John Herschel discovered NGC 7655 = h3991 on 24 Jul 1835 and recorded "eF and feeble, if a nebula; pslbM; vS; R; 10". It follows a large star." His position and description matches ESO 077-018. DeLisle Stewart described this object as a "group of stars, not a nebula" (repeated in the IC 2 Notes), based on plates taken at Arequipa. As a result, The RNGC misclassifies this number as nonexistent.

600/800mm - 30" (10/15/15 - OzSky): at 303x; fairly bright, very small, round, 18" diameter. Contains a very high surface brightness core surrounded by only a small halo! Situated 2.3' ENE of mag 9.1 HD 220649. A quartet of IC galaxies (IC 5320, 5321, 5323, 5324) lies 15' NE. NGC 7633 is 30' NW.
