David Todd discovered NGC 3685 = Todd 9 on 11 Dec 1877 in his search for a trans-Neptunian planet (AN 2698). I was unable to identify this object but Corwin found a match with CGCG 039-192. He describes this as "the higher surface brightness component of a pair of CGCG galaxies; the other is UGC 06466, a pretty low surface brightness barred spiral." I confirmed Todd's offsets for the nearby stars, so this identification is certain. The RNGC classifies the number as nonexistent, though NED and HyperLeda use this identification.

400/500mm - 18" (4/30/11): faint, very small, round, 20" diameter. Forms the western vertex of a triangle with two mag 13 stars 2' NE and 2' E. Forms a close pair with UGC 6466 just 1' SW, but I wasn't convinced this low surface brightness spiral was glimpsed.
