William Herschel discovered NGC 718 = H II-270 = h164 on 13 Dec 1784 (sweep 338) and logged "pB, S, iR, mbM". John Herschel made two observations and called it "B; R; psbM; 25" [diameter]" (sweep 300 on 25 Sep 1830).

200/250mm - 8" (10/13/81): faint, very small, round, bright core.

400/500mm - 17.5" (11/6/93): moderately bright, fairly small, round, increases to very small prominent core, stellar nucleus, very faint larger halo 1.5' diameter.
