William Herschel discovered NGC 4758 = H III-70 = h1465 on 21 Mar 1784 (sweep 182) and noted "vF, not S." CH's reduced position is 6 sec of RA too far west. JH made three observations and his mean position matches UGC 8014.

400/500mm - 18" (5/30/03): fairly faint, fairly large, very elongated ~3:1 NNW-SSE, 2.2'x0.6'. Fairly low surface brightness, but appears irregular or slightly mottled. A mag 14 star is 40" N of center, just off the eastern flank. Located 17' SSE of mag 6.3 SAO 100312.
