Lewis Swift discovered NGC 800 = Sw. II-17 (along with NGC 799 = Sw. II-16) on 9 Oct 1885 with the 16" refractor at Warner Observatory. His RA is 30 seconds east of UGC 1526 = PGC 7740 (same error as NGC 800). Herbert Howe measured an accurate position in 1897 using the 20" refractor at Chamberlin Observatory (repeated in the IC 2 notes).

400/500mm - 17.5" (12/8/90): extremely faint, very small, round, very low even surface brightness. Forms a close pair with NGC 799 1.8' N.
