John Herschel discovered NGC 4043 = h1055 on 9 Apr 1828 and recorded "S; R; preceds a double star about 30 sec, and is 3' south of it. RA is a rough estimate only from the double star. On the next sweep he logged "Not B; S; R; psbM; 15"." and measured an accurate position.

400/500mm - 17.5" (3/24/90): faint, very small, round, bright core, faint stellar nucleus.
