Being a Nikon shooter, I really liked this shot. ;-)

I am curious about the lens listed. They say it was a 1000mm f 8. I know the Nikon 500mm reflex if an f 8, and they make a 500mm reflex f 5. I also know that Nikon makes a reflex 1000mm f 11.
So, is this a typo, is this a lens I haven't heard of, or did he use a 2X teleconverter and they didn't list that, just the equivalent focal length?
