John Herschel discovered NGC 3536 = h822 on 24 Dec 1827 (sweep 115) and noted "F; S; R; bM; 15 to 20" dia." His declination was 1.2' too small.

400/500mm - 17.5" (4/22/95): very faint, round, 40" diameter, low even surface brightness. The 20' field has only a half dozen stars. NGC 3539 lies 12.3' NNE. Probable member of AGC 1185 and located about 30' SW of the core of the cluster.
