M57 23rd July 2004Home

This is my second attempt at M57, the Ring Nebula.   It was imaged with my LX200 starting at 23:40 UT on 23rd July 2004.  I captured 78 frames exposing each for 30 seconds with a modified Vesta camera.  However my tracking is not as good as it might be, so I had to reject most of the frames due to trailing of the images.  This is a summation of the best 12 frames.
