John Herschel discovered NGC 782 = h2454 on 27 Oct 1834 and logged "pB, pL, lE, attached to a star 12th mag." His position is accurate.
600/800mm - 25" (10/15/17 - OzSky): at 244x and 397x; fairly bright, moderately large, slightly elongated WSW-ENE, ~1.0' diameter. Contains a central "bar" oriented ~E-W within a brighter quasi-stellar nucleus. A mag 14-14.5 star is superimposed at the northeast end of the galaxy with the nucleus WSW [by 28"]. A thin, low surface brightness spiral arm is attached at the east end of the galaxy. It was occasionally glimpsed, extending towards the southwest and separating from the central region.
