M57, the Ring Nebula Again

A definite improvement over my 2006 attempt. This is the center crop of the full frame. The DSLR @ f/6.3 may not be the best camera for this small object; some day I'll try the DMK @ f/10 on it--if I can keep my guiding running smoothly enough.

30 x 240 sec, 10" LX200 @ f/6.3, 350D @ ISO 800, Astronomik CLS, guided with ST80/DSI/PHD Guiding
