John Herschel discovered NGC 7615 = h2229 on 16 Aug 1830 and noted "pF; R; psbM." His position is fairly accurate although this galaxy was missed by d'Arrest (failed attempts in 1862 and 1865), Wilhelm Tempel and Herman Schultz (searched for in vain in 1865).

300/350mm - 13" (11/5/83): extremely faint, at visual threshold, possibly slightly elongated. A mag 14 star is off the edge.

400/500mm - 17.5" (10/12/85): appears slightly brighter than NGC 7608, elongated ~NW-SE. A faint star is off the east edge.

17.5" (9/14/85): very faint, diffuse, slightly elongated. A mag 14 star is off the east edge 1.0' from the center. This member of the Pegasus I cluster is located 6' WNW of NGC 7621 and 7.5' W of NGC 7623.
