    Celestron .7X Reducer for EdgeHD 1100


    The Celestron .7x Reducer Lens makes your EdgeHD 1100 one full f-stop faster than f/10, reducing your exposure time by one-half to capture the same object brightness. It maintains a similar flat-field performance as the native EdgeHD optical design while increasing the FOV by 43 percent to better capture wide field images.

    The EdgeHD reducer threads directly onto the 3.25 Inch threads of your EdgeHD optical tube.  This reduces mechanical vignetting and allows for use with larger (full frame) sensors and Off-Axis Guiders. It keeps the identical back focus when used at f/10 and provides generous back focus to accommodate additional accessories and a wide variety of cameras.

     

     Features a 5-Element Lens Design...

    The EdgeHD Reducer uses Rare Earth Lanthanum glass elements.  They offer clear, high-contrast viewing while minimizing chromatic aberration.  The lenses are fully multi-coated.  All air-to-glass surfaces have multiple layers of coating for maximum light transmission and color correction.  Each element has blackened edges to minimize internal reflection and maximize contrast.

     

    The 60 mm clear Aperture Lens is optimized for   42 mm image circle for use with large CCD sensors.

     

    The housing is machined aluminum for precise spacing of the optical elements.  There are threaded metal covers for each end of the lens assembly to protect the Reducer's lenses from dust and scratches.

    • Does this work well for visual use too?  Even with wide field (Ethos 100) eyepieces?

      This reducer will work for visual use, but it was designed for imaging. 3 things to remember for any focal reducer: 1) The back focus spacing from a reducer is always more critical than with a flattener, so the edge of field sharpness may suffer with som

    • what is cutoff area of this filter is it 420 or higher

      According to Thousand Oaks, the cutoff on this filter is approximately 420mm.

    • Hello! Does this reducer work with Celestron CGEM 1100? Or it's needed only HD optics, isn't it?

      Unfortunately, this reducer will only work with the EdgeHD optics, not the standard 11" SCT. Please contact us with information about your camera and we can assist you in locating an appropriate focal reducer/ corrector.
