William Herschel discovered NGC 3435 = H II-887 = h781 on 9 Apr 1793 (sweep 1039) and noted "F, pL, bM, iF." His position is 3.8' southwest of UGC 6025 (similar offset as NGC 3407, the previous object in the sweep). John Herschel's RA was 1 minute too small and this error was copied into GC and NGC.

400/500mm - 17.5" (3/19/88): fairly faint, fairly small, elongated SW-NE, bright core.
