Steve's Notes

===== NGC 4922 18" (4/30/11): fairly faint to moderately bright, fairly small, elongated 3:2 N-S, ~50"x30", irregular shape, small bright core. After careful viewing this interacting galaxy consists of a brighter component on the south side, perhaps 30" diameter and punctuated by a bright core. A very faint low surface brightness glow is attached on the north side (PGC 86794), extending perhaps 20". A string of stars extends to the southeast with a mag 12 star 1.4' ESE. NGC 4916 (see identification notes) lies 9' SE 18" (3/30/05): fairly faint, fairly small, elongated 3:2 ~N-S, 0.7'x0.4'. On sustained viewing, what appears to be the core or a compact galaxy, ~0.3' diameter, is on the SSW end. A much lower surface brightness glow extends to the NNE, mimicking the appearance of a tiny comet. Member of AGC 1656 (Coma Galaxy Cluster). A mag 12 star lies 1.4' E. Checking at home I found this was a double system (NGC 4922A = southern member, NGC 4922B = northern member) in a common halo with the brighter component on the south end so the visual description is fairly accurate.
