The Celestron Reducer Lens .7x for EdgeHD 800 is quite useful and should be in every budding astronomers accessory bag. Easy to connect to your OTA, you should have no problem setting up your telescope with your newly acquired reducer.
Design
The 4-element optical layout is designed specifically for the EdgeHD 800 to maintain the flat-field performance of the EdgeHD optical design. Unlike generic reducers, the EdgeHD .7x provides generous back focus to accommodate an assortment of accessories and a wide variety of cameras.
The Reducer also allows use of existing EdgeHD T-Adapters and other Celestron imaging accessories with or without the Reducer Lens. The EdgeHD .7x Focal Reducer Lens makes your EdgeHD 800 one full f-stop faster than f/10, doubling the equivalent exposure at f/10. It also increases the field of view by 43%, which makes it 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. All air-to-glass surfaces have multiple layers of coating for maximum light transmission and color correction. All lens elements contain blacken edges to minimize internal reflection and maximize contrast. Large diameter lens elements, up to 60 mm clear aperture, ensure that the optimized image circle remains at a generous 42 mm for use with a large CCD sensors.
Illuminated Field
The Reducer is optimized for APS-C sized sensors, including most DSLR cameras and Nightscape CCD cameras
Mechanical Design
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, the reducers offers you an outstanding mechanical design.
Versatility
Provides an intermediate focal length between EdgeHD's native f/10 (or f/11) and the optional Hyperstar accessory at f/2, making the EdgeHD the most complete imaging system in its price range
