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.
Overview:
The EdgeHD .7x Focal Reducer Lens 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
