Interesting! I also tried CCDStack and I couldn't get a good result. Then I tried making an inverted blured/smoothed object mask in CS5 and subtracting. This initially looked ok, but the sky values were too clipped and brightening just revealed left over non flat background. But, one click in the exterminator plugin gave a pretty fantastic result! It comes with a free trial so go for it. Curious how it might work for you!
