Wow! That looks incredible. Great job!!
That is the best I have seen with that lens. What is your secret!!
Here's another Supermoon image with the D7000 and the 80-400VR.
That's very easy. Do this:
Use spot metering
Use the lowest ISO you can
Crop the final image to 100%
Apply some sharpening
You don't need a tripod for this neither a fancy lens. But the higher the resolution the better.
