William Herschel discovered NGC 5433 = H III-653 = h1737 on 20 Mar 1787 (sweep 722) and recorded "vF, pS, E in the direction of the meridian [north-south], 300 showed it very plainly." JH made two observations and his mean position is accurate.

400/500mm - 17.5" (5/27/95): faint, fairly small, very elongated 7:2 N-S, 1.1'x0.3'. Broad concentration with no nucleus, extensions fade into background.
