William Herschel discovered NGC 4756 = H III-281 = h1464 on 8 Feb 1785 (sweep 372) and noted "vF, pS, resolvable." CH's reduction is less than 2' southwest of PGC 43725.

400/500mm - 18" (5/28/06): fairly faint, fairly small, elongated 4:3 SW-NE, 1.0'x0.7', broad mild concentration. A mag 14.5-15 star is at the NE edge. Brightest in a cluster (LGG 306) superimposed on AGC 1631. A total of 10 galaxies in both clusters were tracked down.

18" (4/29/06): moderately bright, moderately large, elongated 5:3 SW-NE, 1.3'x0.8', broad concentration. Brightest galaxy in a galaxy group (LGG 306) superimposed on AGC 1631 and situtated near the center of the cluster. Several faint galaxies are visible in the field including a trio ~8' SW.
