The skies cleared for awhile at sunset so I setup the scope and photographed M57 at prime focus of my Celestron Edge HD 9.25" SCT. This was my first attempt to take guided photos at prime focus. Once I got the polar alignment set, I pointed to M57, chose a guide star and took a series of 30, 60, 90 and 180 second exposures. Here is the best picture I ended up with consisting of the following:
14 Subs of 60 seconds each
Canon modified XSi at 1600 ISO
PHD guiding software, BYE capture
The evening was ended about 10:30pm when high clouds moved in making guiding very difficult.
