William Herschel discovered NGC 4468 = H II-630 on 14 Jan 1787 (sweep 691) and simply noted "cL". His position is 5' south and 14 tsec west of UGC 7628, but it was observed in the sweep between NGC 4459 and NGC 4474, and this is the only galaxy between these two. Heinrich d'Arrest measured an accurate position at Copenhagen as well as Rudolph Spitaler in 1891 at the Vienna Observatory.

300/350mm - 13.1" (5/14/83): faint, small, diffuse, slightly elongated, no noticeable concentration.

400/500mm - 17.5" (4/25/87): faintest of three with NGC 4474 5.5' ENE and NGC 4459 8.7' SW. Faint, fairly small, slightly elongated ~E-W, small weak concentration.
