Forms a close pair with CGCG 039-134 1.3' WSW. This galaxy, though a magnitude fainter, is misidentified as IC 683 in many sources. It appeared extremely faint, very small, round, 15", only occasionally popped but verified. Forms a pair with IC 683 1.3' ENE.

Guillaume Bigourdan discovered IC 683 = Big. 162 on 14 Apr 1888. His position matches CGCG 039-138, but CGCG, UGC, PGC, HyperLEDA (and secondary sources such as MegaStar) misidentify CGCG 039-134 = PGC 34793 (just 1.3' WSW) as IC 683. HyperLEDA labels CGCG 039-148 as IC 683E.

600/800mm - 24" (5/20/20): at 375x; faint, small, round, 20" diameter, very small brighter nucleus. Can just hold continuously. Located 3.6' S of NGC 3644.
