M13 is one of the best known globular star clusters in the sky, and probably the best known in the northern sky. What isn't as well known is the fact that there are hundreds of tiny galaxies in its immediate vicinity. These galaxies aren't actually close to the cluster but they appear in the same field of view from our perspective.
