William Herschel discovered NGC 2650 = H II-908 on 30 Sep 1802 (his last sweep 1112) and recorded "pB, pL, easily resolvable. I believe I see some of the stars. Irregular figure." His position (Caroline's reduction) and description matches UGC 4603. This galaxy was not included in WH's third catalogue as it was discovered after his 500 discovery threshold was reached on 26 Sep 1802. JH added it in the appendix to his CGH catalogue as one of 8 "HON" (Herschel omitted Nebulae) and he included it in the GC as H II-908 = GC 1690.

400/500mm - 17.5" (2/2/02): faint, fairly small, elongated 4:3 ~E-W, 0.6'x0.4', even surface brightness. A mag 14 star is at the east end [23" from center] and a fainter mag 14.5 star is just off the north edge [33" from center]. Located 7.6' W of mag 7.3 SAO 6667.
