Description

I've been chasing the supernova in m101 for an amazingly stretch of clear skies here at home. Then the Canadian smoke came along with normal weather. So I thought I'd stack almost the 17 hours of subs. Processing using WBPP took 11 hours of computer time. Crunch crunch crunch. I also drizzled x2 since  the image would be on the small side using the Redcat71.
