A good comet/stars composit tutorial?

[Vega]

Dear budding astro-imagers!  Please Help!

I have two stacked images of Comet 41P. One stacked on the stars, the other stacked on the comet. As most people know, stacking on the stars causes the comet to become elongated and stacking on the comet causes streaky stars and the solution is a composite. Does anyone know of a good step-by-step tutorial on how to do it? Preferably in Photoshop (I don't really like the DSS solution).

What methods have others found successful?

Any help greatly appreciated

You can stack in DSS using both so neither are streaky or elongated which given this comet is not tail abundant I think will suit it.

When lovejoy was around I think some did two stacks with alternate options then extracted one to use as a layer into the other in a photo editor.
