Comet Catalina US10
in the morning sky
January 12, 2016

 This is the first light image set for our new Orion 10" f/3.6 astrograph. I dont have the CCD up and runnnig with it yet, however this shot with the Hutech Modified Canon XTi shows much promise and the subs have pinpoint stars right to the very edges.

The comets dust tail is now very dominant in this image, seen here as a broad dust fan pointing downwards with a sharp left edge. The gas tail is the blue streamer pointing to the right.
