The comet C/2017T2 PanSTARRS in that day had a brightness of 9th magnitude and is moving slowly in the Milky Way of eastern Cassiopeia. We can detect an evolved greenish ionized composition and a short dust tail in east direction. The second image captured a rendez-vous field around the Double Cluster and two major nebulae of IC1805 and IC1848. The comet was positioned at about 3.5 degrees NNW from the Double Cluster.
