Comet C/2013 US10 (Catalina) imaged on January 13th 2016 in a wide field. Its long ionic tail is projected toward west to a distance of more than 6 degrees, but more faint and with less details that in my previous image taken only two days ago; however the dust tail more short and brilliant toward south barely changed. Aside from several small galaxies scattered by field, in the upper right highlights the classical spiral galaxy M 51: the Whirlpool Galaxy.
