CELESTRON 0.7x REDUCER FOR EDGEHD 800 M92 If you aren't sureThe Celestron EdgeHD 800 0. 7x Reducer is a 4 element corrector for the EdgeHD 8" telescope. The flattener reducer uses extra low dispersion lanthanum glass elements for excellent chromatic correction and high contrast. The 0. 7x reduction factor shortens the focal ratio of the EdgeHD 8" to f 7, halving the exposure time and increasing the field of view by 43%. When paired with this flattener reducer, the focal length of the EdgeHD 8" becomes 1422mm,
