M13 is perhaps the most famous globular cluster in the Northern Hemisphere. It is usually one of the first deep space objects a new amateur will try to center in his telescope, and for good reason, it is truly a spectacular sight even in small telescopes. The cluster is estimated to contain over 300 thousand stars. These stars orbit each other wildly in a ball of approximately 145 light years in diameter. This globular is composed of some of the oldest stars in the Universe. The age of these stars is estimated to be over 11 billion years. The cluster is located about 22,000 light-years from the earth in the direction of the constellation Hercules.
