William Herschel discovered NGC 4061 = H III-394 = h1065 on 27 Apr 1785 (sweep 403) and recorded "Six nebulae. The times and numbers belong to the three first [III-391, III-392 and III-393]; but I saw three more [10 or 12'] south of them. They were are all vF, vS." I suspected many more besides." The three nebulae which he did not measure positions, are likely NGC 4061, NGC 4065, and NGC 4076 (the three brightest). John Herschel observed NGC 4061 on 3 sweeps and logged on 25 Mar 1830 (sweep 244), "vF; a double neb by diag, pos 20° sp, nearly equal. They run together."

NGC 4055 = h1062, recorded by JH on 29 Apr 1832 (the same night he logged NGC 4057 = h1063 and NGC 4059 = h1064) is very likely a duplicate observation. See that number for more.

400/500mm - 17.5" (3/28/87): fairly faint, small, almost round, brighter core. Forms a pair with NGC 4065 1' ENE within the NGC 4065 cluster.

600/800mm - 24" (3/22/14): fairly faint or moderately bright, fairly small, round, 25" diameter, brighter core but not as strongly concentrated as NGC 4065 just 1.1' ENE. These form a striking pair with NGC 4065. Nearby lies NGC 4072 ~3' SE and NGC 4076 7' ESE.
