Comet C/2013 US10 (Catalina) last night (07-Feb 2016) between 19:29 and 19:59 (UT+2).
Unlike early observations (when the comet had two tails: 29 Dec; 8 Dec) only one curved dust tail is seen now. It is considerably shorter and weaker than before because of a bigger distance between the comet and the Sun.
Setup: Canon 600D + EF 50mm f/1.8 II on fixed tripod.
Shooting options: 110x12s; f/2.5; ISO 800.
Processing: DSS+FITStacker.
A size of the cropped image is ~3x3 degrees.
Comet's tail is better seen in the black-and-white image with increased contrast:
The image beneath covers area of ~6x6 degrees:
