Francis Leavenworth discovered NGC 3688 = LM 2-437 in 1886 and noted "lE in PA 0°." His position is an unusually good match with MCG -01-29-024 = PGC 35269, and his position angle is similar. Steinicke lists the discoverer as Ainslie Common, but the closest entry in his list (#17) is a much better match with NGC 3672.

400/500mm - 18" (3/17/07): faint, fairly small, elongated 2:1 SSW-NNE, 0.7'x0.35', low even surface brightness. Located 7.6' SSW of a mag 10.5 star.
