William Herschel discovered NGC 7619 = H II-439 = h2230 on 26 Sep 1785 (sweep 442) and recorded "vF and vS." His position is accurate. John Herschel made two observations, reporting "pB; R; bM; 30"." (sweep 89) and "B; pL; R; psbM." (sweep 280)

NGC 7619 was the most distant known galaxy mentioned by Hubble in his 1929 paper "A relation between distance and radial velocity among extra-galactic nebulae", although it's recessional velocity of +3779 km/sec wasn't used in his graph of the velocity-distance relationship. Hubble mentioned a preliminary distance of 25 million l.y.

200/250mm - 8" (9/25/81): faint, small, small bright nucleus.

300/350mm - 13.1" (9/22/84): bright, small prominent core, largest in cluster.

400/500mm - 17.5" (9/14/85): bright, elongated, bright core, stellar nucleus. This galaxy is the brightest and largest member of the Pegasus I cluster along with NGC 7626 6.9' E. Forms a close pair with NGC 7617 2.8' SSW. NGC 7626 lies 11.0' E and difficult UGC 12518 lies 9.4' NW.
