Comet Catalina US10
in the morning sky
December 6, 2015

 
 This
            comet is now very easy in the binoculars once it clears the horizon
            haze around 5:30am. Now over 15 degrees in altitude, the comets
            tail is starting to show more length and structure. The bright
            crescent moon was lighting up the eastern sky here, but its glow
            was subtracted out in processing. The gas (ion) tail points to
            the upper left here, and the dust component to the lower right.
