This image was created by median combining 7 x 90 second unfiltered images taken with a Takahashi Epsilon 250 with SBIG ST-8XE CCD. The image has been cut down to be 20 x 20 arc minutes in size.

Messier 9 (NGC 6333) was discovered by Charles Messier in 1764. It is one of the nearer globular clusters but is still significantly dimmed by interstellar dust, especially to the north and west.
