Description

So this is my first comet ever. I did not know what to do, but i got a hint from AB's forum (thanks again, Andrea Alessandrelli), so after finishing my M 27 lights i entered the actual coordinates for 21P from theskylive.com and saw the comet. I took a few photos and did my best to process them. Now i am entangled to comets and will try this again, with a different setup (more focal length) and different processing.

This picture was taken while 21P was 110 million kilometers away and had a magnitude of 13.9.

Note to mysself: Calibrated with SiriL (can do this with DSS also), stacked with AS! and processed with PI.
