Heinrich d'Arrest discovered NGC 7430 on 27 Aug 1864 with the 11-inch refractor at Copenhagen. His position (measured on 2 nights) is an exact match with CGCG 405-019 = PGC 70106 and he mentioned the faint double star just over 1' south.
400/500mm - 17.5" (8/21/87): very faint, very small, round, brighter core. A faint star is very close south. Located 32' E of 50 Pegasi (V = 4.9).
