Heinrich d'Arrest discovered NGC 2753 on 21 Feb 1863 with the 11-inch Merz-refractor at the Copenhagen observatory. There is nothing at his position (#87 in AN 1500), though he noted a mag 13-14 star was 40" northwest. Exactly 1 min of time east of his position is CGCG 121-020 = PGC 25603, matching his description. He mentioned that he couldn't find this nebula again on nights #173 and 229, so the first position was clearly a recording or copying error.

400/500mm - 17.5" (4/6/02): faint, small, slightly elongated SSW-NNE, 0.5'x0.4', weak concentration. A mag 13.5 star is 1.0' NW. NGC 2750 lies 19' WNW.
