M57 Ring Nebula

Here's this years attempt at the Ring Nebula. I finally found the program to help get the polar alignment nailed down. "Alignmaster" does the trick and is easy to use. After about 5 minutes, the mount was ready to go. The autoguider only has to make minimal adjustments and I was able to get nice round stars. Took 40 minutes of data (40-1 minute images) captured with Nebulosity and minimum final processing in PS elements.
