Heinrich d'Arrest discovered NGC 7710 = m 586 on 24 Sep 1862 with the 11-inch refractor at Copenhagen. Albert Marth independently found this galaxy in Nov 1864 and noted "vF, vS, stellar."

400/500mm - 17.5" (12/16/95): faint, small, 40"x30" halo extended NW-SE, broad concentration to a slightly brighter core. Situated in a poor star field at 220x with only scattered mag 14-15 stars. Located 19' following NGC 7701 (which is the brightest of a trio).

600/800mm - 24" (9/22/17): at 260x; fairly faint to moderately bright, fairly small, very elongated 7:2 NW-SE, 0.8'x0.25', well concentrated with a small bright core. NGC 7701 (brightest in a group) is 19' WNW.
