Messier 51 over two years

The image you are seeing right now is a little bit over 20 hours of exposition, over two years. Every single image was taken in my backyard, under an average sky and a bortle 7. Because the sky was not that good, I had to trash a lot of images and shoot under the rare moonless nights. Since I started about 3 years ago, this image is one of the biggest projects and accomplishments I have ever done in astrophotography.
