William Herschel discovered NGC 5760 = H III-885 = h1879 on 24 May 1791 (sweep 1006) and recorded "eF, vS, E nearly in the parallel [E-W]." JH logged "vF; lE in parallel; vglbM." and measured an accurate position.
400/500mm - 17.5" (7/16/01): faint, fairly small, elongated 3:2 WNW-ESE, weakly concentrated. Located 3.4' N east of a mag 10.5 star. Forms a pair with difficult IC 4507 2.9' S.
17.5" (6/16/01): faint, fairly small, elongated 3:2 ~E-W, 1.0'x0.6', weak concentration. IC 4507 2.8' S (mag 15.7z) was not seen with certainty in poor conditions (partially cloudy). HCG 72 lies 32' N.
