ATN produces a Gen 4 nightvision scope with an adapter for SLR's, though inconveniently sized. Macro lenses are advised for direct photography of the photoelectric screen of the nightvision scope. My understanding is that a Gen 4 scope has superb resolution and may actually be adaptable to night digital photography. Anyone with experience? Some postings of sample photos would be interesting stuff. Pricey units though, those Gen 4's.
