Description

This is a complete redo of my previous M51 with my planned 90 degree CCW crop for my preferred view. My goal was to focus on detail and Ha. I used SubframeSelector to rank my calibrated 570 sixty second lums and wound up tossing 305 leaving the best 265. I then used the the un-calibrated versions and ran WBPP with all 481 subs.

This time I did not have to worry about the Zwicky Galaxy Cluster and could concentrate on just M51 and it's companion. I tried to make the image okay to view at full resolution and used a different process to add the Ha which brought out more.
