Something I do is, if you have a large image 4kx2k pixels.
measure the x/y location of the comet in each image. no need to align them first. Then crop the same size area around each x/y location, 1000x500 pixels, with an offset to put the comet at about 750x 250y. Your comet will now be with a few pixels in each frame. Do the align process to lock it in.
A good medium or sum will be easier. Ask me if you don't get it...??

kind regards, Alan
