Celestron 0.7x Focal Reducer Lens for EdgeHD 925 Optical Tubes Astro Telescope

Description: Celestron 0.7x Focal Reducer Lens for EdgeHD 925 Optical Tubes Telescope #94245 Features: 1. The EdgeHD .7x Focal Reducer Lens makes your EdgeHD 9.25" one full F-Stop faster than f/10, reducing your exposure time by half to capture the same brightness of object2. 4-element lens design3. Maintains similar flat-field performance as native EdgeHD optical design4. Increases field of view by 43% to better capture wide field images5. 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 Guiders6. Maintains the identical back focus when used at f/10 and provides generous back focus to accommodate additional accessories and wide variety of cameras7. Allows use of existing EdgeHD T-Adapters with or without the Reducer Lens Specifications: PerformanceDesign: 4-element optical layout designed specifically for the EdgeHD 9.25" to maintain the flat-field performance of the EdgeHD optical designMaintains 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 objectIncrease field of view by 43%: Better for capturing wide-field images of larger galaxies and nebulae GlassLanthanum Glass Elements: EdgeHD reducer uses "rare earth" Lanthanum glass elements for clear, high contrast viewing while minimizing chromatic aberrationFully multi-coated lens elements: All air-to-glass surfaces have multiple layers of coating for maximum light transmission and color correctionBlacken edges: All lens elements have blacken edges to minimize internal reflection and maximize contrast Full Frame DesignThreads directly onto the 3.25" threads of the EdgeHD optical tube: Reduces mechanical vignetting and allows for use with larger (full frame) sensors and Off-Axis GuidersClear aperture: 60mm clear aperture lens optimized for a 42mm image circle for use with large CCD sensors.Mechanical DesignMachined aluminum housing: Computer assisted CNC machined aluminum housing for precise spacing and alignment of the optical elements.Threaded metal covers for both ends of the lens assembly: To protect your investment from unwanted dust and scratches.VersatilityFastar compatibility and f/2 imaging with optional accessory: the EdgeHD is the most complete imaging system in its price range.
