John Herschel discovered NGC 7788 = h2283 on 5 Oct 1829 and recorded a "vS and close cluster. One * 10m with a great many minute stars close to it."

300/350mm - 13.1" (9/29/84): about a dozen mag 12-14 stars over haze in a 1.5' diameter. Includes a single bright star mag 9.3 SAO 20947 on the west edge. This is a small but distinctive group in a very rich field. Situated within a string of open clusters with NGC 7790 and Harvard 21.

400/500mm - 18" (11/26/03): fairly small, 4' rich clump of roughly two dozen stars. Includes a mag 9.7 star (SAO 20947) on the west side. Several other mag 10 stars are scattered nearby but the cluster still stands out fairly well in a rich Milky Way star field. NGC 7790 is situated 16' SE.
