Heinrich d'Arrest discovered NGC 2468 on 1 Jan 1865 and recorded "F, R, lbM. Without doubt one of the LdR nebulae." See NGC 2458 for some background on the Lord Rosse observations on 20 Feb 1851. His single position matches UGC 4110 = PGC 22325.

400/500mm - 17.5" (1/19/91): fairly faint, very small, oval 2:1 SW-NE. A mag 12 star is off the NW edge 1.2' from center. Located 15' SE of mag 6.5 SAO 26579. The NGC 2461-2472 group lies 20' N.

600/800mm - 24" (2/13/18): at 375x; fairly faint, fairly small, elongated 2:1 SW-NE, ~50"x25", very small brighter core and occasional stellar nucleus. A mag 11.4 star is 1.2' WNW. NGC 2468 forms a close pair with LEDA 200240, just 30" SSW of center. The companion appeared very faint and small, 12"-15" diameter and could just be held continuously with averted vision.

UGC 4133 and UGC 4134 is another close pair situated 18' due east. UGC 4134 appeared fairly faint, oval 2:1 SSW-NNE, ~30"x15", nearly even surface brightness. UGC 4133 = FGC 693 is just 1'NW and was a very faint, superthin streak, ~40"x5" oriented NNW-SSE.
