NGC 6522
17.5" (7/11/99): this globular is the larger and brighter of a fairly faint pair with NGC 6528 in the same field just 16' E. At 220x the halo is ~2' diameter with a very small bright core. A mag 12.5-13 star is embedded in the NE side. At 280x, the 25" core appears offset east of center and the halo is slightly elongated E-W. Passing through the core is apparently an unresolved string or bar of stars oriented WNW-ENE (just slightly fainter than the core). The globular is lively but without resolution. With averted vision the outer haze increases in size to ~3'.
13" (6/29/84): moderately bright, mottled. A single brighter 13th mag star is on the ENE side. This is the larger and brighter of a pair with globular NGC 6528 15' E in Baade's Window.
