Francis Leavenworth discovered NGC 1098 = LM 1-67, along with NGC 1091 = I-65 and NGC 1092 = I-66, on 17 Oct 1885. There is nothing at his position but 2 tmin east and 2' north is ESO 546-014 = PGC 10403. Leavenworth noted this was the "1st of 3" [with NGC 1099 and 1100] and this secures the identification. Ormond Stone and Herbert Howe later measured accurate positions (Stone's is given in the IC 1 notes).

400/500mm - 17.5" (11/26/94): fairly faint, fairly small, elongated 3:2 E-W, 1.2'x0.8', small bright core, stellar nucleus with direct vision. Located 5.2' SSW of mag 8.1 SAO 148582! First in HCG 21 with NGC 1099 6.4' SE, NGC 1100 10.1' ESE, NGC 1091 10.2' NE and NGC 1092 11.1' NE.
