2017t2 20191006 rroberto

At 02h40 UT (approximately) October 6th I observed comet C/2017T2 with the Cassegrain telescope of Frasso Sabino (diameter 369mm focal 2464mm i.e. F/6.66). They are the median/sum of 24x90sec with north on the top and east on the left. Scale 1".34/pixel and field of 22'.5x28'.2. I scaled the image in a logartmic way.

The magnitude using a diameter of the circle of 30 pixels (about 40") is 11.6 and you see a tail of 4'.8 in PA 236.
