If you have time to answer I would like to ask you how you get both the detail of the stars and the comet so well, in the sense that I tried to stack without a star tracker and with Siril first I follow the stars and the stars are good, then I follow the comet and the comet is good (not so well). Then when it comes to merging the 2 levels I can not do a good job because the trail of the stars is quite similar to the trail of the comet and if I mask the stripes of the stars I also erase the trail of the comet. Thank you.

Well 'thanks and it's not really enough, 2 steps have really opened a world to me:- the first
is definitely this:
In Photoshop I subtract the first image, the one without a star and I get only the stars, completely eliminating the trace of the comet moved. I merge the layers and save the photo.

-the second, which to tell the truth I had guessed and I was trying to achieve with Siril+starnet+bush script, but still without success x various minor problems and with the strong doubt of trying a wrong path because this thing you write is the first time I read it somewhere

I apply StarXterminator to every single image aligned on the comet

Thank you very much, A few lines, but very useful!

Glad it helped.
My processing is the result of various attempts, analyzing the various possibilities of which I had read or seen tutorials and then customize it in order to limit any artifacts as much as possible and also simplify the process. process, however, that takes away a lot of resources to the PC and in the case of StarXterminator applied to over 100 images takes away a few hours of processing, unless you enable the ability to take advantage of the video card's GPU. I
relied on the brute force of the processor, but if you have a CPU not very recent, I recommend fiddling a bit 'to activate GPU acceleration, enormously more efficient.
