Comment :

In a later attempt I processed the image in Siril and Gimp and flatten out the background. Maybe easier to see the comet then.

I have now learned more about the comet, when they first found it it had the name P/2010 V1. After that it broke apart in several fragment. It's a 5 year periodic comet and it came back 2015 when this photo is taken. But now as many smaller fragment. It has a new name 332P/2016 Y2, each fragment has an index, A, B, C ... When looking in the high resolution image above I can see an object that are a bit elongated, could it be the comet, I have made a mark on it. Most of the fragments you need a Hubble telescope to see them.
