M13 appeared as a large, bright and round ball of light at 49X with good
resolution around the edges, espescially on the S and SW side of the cluster.
At higher powers M13 is a blazing ball of light fully resolved into stars
right across the core, with a bright background of light from unresolved
fainter stars. 
The stars of this cluster appear to form spider-like arms. Also M13 is not
exactly round and there seemed to be a sharp edge on the North side. 
This is one of the best globulars that I have so far seen.
