Francis Leavenworth discovered NGC 858 = LM 2-328 in 1886 with the 26" refractor at Leander McCormick Observatory. His position is 0.7 min of RA east and 1.7' south of ESO 478-013 = PGC 8451. Herbert Howe measured an accurate position in 1899-00 using the 20" refractor at Chamberlin Observatory (repeated in the IC 2 notes).

400/500mm - 17.5" (10/29/94): extremely faint, moderately large, round, 1.2' diameter, very low surface brightness. Weak concentration at the center. Located 8.5' W of a mag 10 star. A faint companion off the east side was not seen.
