NGC 6528
17.5" (7/11/99): this is the smaller and fainter of an unusual double pair of globulars with NGC 6522 just 16' W. At 220x, it appears round, ~1.5' in diameter. The brightness gradually increasing towards the center but with no distinct core. The surface brightness is fairly smooth overall and the outer halo is fairly well defined. A mag 13.5 field star is at the SW edge. The surrounding field is noticeably more vacant than around NGC 6522. Both clusters can be placed at the edges of the 14' field of the 7mm Pentax XL. Situated within "Baade's Window" (absorption hole in the Milky Way).
13" (6/29/84): fairly faint, small, 2' diameter, not resolved. This is a smaller and fainter version of globular cluster NGC 6522 15' W.
8" (6/19/82): fairly faint, small, easily visible but no resolution.
