Dave, That's a nice photo. It's always best to use the longest lens and the lowest ISO you can get away with when shooting the moon, especially when using a DX camera. A full moon will always have the least detail because of the lack of shadows. You'll need to increase the sharpening.
Here's a photo I took a week ago before the full moon.
I use the D800, AFS 70-200mm f2.8 VR II plus the TC_20E III. ISO 400, 1/320, f8.
