The Pinwheel Galaxy M101 in Ursa Major.

I revisited the Pinwheel Galaxy M101 in Ursa Major on April 16, 2023. I shot this same galaxy about this time last year but wasn’t able to get the time I wanted on the object. The Pinwheel is about 21 million light years away from our Milky Way Galaxy. I processed 112 two minute subs (almost 3 hours and 45 minutes of exposure) on this galaxy. I cropped down this image in order to highlight the galaxy.
