William Herschel discovered NGC 7800 = H II-10 = h2291 on 24 Dec 1783 (early sweep 62) and noted "a nebula, vF, E. Has two or three places in which I suspect vF stars." On 18 Sep 1786 (sweep 590) he logged "F, E, bM, pL, the extension not far from the meridian; from sp to nf." John Herschel apparently observed this galaxy on his first sweep of 2 Nov 1823, but didn't identify it later. On 12 Sep 1828 (sweep 175), he logged "F; S; E; irreg fig; 18"."

400/500mm - 17.5" (8/8/91): moderately bright, fairly small, elongated 3:2 SW-NE, weak concentration. A mag 13.5 star is 1.6' ESE and a mag 14.5 star is just off the NE end, 1.5' NNE of center.
