Product Details

  • The Celestron EdgeHD 800 .7X Focal Reducer features a custom 4-element optical design engineered to maintain the flat-field performance of the EdgeHD optics. Unlike generic reducers, this premium reducer provides substantial back focus (105 mm) to accommodate an assortment of imaging accessories.

    Experience high-contrast viewing with minimal chromatic aberration with the EdgeHD 800

    Offering extra-low dispersion, its exotic Lanthanum elements provide mesmerizing views. All air-to-glass lens surfaces of the .7X Focal Reducer Lens feature multiple layers of coating for maximum light transmission and color correction. Enjoy blackened edges that minimize internal reflection and maximize image contrast!

    The aluminum housing of the focal reducer has been designed and CNC machined for precise spacing and alignment of the optical elements. Store and transport your reducer safely with its featured threaded metal caps, included as well.

    • Increase The 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.
    • Optimized for APS-C sized sensors: Including most DSLR cameras and Nightscape CCD cameras
    • Machined Aluminum Housing: Computer-assisted CNC machined aluminum housing for precise spacing and alignment of the optical elements.
    • Threaded Metal Covers for Both Ends of The Lens Assembly: To protect your investment from unwanted dust and scratches.
    • Complete Image System: Provides an intermediate focal length between the telescope (f/10) and the optional Hyperstar accessory at f/2, making the EdgeHD the most-complete imaging system in its price range.

    Celestron .7 reducer

    I am very happy with my new reducer! It appears to good clarity, nice, round stars. It gives my telescope more versatility making it easier to get the shots I want. It is hefty and has a well built feel to it.

    Telescope was sent back to Celestron for repair so haven’t had a chance to even look through it

    A must for astrophotographers

    Having tested it just once, I managed to picture some stars in the middle of my light polluted city, with just a short exposure (30 s). Sturdy build quality, looking forward for clear skies to go for longer exposures!

    Nice High Quality Reducer

    While it works great, just be aware, if you get it for the ES 127mm you have to buy a separate adapter for it as the ones that come with it do not work with the stock focuser.
