For ultra high quality long distance imaging, I use my Nikon SLR along with the gun sight mounted to the tripod as shown in Figure 18. This system allows the acquisition of images with ultra high details from a distance of a block away when using the camera at full quality resolution. There is only a slight darkening around the edges of the image, but other than that the quality is very good considering how easy to build and inexpensive this setup was.

To test my gun sight version of the zoom extender, I set the camera for no flash, quick exposure and then shot a scene over 500 feet away on a dreary snowy day. The image was bright, crisp and full of detail as shown in Figure 19. The license plate was huge when I viewed the image on the computer screen with no scaling. I could have probably seen the color of a person's eyes at this distance using the zoom extender. The crosshairs were a bit annoying, so I later removed them from the gun sight.
