If you need to take photos in low light photos with your SLR camera then the AstroScope 9350 modular night vision system could be your answer. The Astroscope fits between your camera and lense and help intensify low light to give you that perfect picture even on the darkest nights.
At the heart of the 9350 is a CIU (Central Intensifier Unit) that transforms moonlit or starlit scenes into bright, high resolution images that are easily photographed or video recorded. The Astroscopes 9350 is designed to fit a number of SLR and camcorder platforms including Nikon and Canon SLR mounts and has excellent low-light performance and a compact rugged design.
Transform your Nikon or Canon Digital SLR Camera and capture high resolution images at night and in low-light situations otherwise too dark for standard digital cameras. With AstroScope, the light amplification is equivalent to the improvement of 8-10 F-stops so that moonlit or starlit scenes are transformed into bright, high resolution images that are easily photographed.
