Globular Cluster in Hercules
The constellation Hercules contains two impressive globular clusters. One of these is the famous Messier 13. The other, Messier 92, is also a very fine target, and it is not very difficult to locate. It is roughly the same distance from Earth as Messier 13, but it is somewhat smaller and less impressive. However, the stars in its periphery are fairly easy to resolve, and as can be seen in this image, it has a very bright, dense core.
