Description

M13 is a magnificent globular star cluster with perhaps as many as one million stars. M13 is rated at magnitude 5.8, and is located in the constellation Hercules. Hercules is relatively close to the Virgo cluster of galaxies. Consequently, a magnitude 11.4 spiral galaxy known as NGC 6207 is located so close to M13 from our line of sight (28 arc-minutes to the northeast) that it can often be seen in the same telescopic field of view. M13 is not only a splendid globular star cluster, but it also offers the bonus of a spiral galaxy nearby when viewed through a telescope. However, M13 and the galaxy only appear close together because they are both on the same line of sight viewed from Earth. M13 is about 25,000 light-years away. NGC 6207 is located millions of light-years away.
