M13 (NGC6205), in the summer constellation Hercules, is the largest globular cluster in the northern emisphere. M13 is apparently extended over a diameter of 23'. This type of cluster was formed in the first part of the galaxy life, during the contraction of gases and dust to form the billions of stars which are contained into the galaxy border. Modern estimates give over a billion stars which forms the cluster. The look of this object through a scope is simply amazing, and many are hooked from this vision. A high resolution picture of M13 require steady conditions to resolve many of the stars.
