M13 Globular Cluster in Hercules

This is the great globular in Hercules. One of the first awe inspiring celestial objects I ever looked at through a visual telescope. This is my third time imaging this target and my goal was to go deep and to bring out as many stars as possible without blowing out the core. Captured over 30 hours of integration time from my ROR observatory in my backyard. Also available on Astrobin here.
