Thanks, I re-ran it through Dfine2, the Nik noise reduction program and lowered the exposure a half a stop in the brightest area. What do you think? It appears that the last task in Nik should be noise reduction. In the first image I posted I did the noise reduction first, then sharpening, on the theory I didn't want to sharpen my noise, but it appears to work better if one performs noise reduction as the last step.
