Product Details

  • 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% 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.

    GAIN BETTER ASTRO-IMAGING AND VIEWING WITH THE CELESTRON EDGEHD 1100 .7X REDUCER

    • Quality Design: 5-element optical layout designed specifically for the EdgeHD 1100 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 accessories and a wide variety of cameras. It also allows use of existing EdgeHD T-Adapters and other Celestron imaging accessories.
    • One Full F-stop Faster Than f/10: Reduces the exposure time by one-half to capture the same brightness of object.
    • Increase Field of View by 43%: Better for capturing wide-field images of larger galaxies and nebulae.
    • Lanthanum Glass Elements: EdgeHD reducer uses "rare earth" Lanthanum glass elements for clear, high contrast viewing while minimizing chromatic aberration.
    • Fully Multi-coated Lens Elements: All air-to-glass surfaces have multiple layers of coating for maximum light transmission and color correction.
    • Blackened Edges: All lens elements have blackened edges to minimize internal reflection and maximize contrast.
    • Full Frame Design: Threads directly onto the 3.25-inch threads of the EdgeHD optical tube. Reduces mechanical vignetting and allows for use with larger (full frame) sensors and Off-Axis Guiders.
    • Clear Aperture: 60 mm clear aperture lens optimized for a 42 mm image circle for use with large CCD sensors.
    • Machined Aluminum Housing: Computer-assisted CNC machined aluminum housing for precise spacing and alignment of the optical elements.
    • Threaded metal covers for both ends: To protect your investment from unwanted dust and scratches.
    • Optimized Versatility: Fastar compatibility and f/2 imaging with optional accessory. The EdgeHD is the most complete imaging system in its price range.
