Steve's Notes
=====
NGC 7840
48" (10/24/11): at 610x appeared faint to fairly faint, fairly small, slightly elongated NW-SE, 24"x20", low even surface brightness. Located 5.3' NNW of NGC 3 and 3.9' WNW of NGC 4.
18" (10/21/06): marginal galaxy in the NGC 3 group only glimpsed with averted and concentration, though it seemed to pop into view at the same location on a couple of occasions as a stellar or quasi-stellar knot. Located 4' NE of NGC 7837/7838 and 5' NNW of NGC 3. Incorrectly classified as nonexistent in the RNGC.
