Description

This was a quick 10 minute edit in Photoshop after stacking in DSS. I was at a rental over the weekend near Cloudersport and Austin PA doing some astro. I can't believe how dewy it was there.

Updated it with better processing methods, but man my stars were bad.

Description: Since it is raining I figured I'd go back and hit old data with new processing things I've learned. I am going to go after this one again with the scope carefully collimated and better guiding along with good calibration frames.
