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 5 (NGC 5904) was first seen by Kirch in May 1702 and Charles Messier found it independently in May 1764. He described it as a round nebula which "doesn't contain any stars". M5 is thought to be one of the oldest globular clusters - 13 billion years - and one of the largest with a diameter of 165 light years.
