Description

This wonderful galaxy is so popular, but I wanted to give it a try during galaxy season. Nevertheless, processing M 101 was fun, but a real challenge at the same time!!! Though I captured more than 4 hours H-Alpha, I finally decided not to let the Ha data pop up too much in the picture to get a more natural look. In this wider field, the neighbors NGC 5474 & 5477 join the pinwheel. Hope you like it!
