John Herschel discovered NGC 1764 = h2713 on 2 Jan 1837 and described as "very faint, small, round, 15". The zone here is full of grouping and clustering stars." His position is accurate.
600/800mm - 24" (11/18/12 - Magellan Observatory, Australia): relatively bright, fairly small, round, 0.4' diameter. At 200x, a few very tightly packed stars are resolved within the glow. A mag 14.2 star is 0.6' S and a mag 12 star is 2.2' SW. NGC 1786 lies 15' ESE.
