400/500mm - 17.5" (9/2/89): very faint, extremely small, round. A mag 11 star is 2.0' N. Forms a pair with NGC 7475 1.6' NE.

600/800mm - 24" (9/10/15): faint to fairly faint, small, round, 18" diameter, stellar nucleus. First in a trio with NGC 7475 1.6' NE (double system with MCG +03-58-028). A mag 11.5 star lies 2' N and a wide pair (~15") is 2.8' SE.
