John Herschel discovered NGC 4652 = h1413 on 1 May 1831 and recorded "Not vF, pL, gbM. It is almost 6' dist np two stars sts 8 and 10m". His position is 15 sec of RA preceding CGCG 293-035 = PGC 42802, but the two bright stars are just where he placed them southeast. Interestingly, Dreyer insisted the two stars were northwest, while observing at Birr Castle on 27 Apr 1875.

400/500mm - 18" (5/12/07): very faint, elongated 5:2 SW-NE, 0.8'x0.3', very weak concentration. Located 5'-6' NNW of a wide pair of mag 7.9 (HD 110762) and 9.6 (HD 238153) stars.
