M51 Whirlpool Galaxy

M51 Whirlpool Galaxy
(200 words excerpt, click title or image to see full post)

This image is a combination of files taken two nights ago (8*8 minute light frames at ISO800) and files taken two years ago (10*8 minute light frames at ISO1250), combined in Deep Sky Stacker. I still had some mild guiding issues the other night, so there's a bit of an issue with respect to elongated stars, and the galaxy could be a bit sharper. For a change, I decided to do post-processing on my iPad using the Snapseed application. Came out OK and the app handled my requirements quite well!
