William Herschel discovered NGC 7634 = H II-441 = h2234 on 26 Sep 1785 (sweep 442) and noted "F, S". JH made the single observation (sweep 281), "a double star with some singular nebulous appendage. The stars are 14m." One star is certainly on the south edge and the other is probably the nucleus. At Birr Castle, Samuel Hunter was uncertain if the star at the south edge was nebulous, but on his third observation in 1862 noted "I think there is no neby round the * adjoining it."

300/350mm - 13" (11/5/83): fairly faint, small, slightly brighter core. A star is off the south edge.

400/500mm - 17.5" (9/14/85): moderately bright, very small, small bright core, round. A mag 14 star is close south 20" SSE of center. Located 40' N of NGC 7619/NGC 7626 in the Pegasus I cluster.
