Baade's Window NGC6522 & NGC6528 Globular Clusters near the center of the Milky Way Baade's Window 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 (center) in Sagittarius. The bright star south of NGG6528 is Alnasl or Gamma Sgr (10 Sgr) magnitude 2.98.

Center of the Milkyway labeled

This Takahashi Epsilon 180 f/2.8 image with a Canon 20da camera is aimed at the center of the Milky Way.

The image has been labeled to show some of the open clusters and regions of nebulosity near the center of the Milky.  The actual center is hidden from optical view by gas and dust.
