Francis Leavenworth discovered NGC 303 = LM 1-20 in 1886 with the 26" refractor at the Leander McCormick Observatory. His position is 1' N of PGC 03240. Herbert Howe measured an accurate position in 1898-99 using the 20" refractor at Chamberlin Observatory (repeated in the IC 2 notes) and he noted the PA was 160°.
400/500mm - 17.5" (10/21/95): extremely faint, very small, round, 20" diameter, low surface brightness with just a weak concentration. Can almost hold steadily with averted vision once identified on my finder chart.
