How do you "freeze" the stars? I always get horrible results with DSS comet+stars stacking.

I'd also try Sequator for the stacking.
@Bob, love your image, especially @135mm !

Cheers Stefan and JA, I have not stacked images for yrs ,,, my PC died months ago and using a Laptop and only just downloaded DSS on the night of capturing this comet,, I remember back those Yrs ago stacking in comet-mode was sometimes a bit 'Hit and Miss, maybe focal length and/or comet movement.
That said I just loaded the images straight in to just see what it would produce, and DSS spat out exactly what is you see with Stars and comet aligned.
