John Herschel discovered NGC 6631 = h3746 on 12 Jul 1836 and recorded "cl VII class; p rich; 5' diam; with appendages, st 12...15m. Much richer than any part of the milky way seen tonight."

200/250mm - 8" (7/16/82): a dozen stars were resolved over unresolved haze. A double star mag 11/11.5 at 10" is at the south edge.

400/500mm - 17.5" (7/1/89): at 220x about 40 stars are resolved in a 5' region over unresolved background haze. A mag 11 star is at the NW edge but most stars are mag 13/14. Includes an equal mag 11.5/12 double star off the SE edge. Barnard 95, a large dark nebula lies 30' NW.
