400/500mm - 18" (10/8/05): extremely faint, very small, round, 0.2' diameter (only core seen?). Requires averted vision to glimpse. A very close (generally unresolved) pair of mag 15-15.5 stars lies 2' N. Located 4.3' SSE of HCG 2A and faintest of trio.

18" (11/6/04): extremely faint, fairly small, round, 0.8' diameter, very low even surface brightness and requires averted vision. Located 4' SSE of UGC 312 = HCG 2a (faintest of three seen).

900/1200mm - 48" (10/24/11): fairly faint, moderately to fairly large, slightly elongated N-S, 1.0'x0.8', weak concentration to a slightly brighter core. A faint mag 16.9 star is just off the NW edge and a mag 15.4 star is 1' SSE. An 8" pair of mag 15 stars was easily resolved 2' N. HCG 2D lies 2.3' ESE. On the SDSS image, the core is very offset to the following side and the halo appears like a ring.
