Unfortunately the comet is so faint on a single image that DSS fails to select the comet, so I tried my luck with PI.
Since hours I'm trying to process it with help of various tutorials... with no really good result.
I'll continue to process it with various methods. Still hope for a better result ;-)

Edit Image B: complete re-processed with another reference point for the comet and "comet-only image" subtraction from the "stars-only image", which I had not done before...
Much better result :-) I'm happy!
