Last image I took of comet C/2017 O1 (ASASSN) on December 17th 2017, when was definitely going away from inner Solar System and its brightness had dropped to magnitude 11.5. The comet still was showing in those time a small tail on a field of interstellar clouds at only 4º from celestial north pole.
