Francis Leavenworth discovered NGC 1650 = LM 1-137 on 12 Nov 1885 with the 26" refractor at the Leander McCormick Observatory and noted "mag 13.0, pS, E 0? [N-S], glsmbMN, envelope mag 14.0." His position is 3.6' SW of MCG -03-13-001 = PGC 15931and the description pins down the identification. Herbert Howe measured an accurate position in 1898-99 using the 20" refractor at Chamberlin Observatory (repeated in the IC 2 notes).

400/500mm - 17.5" (12/23/89): faint, very small, slightly elongated, bright core. Located 11' E of a mag 10 star at the edge of the 220x field.
