William Herschel discovered NGC 4813 = H II-777 = h1482 on 23 Mar 1789 (sweep 916) and recorded "F, S, R, bM." JH reported "S; R: bM; wind violent." but measured an accurate position. Harold Corwin suggests IC 833 may be a duplicate observation (see his IC identification notes).

400/500mm - 17.5" (5/17/90): fairly faint, fairly small, elongated 2:1 SW-NE, small bright core, stellar nucleus. Located 11' NE of a mag 9.5 star.
