William Herschel discovered NGC 2763 = H III-275 = h560 on 8 Feb 1785 (sweep 371) and reported "vF, vS, bM, about 1/2' south of a small star." His position was 3' too far north. On 16 Dec 1827 (sweep 111), John Herschel logged, "eF; pL; has a small star just north, and four more preceding." His position and description was accurate. The Slough Catalogue has a typo; read H. III-275 for H. II-275. He corrected the error in the General Catalogue.

400/500mm - 17.5" (3/28/87): moderately bright, fairly small, slightly elongated, weak concentration, diffuse outer halo. A mag 12.5 star is close off the north edge 1.2' from the center.

600/800mm - 25" (3/31/19 - OzSky): at 244x; fairly bright, large, slightly elongated 5:4,~2.0'x1.6', brighter core gradually increases to the center, faint stellar nucleus, diffuse outer halo (face-on spiral). A mag 13.0 star is at the north edge with a fainter star right at the north edge.
