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.
