Considered to be the best of the globular clusters for northern hemisphere observers, M13 in Hercules, is a large and bright object that provides a good view even in a small telescope. It is one of the showpieces of the northern sky and has probably been studied more than any other globular.
Perhaps not so well known about M13 is that there are a large number of faint galaxies in the same field. The brightest of these is NGC 6207, which is situated about half a degree to the north east of M13. It is visible in the photograph a short distance to the upper left of M13. How many observers have ever looked at this object after looking at M13? At magnitude 12, it should be a very easy object for a 6" telescope.
