About this item

  • 2-Year Warranty
  • The EdgeHD .7x Focal Reducer Lens makes your EdgeHD 9.25" one full F-Stop faster than f/10, reducing your exposure time by half to capture the same brightness of object
  • 4-element lens design
  • Maintains similar flat-field performance as native Edge HD optical design
  • Increases Field of View by 43% to Better Capture Wide Field Images


Celestron's new EdgeHD reducers features a custom 4 element optical design engineered to maintain the flat-field performance of our award winning EdgeHD optical system. Unlike generic reducers, our premium reducers provide substantial back focus to accommodate an assortment of imaging accessories. EdgeHD reducers offer high index optical elements, including extra low dispersion, exotic Lanthanum elements, which provide high contrast viewing while minimizing chromatic aberration. 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. 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. With the Fastar option on all EdgeHD optical systems, coupled with the .7x reducer, your telescope becomes the most complete imaging system available in its price range today Performance Design: 4-element optical layout designed specifically for the EdgeHD 9.25" to maintain the flat-field performance of the Edge HD optical design Maintains the same back focus as when used at f/10: Unlike generic reducers the EdgeHD .7x provides generous back focus to accommodate additional

This review would only apply to those using a full frame camera for imaging. Celestron claims it is compatible with full frame, but I have to crop down to nearly APS-C size to get rid of the vignetting and distortions. So, I get a wider field of view but have to crop down to just about where I was at without the focal reducer. Net result, about the same field of view but now one stop faster, but an increase in grain and noise due to using less of the camera sensor.
