Lewis Swift discovered IC 810 = Sw. VII-24 on 6 May 1888 and reported "eF; pS; eE." His position and description fits.

600/800mm - 24" (5/24/20): at 375x; faint, fairly small, the central region is ~25"x15" NNW-SSE with a weak concentration. The outer extension have a very low surface brightness and extend 45"x15". NGC 4640 is 22' SE and CGCG xxx is 22' SSW.

24" (6/3/19): at 322x; fairly faint, edge-on 5:1 NNW-SSE, ~1.0'x0.2', pretty even surface brightness except for a very small or stellar nucleus. A 30" pair of mag 11.7/12.6 stars is 5' SE. This Virgo cluster member is located 21' S of NGC 4620 and 22' ESE of mag 7.9 HD 110249.
