Lewis Swift discovered NGC 5926 = Sw. I-44 on 15 Jun 1884 and recorded "F; vS; forms a right angle triangle with 2 stars." His position is 30 sec of time too large, but his description is a perfect match. Herbert Howe measured an accurate position with the 20-inch refractor in Denver (repeated in the IC 2 Notes).
400/500mm - 17.5" (7/9/94): fairly faint, small, round, 0.5' diameter, even concentration to a bright core, fairly high surface brightness. A mag 15 star is 1' ESE. Forms a right angle with a mag 9.5 star 2.5' WNW and a mag 12.5 star 2.2' SSW. Located 17' NE of 17 Serpentis (V = 6.3).
