M57, First Light with QHY163C

24x120 second subframes,

Total exposure 48 minutes.

 

Quite a lot of high level cloud, light wind and not great seeing. My FWHM values are quite a lot worse than the comparable image with the 350D. But still, it's a first light picture!

 

Quite a learning curve going from the DSLR to the dedicated Astro camera. Quite glad I went OSC before Mono...
