Once you've done this make a masking layer and selecting the brush tool, set the hardness to like 30% and slowly blend the two images together. I've personally struggled with getting proper panoramas even in CS5 simply because of vignetting and creates uneven gradients in the final image where you blend.
Good luck!

No stars in a solar image. I have the frames perfectly aligned though...it's the join marks that are my problem...and yes the brightness is ridiculous in how much it varies given the imaging camera setting never changed through the session
I'll try your technique and see if it helps. Thanks
