We got extremely lucky and got a tiny window of cloudless sky in an never ending sequence of cloudy nights. Also the conditions were a nightmare with severe light pollution and lights shining directly at our equipment.

And maybe somebody here can explain to us what the ionized gas is that 'shoots out‘ in front of the comet?
Also do the colours seem to be correct? We tried our best at background extraction and maintaining the true colour, but the raw data was of poor quality. From images of other comets the dust tails normally seems to have a yellow/orange colour and only the plasma tail is blue.
Edit: found the answer to the Anti-tail. It shows the trail of dust were the comet has traveled, which appears to come out at the opposing side because of earths angle relative to the comet and sun.
The comet is also visible on one single exposure as it is very bright. It was also visible to the naked eye. But stacking reveals even more details because it improves the signal to noise ratio. Also stacking helps removing unwanted objects like satellite trails, planes or moving clouds.
I see. Thanks for the answer!
