in the morning sky

 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.
