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.
It‘s hard to tell from your image, bit it appears you can even get a bit more details if you register your lights onto the comet itself and then stack all the images. I used Siril for the two step registration process.
But nice image nonetheless!
Thanks! I did try with DSS afterwards to only slightly better results? I’ll give Siril a try too. What do you mean by “register the light to the comet”? Is it a Siril specific setting?
I do not have much experience with DSS, as far as I know the result should be very similar. „Lights“ is the term for a single exposure. The technique is basically the same no matter which software you use.
But if you have Siril specific questions feel free to drop any questions :)
Oh okay, so you mean the light frames. Got it.
Though, I still don’t understand what you mean by “registering the light frames to the comet itself”. I have 140 frames of the comet (albeit not in the same position since I don’t have an astro tripod), and I imported them all into the light frame stack. That’s what I’m supposed to do, or do you mean a more specific step than that?
Thanks again!
