Reprocessed M51

Thanks to Ken, who showed me how to make an object mask in Photoshop!  This is reprocessed version of the image posted in my last update. Amazing what a little tweaking will do!


Here's a version with higher contrast, but with less detail more artifacts. I ran it through Astrometry. net and, as you can see, two fainter galaxies ICs 4277 and 4278 (magnitudes 15.4 and 15.7 respectively) are lurking in the background.
