About this image

Messier 13, in the constellation Hercules, is a globular cluster of hundreds of thousands of stars.  It is a spectacular sight in moderate sized telescopes, looking rather like diamonds sprinkled on black velvet. The cluster is about 24,000 light years from earth and approximately 145 light years in diameter.

Peter took this image during a full moon.
