A company called Electrophysics has two adapters that can make your Canon or Nikon dSLR snap pictures in the dark. Such an application isn't new and was previously implemented in surveillance and video cameras for recording footage in the dark. But the AstroScope 9350-series adapters are specially designed to be used with dSLRs.
These night vision systems fit between the camera body and the lens. There is a central intensifier unit (CIU), which illuminates the scene dramatically even if there is only a weak light source. What's special is that these adapters maintain the electrical connections required for image stabilizer operation and autofocus by the optics.
Electrophysics did not announce the pricing and availability of the AstroScope on its Web site, but we don't think such a niche product will sell cheap.
