Thanks GWAR- I might resort to that. Was it easy to install/figure out?

This is my first attempt at the Milky Way (or any star shots) and I would like to make a Christmas card out of it. This is taken with the DA 12-24 at 19mm, 4500 iso, f4.5, 15 sec. and it is quite noisy. I had to really boost the exposure in post (lightroom 4.2). I see I took 5 shots varying between iso 2200-4500 and f4.5-f5.6 at the same 19mm and same 15 sec. Knowing nothing then (and now!) about darks, flats, bias, etc, all I have is "lights". So my question is: might it be worthwhile to use a program like Deep Sky Stacker (is that what it is called?) and just use the 5 lights? Does it matter that the iso and f-stop varied? I would like to get more into this and this would be my first foray so what would be the best "easy" program to start out? Could I create dark images after the fact that would help?
Also, I took shots of the adjacent part of the milky way with plenty of overlap but CS6 freaks out and won't stitch them. Is there a trick to stitching star shot panos?
Thanks for any suggestions!

You are all encouraging me to get into astrophotography with my K-5 by starting with the 0-GPS1.
I happen to have the Tamron SP400 f4 (65B) which is killer sharp across the frame at f4.5. Would this lens be good for astro work? Does anyone know how the coma and astigmatism is on this lens?
Anything else I should know about using this lens with the 0-GPS1?
Keep posting your photos!
thanks
