Uploaded 12/07/20

 
This
            comet is approaching the center of Auriga and will make stunning
            pairings with many deep sky objects in the coming weeks. Currently
            around 8th magnitude, this small comet has faded considerably
            in the past month and shrunk in size. This is a 1 hour exposure
            with the 10 inch f/3.9 and new ZWO CMOS camera.
