Description

This is the second time I've attempted this target; it was the subject of my first ever astrophoto two years ago as well. You can definitely see the improvement but I think I could do this image so much better than it came out. I was trying some new techniques for shooting and ended up having a lot of problems that I now think I could fix. I really want to have one more go at this area soon.
