William Herschel discovered NGC 3687 = H II-770 = h895 on 22 Feb 1789 (sweep 909) and noted "pB, pL, R, lbM." His position matches UGC 6463. JH made 5 observations.

400/500mm - 18" (3/29/03): fairly faint, fairly small, round. Seems to have an irregular surface brightness with a very small, slightly brighter condensation in the halo.
