William Herschel discovered NGC 1924 = H III-447 on 5 Oct 1785 (sweep 458) and recorded as "vF, pL, R, within 2 or 3' of the corner of a hook of vS stars." It's interesting he classified this galaxy as a cluster. His position is 3.6' south of MCG -01-14-011 = PGC 17319. George Bond independently found this nebula on 7 Feb 1863 at Harvard College observatory with the 15-inch Merz refractor and measured an accurate position (#12 in the HC discovery list in AN #1453).

400/500mm - 17.5" (11/25/87): moderately bright, moderately large, slightly elongated. Located 6.7' SE of mag 8.5 SAO 1321324 and 9' NW of mag 8 SAO 132149. M42 lies just two degrees east!
