More product information
This Celestron EdgeHD 0.7x focal reducer is a 5-element lens system that converts your 14" f/11 Celestron EdgeHD scope or optical tube into a fast f/7.7 optical system. It threads directly onto the 3.25" rear cell threads of all 14” EdgeHD optical tubes, in front of your imaging equipment. It increases your photographic field of view by 43% to better capture wide field images and cuts your deep space exposure times in half, all the while maintaining the flat-field performance of the native Edge HD optical design.

This Celestron EdgeHD reducer has high index optical elements, including exotic extra low dispersion rare-earth Lanthanum elements, to provide high contrast viewing while minimizing chromatic aberration. All air to glass lens surfaces are fully multicoated for maximum light transmission and color correction. Lens edges are blackened to minimize internal reflection and maximize image contrast. Large diameter lens elements, up to 60 mm clear aperture, ensure that the optimized image circle remains at a generous 42mm for use with large CCD sensors.

The system maintains the same back focus at its faster f/7.7 focal ratio (nominally 146mm from the rear flange of the reducer to the image plane within your camera) as it has when your 14” scope is used at f/11. This generous back focus accommodates a wide variety of cameras and imaging accessories.

Threading the CNC machined aluminum housing reducer directly onto the rear cell reduces mechanical vignetting and allows for use with larger (full frame) sensors and off-axis guiders. The CNC machined aluminum housing assures precise spacing and alignment of the optical elements. Threaded metal covers on both sides of the lens assembly protect your investment from dust and scratches. The housing duplicates the rear cell threading of the scope body so you can use of your existing EdgeHD T-adapters with or without the reducer in place.
