Description

I saw that the comet was passing close by to open cluster NGC1647 so I had to give it a go.
This was my first attempt at a comet using a mono camera and RGB filters. SXT and PI comet alignment make it a lot easier than it used to be, but I ended up with so many files I kept having go back and try again as I kept using the wrong ones! The only other issue was v. faint residual star trails left behind by SXT. You don't notice them in individual frames but end up with faint streaks when stacked.
Pleased with the final result though.

Description: Combined the comet and the stars with a different PixelMath expression (max instead of screen). Gives a smoother result, at the expense of some fainter stars.
