William Herschel discovered NGC 5710 = H III-895 = h1856 on 20 Apr 1792 (sweep 1021) and logged "vF, vS." CH's reduction is just 5 sec of RA west of UGC 9440. JH made the single observation "eF; S; vgbM; the p of 2 [with NGC 5711], close to a double star [HJ 2737]."

400/500mm - 17.5" (6/20/01): fairly faint, fairly small, round, 1.0' diameter, brighter core. A close double star lies 2.5' SSE. Forms a pair with NGC 5711 3.5' SSE (past the close double).
