Messier 13

Messier 13 (M13, NGC 6205), also called the 'Great globular cluster in Hercules', is one of the most prominent and best known globulars of the Northern celestial hemisphere. It is more than 25,000 light years away. It is composed of hundreds of thousands of stars. Above the cluster, near the top of the frame is the Galaxy NGC 6207. While it appears close to M13, the Galaxy is million of light years behind the cluster. This image is a 90 minute exposure, with 30 minute exposures through red, green and blue filters. The image was taken on May 15, 2009 with a Takahashi FSQ 106 refractor and an SBIG STL11000 CCD camera. Click on the image for a magnified view.
