Steve's Notes

===== NGC 93 48" (10/30/16): at 488x and 610x; very bright, moderately large, very elongated 3:1 or 7:2 SW-NE, 1.0'x0.3', well concentrated with an intense core that elongates into a bar with averted vision. A low surface brightness outer halo increases the size to 1.0'x0.45'. Three mag 13.5-14 stars are close following. Forms a striking interacting pair with NGC 90 2.8' WSW. LEDA 1669768, located 1.4' NNW, appeared fairly faint, very elongated 3:1 ~N-S, 30"x10". At a redshift of z = .071 (light-travel time 950 million years) it resides far in the background of the cluster. 18" (11/22/08): fairly faint, fairly small, elongated 5:2 WSW-ENE, 0.5'x0.2', contains a very small brighter core. A triangle of mag 13.5-14 stars follows by 1'-2'. NGC 90 lies 2.8' W. 17.5" (9/19/87): faint, very small, oval SW-NE, faint stellar nucleus, bright core. This is a double system with an anonymous companion 35" S. Three mag 13.5-14 stars follow at 1.2' E, 1.9' E and 1.9' ESE forming a small right triangle. Forms a pair with NGC 90 2.8' W at the east side of the NGC 80 group. 13" (9/29/84): fairly faint, very elongated. There is a trio of very faint stars to the east.
