William Herschel discovered NGC 4704 = H II-662 = h1439 on 9 Apr 1787 (sweep 725) and recorded "F, S, R, bM." JH made two additional observations.
400/500mm - 18" (3/30/05): faint, fairly small, round, fairly low surface brightness with only a very slightly brighter core which seems offset from the geometric center. Located 6.4' SE of mag 8.6 SAO 44330 and 54' NW of M94.
