William Herschel discovered NGC 3796 = H II-839 = h937 on 19 Mar 1790 (sweep 953) and recorded "pF, cS, R, mbM." CH's reduced RA is 27 tsec too large. JH made two observations, noting on sweep 406 "pB; R; 35"; pgbM." His position is within 1' of UGC 6638.

400/500mm - 18" (3/5/05): moderately bright, fairly small, slightly elongated NW-SE, 0.6'x0.5', increases to a very small bright core and a stellar nucleus.
