    I'm currently saving up to get started with astrophotography so I figured I might as well get as much practice as I can until that happens. I downloaded GIMP today and this is my first attempt at processing an image. Well, kind of my first attempt. This image is actually my third try today working on the same one. I know there is an issue on the left side, but this is the best I could do. Working with this was very fun and has me even more excited to get started with my own.

    All processing was done in GIMP.
