I collected data on C/2017 T2 (PANSTARRS) recently, but have not been able to process it successfully. This is because the comet is moving so slowly that when integrating the stars don't train enough for them to be eliminated by pixel rejection during integration. (method I tried to use as per Warren Keller's book).
Here is a link to the calibrated subs if anyone wants to have a go:
