D800 runs rings around a planet

Focal length of 2000mm is enough to resolve the ring around Saturn. Not the best image I ever made (normally I use high speed video for planets averaging out atmospheric turbulence, and working with monochrome CCD and filters), but I had some film left in the camera and I thought Saturn was a good model
