This dedicated 0.7× reducer brings the EdgeHD 14 to f/7 for shorter exposures and a wider field. Its five-element design, made specifically for the 14-inch EdgeHD, includes extra-low-dispersion and lanthanum elements and maintains the EdgeHD's flat field.
The reducer threads directly onto the EdgeHD's 3.25-inch rear thread, which reduces mechanical vignetting and allows full-frame sensors and off-axis guiders. Lens elements up to 60 mm clear aperture keep the optimised image circle at 42 mm. Back focus stays at 146 mm, the same as without the reducer, so existing EdgeHD T-adapters still work.
