Here is a stack of 11 images of M57 - six are 5-minute exposures, and five are 15-minute exposures. I summed the exposures so as to not have to worry about the different exposure lengths. This doesn't quite show all of the outer shells; there are some dim ones even further out than this.
Another nice side effect was a lot more detail on the galaxy IC1296 to the upper right. A few more distant galaxies can also be seen. I used two layers for this image, one with just M57 in it and the other with the background. Stars got kind of bloated with the extreme stretch required to show the outer shells, so I used Photoshop's Minimum filter to trim them down to size.
Taken with the C14/ST-10XME/Paramount ME remote setup in New Mexico.
