Nikon F-mount to P8079HP Adapter

I made this adapter flange to couple surplus imagine intensifier tubes with Nikon F-mount lenses. It works great on the P8079hp intensifier I used. Old Nikon glass can be had at fair prices on ebay, and the rear objective covers much more of the sensor than the more commonly used CS lenses, and vintage C-mount lenses. It has a passage cut to install the ground wire, and can be held on by a rear mount flange. Old cascade tubes can be had fairly cheaply 60-130$ military surplus, so if you have one lying around but don't have the original optics, but have or manage to find an old piece of Nikon glass with a low f rating preferably f<2, you can slap it onto the tube use it instead.
