An image of the comet in a post on 7-Feb was substantially distorted because the comet was moving on the star background during registration. An image beneath is "remastered". I took all frames taken during the session (210 individual frames having exposure of 12.34s each) and made averaging by 10 frames (using DeepSkyStacker). As a result, I obtained 21 averaged frames. Then I averaged those frames again in DSS, using comet's position as a reference point.
See the resulted picture beneath [06-Feb-2016 19:01..19:58 EET (UT+2)]:
A size of the image is ~3x3 degree (according to nova.astrometry.net).
[Correction] In fact, only 200 (not 210) frames were used because one of intermediate averaged frames was lost by mistake while final stacking.

According to CometBase.net, a visual magnitude of the comet is ~7..7.5m (visual estimation)
