Baade's Window	NGC6522 & NGC6528	Globular Clusters near the center of the Milky Way		Walter Baade was unable to observe the Galactic center itself due to obscuring dust, but he found regions of less obscuration close to the heart of the Milky Way, including “Baade’s window,” which is centered around NGC 6528 (left) and NGC 6522 (right) in Sagittarius. The bright star off the frame south of NGG6528 is Gamma Sgr (10 Sgr) magnitude 3.63.
