Stephane Javelle discovered IC 146 = J. 1-70 on 30 Sep 1892. His position matches ESO 543-006 = PGC 6083. This galaxy was probably discovered earlier by Leavenworth at the Leander McCormick Observatory in 1886. Leavenworth's rough position for J. 1-70 (later IC 146) is 1.6 min of RA east of this galaxy, a typical error. Because of the poor position, Bigourdan was unable to recover the galaxy and Javelle assume his observation was new. Herbert Howe reobserved and measured an accurate position for NGC 648 around 1900 (repeated in the IC 2 notes), though neither Howe nor Dreyer noticed the equivalence NGC 648 = IC 146. ESO states the equivalence NGC 648 = IC 146. See Corwin's notes.

400/500mm - 17.5" (12/4/93): faint, slightly elongated, 0.8'x0.6', weak concentration. A bright uneven double star h2067 = 7.6/11.6 at 34" lies 10' ENE.
