The Celestron EdgeHD 925 0.7x Reducer is a 4-element corrector for the EdgeHD 9.25" 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 9.25" 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 9.25" becomes 1645mm, giving an excellent field of view for galaxies. The flattener/reducer has a backfocus requirement of 146.05mm, leaving plenty of room for accessories. The field correction is suitable for full frame sensors such as the ASI6200.

All air-to-glass optical surfaces have multiple layers of coatings for maximum light transmission and colour correction. Additionally, each lens has blackened edges to minimize internal reflections and maximize contrast. The CNC-machined aluminium housing keeps the elements secure and precisely aligned.
