In my location, there is little time for capturing the comet and accumulating a decent amount of signal. First, I have to wait for it to rise above the wall of the pavilion where the telescope is located, and after that, only about an hour and a half remains until dawn. I didn't risk shooting RGB and limited myself to the L filter.
During processing, I stacked the stars and background galaxies separately, and the comet separately, since it moves quite actively relative to them.
