Lewis Swift discovered NGC 2690 = Sw. III-41 on 10 Mar 1886 with the 16" refractor at the Warner Observatory. His RA is 20 seconds too large. Herbert Howe corrected Swift's sloppy RA around the turn of the 20th century with the 20" refractor at the Chamberlin Observatory and Kobold also measured an accurate position with the 18-inch refractor at Strasbourg in 1897.

400/500mm - 17.5" (2/13/88): fairly faint, small, very elongated ~N-S, weak concentration.
