Astromania 0.5X Reducer halves the focal length of your telescope, giving you a much wider field of view. You can use this, for example, for doing astrophotography using an astronomy webcam. Using the reducer is ingeniously simple - it is threaded for attaching to a C-Mount standard for C or CS mount CCTV type cameras with telescopes. Screw the Astromania reducer into C or CS mount CCTV type cameras and so double the size of the photographic image field. This lets you take images of much larger areas of the lunar surface, for example. The reducer is also great for taking videos of the Moon using your webcam. You can obtain even larger image fields with your astronomy webcam if you attach an extension tube (e.g. 25mm) between the reducer and camera.Buy at Amazon $37.99
