William Herschel discovered NGC 6324 = H III-945 on 12 Dec 1797 (sweep 1071) and logged "vF, S, E. I saw it also with 320x. A small star is south of it; a 2nd is preceding and a 3rd following." His description is a perfect match with UGC 10725. Bigourdan measured an accurate position on 22 Jul 1884 (repeated in the IC 2 notes).

400/500mm - 17.5" (5/14/88): fairly faint, very small, slightly elongated, diffuse, small brighter core.
