Product Description
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. Incorporating computer assisted CNC machined aluminum housing, for precise spacing and alignment of optical elements, and threaded metal covers on the lens assembly to protect your investment from dust and scratches, our reducers offer you an outstanding mechanical design. With the fastar option on all EdgeHD optical systems, coupled with the .7x reducer, your telescope becomes the most complete imaging system available in its price range today. Performance Design: 5-element optical layout designed specifically for the EdgeHD11" to maintain the flat-field performance of the Edge HD optical desig
- The EdgeHD .7x Reducer Makes Your EdgeHD 1100 One Full F-Stop Faster Than f/10, Reducing Your Exposure Time by One-Half to Capture the Same Brightness of Object
- 5-element lens design
- Maintains similar flat-field performance as native Edge HD optical design
- Increases Field of View by 43% to Better Capture Wide Field Images
- Threads Directly onto the 3.25" threads of the EdgeHD which Reduces Mechanical Vignetting and Allows for use with Larger (Full Frame) Sensors and Off-Axis Guiders
