NGC 6522, NGC 6528, & Baade's Window
This fascinating pair of globular clusters lie together just beyond the
spout of the Sagittarius teapot, and from our earthly vantage point they are
separated by only 16 arcminutes. They are seen through the very dense
starfield of the Milky Way, although NGC 6528 (right) is on the border of a
dark nebula called Baade's Window.
This image was taken at the Mount Lemmon Sky Center, under the

The full resolution image is available
here, but be
aware that it is very large and may take some time to load.
