William Herschel discovered NGC 4798 = H II-382 = h1477 on 11 Apr 1785 (sweep 396) and noted "F, pS." WH was rapidly on his way to discover 74 galaxies in this sweep, so for the next several objects he gave very brief descriptions. JH made two observations and measured an accurate position.

400/500mm - 17.5" (5/14/94): fairly faint, fairly small, slightly elongated N-S, very weak concentration. A mag 14 star is 1.0' S of center and a mag 10 star 7.5' E. Member of AGC 1656 with NGC 4788 10.9' SW, NGC 4807 9.9' NE and IC 3900 14.5' SE.
