Albert Marth discovered NGC 2933 = m 173 on 1 Apr 1864 with Lassell's 48" on Malta and reported "F, vS, lE, sp of 2 [with NGC 2943]." His position is 1' N of UGC 5132 = PGC 27436. This is the 3rd of 7 galaxies discovered that night in the NGC 2943 group. A very faint edge-on is at the NE tip and RNGC, UGC, MCG and PGC identify the system as NGC 2933/2934, but NGC 2934 is more likely a separate galaxy 2.4' N. See that listing.

400/500mm - 17.5" (3/29/89): extremely faint, small, round, very diffuse. A mag 11 star is 1.5' SSW. Located 11' N of mag 7.9 SAO 98681. Forms a pair with NGC 2943 9' E.

600/800mm - 24" (2/22/14): at 375x appeared faint, fairly small, very elongated 3:1 SW-NE, 24"x8", even surface brightness. Situated 1.6' NNE of a mag 10 star and 9' W of NGC 2943, the brightest member of the group (WBL 229). NGC 2934 (faintest member) lies 2.4' N.
