You are right about the flicker, there is two problems there. One area of flicker happened for no apparent reason prior to my adjusting the exposure. I had my WB set to sunny day as normal and all other parameters as per normal and I found this flicker; very odd. As the moon set I ramped that in as best as I could to simulate natural darkening. The D4 unfortunately cannot give me complete ramping like a Canon can, but I can live with that. I adjusted the exposure from 10 seconds to 13, then to 15 then 20 and finally 25 seconds over the course of half an hour. The big step from 15-20 seconds (the only option available) present exposure issues. I need to invest in lightroom to do the exposure compensation to remove the flicker. Might look into that this week.

And your lens was wide open? If not, that can be a source of flicker. With 1/2 moon -> no moon, you should be able to keep the same exposure settings throughout and add the ramp in post. Your moon image will start overexposed, but not blown out, so applying a smooth keyframe ramp in post will simulate the natural darkening. I normally do that if the moon is between 35 % and 60%.
GBdeflicker is a good option for reducing flicker if you have one of the video editing packages.
