CELESTRON REDUCER LENS .7X FOR EDGE HD 1100
#94241


Celestron’s new EdgeHD reducers feature a custom 5 element optical design
engineered to maintain the flat-field performance of our award winning EdgeHD
optical system. Unlike generic reducers, our premium reducers provide substantial
back focus to accommodate an assortment of imaging accessories.
EdgeHD reducers offer high index optical elements, including extra low dispersion,
exotic Lanthanum elements, which provide high contrast viewing while minimizing
chromatic aberration. All air to glass lens surfaces feature multiple layers of
coating for maximum light transmission and color correction and contain blacken
edges 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
42 mm for use with large CCD sensors.
5-element optical layout designed specifically for the EdgeHD11" to maintain the flat-field performance of the Edge
HD optical design. Maintains the same back focus as when used at F/10: Unlike generic reducers the EdgeHD .7x
provides generous back focus to accommodate additional accessories and a wide variety of cameras. Also allows
use of existing EdgeHD T-adapters and other Celestron imaging accessoriesOne full F-Stop faster than f/10:
Reduces the exposure time by one-half to capture the same brightness of object Increase field of view by 43%:
Better for capturing wide field images of larger galaxies and nebulae
