For my first attempt at using PI I chose to process an image of M51, the Whirlpool Galaxy which I took back on April 20th. It's taken me all week but I'm excited to release the final product! I may have gone a little overboard with the saturation but I was so excited to be able to adjust it without bringing more noise out that I couldn't help myself :)
