William Herschel discovered NGC 5492 = H II-876 = h1754 on 20 Apr 1792 (sweep 1021) and recorded "pB, vS." His position is just off the south side of UGC 9065. Stephan independently found this galaxy and reported it as new in list XII-58, but used a poor position for the offset star so his position was off. In the notes to list XII, Stephan comments his object is probably identical to NGC 5492. Esmiol's "corrected" position in his 1916 re-reduction is exactly 1' off in declination (matches in RA).

400/500mm - 17.5" (5/11/96): this nice edge-on is elongated 5:1 NNW-SSE, 1.6'x0.3'. Moderate surface brightness with no significant central brightening. Located 14' SE of mag 7.1 SAO 100885.
