Comments:
Moon was a bit of a factor. It was waning gibbous and still pretty near full. Shot the blue images first then luminance then green then red. Thus the moon was low when the blue images were shot and higher when the red images were shot. I think this minimized the effect of the blue atmospheric light generated by the moon... Need to shoot this again when moon is new.
