M13, October 23rd

The Hercules Globular Cluster has long been one of my favorite objects ever since I viewed it through my 10" Dobsonian. Visually it takes your breath away and it's a rare object that almost looks better "live" in the scope.

 

Alignment and tracking is improved. Slight issues with focus and the field flattener distance was incorrect. Most of that is cropped out here.
