John Herschel discovered NGC 7757 = h2270 on 24 Sep 1830 and recorded "vF; pL; R; vglbM; 40"; a * 13m, 1' N." His mean position (2 sweeps) is accurate. On 11 Dec 1873, it was described at Birr Castle as "vF, cL, lE, shaped like an "S" backward." So, clearly he noticed the brighter spiral arms. Arp (68) and CGCG misidentify this galaxy as NGC 7756. See that number.

300/350mm - 13.1" (11/29/86): faint, small, round, diffuse, even surface brightness. Collinear with two mag 12 and 13 stars 1.3' N and 2.5' N, respectively. Located 13' E of mag 7.7 SAO 128385.
