Maintains the same back-focus as when used at f/10: Unlike generic reducers the EdgeHD.Design: 5-element optical layout designed specifically for the EdgeHD 11" to maintain the flat-field performance of the EdgeHD optical design. ![]() 7x reducer, your telescope becomes the most complete imaging system available in its price range today. With the Fastar option on all EdgeHD optical systems, coupled with the. Incorporating computer assisted CNC machined aluminum housing, for precise spacing and alignment of optical elements, and threaded metal covers on the lens assembly to protect your investment from dust and scratches, our reducers offer you an outstanding mechanical design. Large diameter lens elements, up to 60mm clear aperture, ensure that the optimized image circle remains at a generous 42mm for use with large CCD sensors. All air to glass lens surfaces feature multiple layers of coating for maximum light transmission and color correction and contain blacken edges to minimize internal reflection and maximize image contrast. Unlike generic reducers, our premium reducers provide substantial back-focus to accommodate an assortment of imaging accessories.ĮdgeHD reducers offer high-index optical elements, including extra-low dispersion, exotic Lanthanum elements, which provide high contrast viewing while minimizing chromatic aberration. Celestron’s EdgeHD reducers feature a custom 5 element optical design engineered to maintain the flat-field performance of our award-winning EdgeHD optical system. ![]()
