William Herschel discovered NGC 5235 = H III-100 = h1644 on 13 Apr 1784 (sweep 191) and logged "eF, E. It follows a star 7-8 mag 6.2 min in time and is 34' more north." JH made three observations, recording on sweep 153 "F; pL; R; very dilute; nf a * 9m."

400/500mm - 17.5" (6/2/00): faint, fairly small, elongated 2:1 WNW-ESE, 0.8'x0.4', smooth surface brightness. NGC 5224 lies 14' SW. Located 3.6' NE of a mag 10 star.

600/800mm - 24" (6/29/16): moderately bright, elongated 5:3 ~WNW-ESE, ~40"x24", contains a relatively large brighter core. A mag 10 star is 3.7' SW and a mag 14.5 star is 1' NNE.

CGCG 045-035 lies 3.6' S and a similar distance southeast of the mag 10 star. It was noted as very faint, slightly elongated N-S, ~15"x10". UGC 8596 lies 12.5' SE and appeared faint, fairly small, slightly elongated NNW-SSE, 25"x20", broad concentration with a slightly brighter nucleus.
