C/2013US10 (Catalina) in Camelopardalis

There was evidence of a good seeing last evening however weather had turned bad quickly. Nevertheless, I managed to take an "express" picture of the comet during a short period of clear sky.

The picture was taken using Canon EOS 600D (on a tripod) with EF50mm f/1.8 lens.
This is an average of 10 frames (3s each); f/2.5; ISO=3200. Frames were processed using DeepSkyStacker, then with FITStacker (resulted image) and finally with RawTherapee. Date/time: 30-Jan-2016 ~20:07 EET (UT+2). Place: Kyiv (Osokorky).

Zoomed part of comet's vicinity. There is a visible coma of about 5' in diameter (size of the image is 1.18 x 1.18 degrees -- by Astrometry.net)
