M57 Ring Nebula

M57 Ring Nebula

This was my second attempt at M57. First time with the new polar mount and alignment. I was happy to increase my subs to 40 seconds, previously I limited to 4 or 5 seconds. I need to remember to take off the reducer next time so the Ring is a little larger in the FOV.
