Celestron .7x Focal Reducer for 9.25" EdgeHD Telescope
Enhance Your Astrophotos with the Official 0.7X Focal Reducer for the Celestron 9.25" EdgeHD!
The Celestron 0.7x Focal Reducer will bring flat-field performance to your 9.25" EdgeHD, while also providing a 43% wider field of view and faster optics. With plenty of back focus, this reducer is compatible with a variety of imaging accessories.
EdgeHD focal reducers are built with extra-low dispersion Lanthanum lens elements, which provide high contrast views while minimizing chromatic aberration. All air-to-glass lens surfaces feature multiple layers of coating for maximum light transmission and color correction, and all lens elements have blackened edges to minimize internal reflection and further protect image contrast. This reducer threads directly onto the 3.25" threads of the EdgeHD optical tube, which reduces mechanical vignetting and allows for use with larger (full frame) sensors and Off-Axis Guiders. With a 60mm clear aperture lens, this reducer is optimized for a 42mm image circle for use with large CCD sensors.
4-Element Optical Accessory Built with Lanthanum glass
The 0.7x Focal Reducer is the go-to optical accessory for anyone looking to capture stunning photos of larger galaxies and nebulae with their 9.25" EdgeHD telescope. Learn more below!
0.7X Reduction
Featuring a 4-element optical design crafted and optimized specifically for 9.25 EdgeHD optics, this 0.7x focal reducer will bring you faster exposures, wider views, and a flat field performance. Unlike generic focal reducers, the EdgeHD 0.7x maintains the same back-focus as when used at f/10, meaning you'll have plenty of back-focus to accommodate additional accessories and a wide variety of cameras. At a full F-Stop faster than f/10, your exposure times will be faster, meaning you can capture more signal over in a single imaging session. With the 43% wider FOV, you'll have access to larger galaxies and nebulae.
