I shot this two nights ago and in post, I am getting some very nasty mottling and banding in the sky. Particularly bad in sRGB @ JPEG quality of 60 (my usual) and noticeably, but not acceptably improved in AdobeRGB/100 quality. I did push the HSL sliders around in LR, but fairly modestly (nothing over 25). What you see is even with Topaz denoise at 0.5, which is high in my experience, and a 10 pixel Gaussian blur masked into the sky! I've gotta be missing something. I like the complementarity of the colors. Any help, much appreciated.
