M13 - the Hercules Cluster

This is another one from last Saturday night. The Hercules Cluster, located in the constellation Hercules of course, lies about 25,000 light years away and contains hundreds of thousands of stars. The image scale is obviously way too small for my William Optics Zenithstar 80FD at 444mm focal length (with the flattener/reducer).
Below is a close-up crop of the full-frame image. I didn't get a lot of detail but I think it's OK for my first try:

Here's the full-frame version. You can see how small M13 is in this image.
