You've got a nice tail there.

The only way to really do this is to do 2 completely separate stacks for the comet and for the stars, then combine them.  Even then you'll have to do some cleaning up in Photoshop before you combine them.  It's not a procedure for data purists!

A star trail stack from DSS. I prefer this. The gaps in the trail show thin cloud going over.

Same subs etc.
