 hours. Telescope: C9.25 (230mm, f/10, fl=2300mm) Camera: IMX533 (16mm diagonal, square, color) Processing: Callibration (dark + flat) Stacking (average w/ rejection) White balance and background subtraction Asinh stretch Tone curve Crop Taken during a night with exceptionally bad seeing, resulting in a FWHM of 5" instead of the usual 3". Not that I ever get…
