There are some pretty good images of the AN/PVS-15 Night Vision Binocular at Morovision Night Vision. Seems like there aren't many images of this night vision system out there on the web. It's a very good piece of equipment, if you can afford it, particularly if depth perception is of importance to your objective.

There are some pretty good night vision photos demonstrating the use of a 10x lens with a PVS-14 monocular at: Morovision Night Vision The photos show the differences of using no night vision vs. a 1x lens (typically comes standard with an NVD), vs. 3x Military Magnifier Lens vs. a 1ox Magnifier Lens. The magnification is for real. It looks like it would be a decent piece of equipment to have in your bag, especially if you were doing surveillance.
