Wilhelm Tempel discovered NGC 4766, along with NGC 4757, in 1882. In the narrative portion of his fifth paper (AN 2439) he mentions finding two nebulae about 10' north of Winnecke's GC 5674 [NGC 4760]. Although no positions were stated, they were probably measured and communicated later to Dreyer, as the NGC position is 20 seconds of RA west of MCG -02-33-042 = PGC 43766. This galaxy lies 7' due north of[NGC 4760.

400/500mm - 17.5" (5/17/90): faint, very small, slightly elongated NW-SE, small bright core. A mag 12 star is 1.0' ENE. Forms a close pair with an anonymous galaxy 1' NW.
