Last Friday, I got my new 200-400mm f/4, but because of lots of work and bad weather, I couldn't use it outside. However, this evening the sky was clear and took this shot of the almost full moon from my balcony with the 2x teleconverter.
Including the crop factor of the D300, this picture has been taken at 1200mm.
Watch the picture at full size so you can see the details of its surface. It's been only slightly cropped.
