Comet C/2013 X1 (PANSTARRS) imaged on June 12 2016, only 10 days before its maximum approach to Earth with a brightness near magnitude 6.5 is observable through binoculars.

In this wide field image highlights a greenish coma with an appearent diameter as big as the Moon, from its departs toward upper left a dust trail (type III) with more than a degree long, also can be viewed a long and narrow ionic tail very faint towards right. As novelty aso can be observed the begin of its classical dust tail (type II) projected only a few arcminutes towards upper right.

The brishtest star of the field is Iota Piscis Austrini with magnitude 4, and also can be perceived near the down right corner a small and faint interstellar cloud associated to infrared emission source IRAS F21276-3327.
