Ormond Stone discovered NGC 1780 = LM 1-145 in 1886 with the 26" refractor at the Leander McCormick Observatory. His rough position (nearest min of RA) is 1.6 min of RA west and 1' north of ESO 553-001. 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" (1/20/90): very faint, very small, round. A mag 13 star is 1.4' NNE.
