Steve's Notes

===== NGC 7803 48" (10/24/11): at 610x appeared bright, oval 3:2 WSW-ENE, 0.8'x0.5'. Sharply concentrated with a very small, very bright core. A 17" pair of mag 14.4/15.1 stars is 1' NW. Flanked by HCG 100B 1.5' E and 100D 1.2' W. All 4 galaxies in HCG 100 fit within a circle of radius 2'. In addition, MCG +02-01-013, an extremely faint galaxy, lies 1.2' SE of 100D and Mrk 935 lies 4.7' ESE of 100D. 18" (9/24/05): fairly faint, fairly small, elongated 2:1 ~E-W, increases in size to ~0.8'x0.4' with averted vision. Contains a small, brighter core that is rounder. A faint pair of mag 14/15 stars lies 1' WNW. Precedes a mag 11 star by 2'. Forms a close pair with HCG 100B, which appeared very faint, elongated 3:2 NW-SE, 0.3'x0.2'. Sandwiched between NGC 7803 1.5' W and a mag 11 star less than 1' following. 17.5" (11/10/96): fairly faint, fairly small, elongated nearly 2:1 WSW-ENE, brighter core. A pair of mag 14/15 stars lie 1' WNW. This galaxy is the brightest in the compact HCG 100 group. Forms a close pair with HCG 100B 1.5' E. The fainter companion is very faint, small, round, 0.4' diameter. Sandwiched between NGC 7803 1.5' W and a mag 11 star 46" ENE. 17.5" (9/15/90): faint, small, elongated 3:2 WSW-ENE, almost even surface brightness. A pair of mag 14 and 14.5 stars is 1' WNW. Collinear with two stars mag 12.5 and mag 11 2.3' E and 4.0' E, respectively. NGC 7810 lies 18' ESE.
