William Herschel discovered NGC 3805 = H III-375 = h941 on 25 Apr 1785 (sweep 401) and logged "eF, S, but strong twilight and moonlight make it impossible to describe it properly." JH reported "Not vF; S; R; bM." and measured a fairly accurate position.

400/500mm - 17.5" (4/15/93): fairly faint, small, elongated 4:3 SW-NE, small bright core dominates a small halo. A mag 13 star is 2.2' WSW. NGC 3787 lies 16' NW. Located at the western edge of AGC 1367.
