Nikon 400mm f/2.8 for Astrophotography

I exposed the Moon using my Nikon 400mm f/2.8 AI-S manual focus lens last night. The seeing was not great, there was a lot of haze and fog near the horizon as well as heavy dew rapidly forming when I took this shot. The atmosphere was not that stable, there was a high level of star twinkling indicating atmospheric instability. That did not seem to matter as can be seen in this shot. Nikon D300, 1/20s, f/16, Nikon TC14E-II 1.4x teleconverter, ISO 400 mounted on a standard tripod from Really Right Stuff. The effective focal length: 400mm x 1.4 x 1.52 = 851mm.  Damn, I’m sure really loving this lens!!!!!

For an idea of how much dust and pollen haze was present here is a shot taken at sunset, note the deep dark orange all along the horizon. This shot was a completely untouched jpeg, strait from my D3s:
