Celestron Reducer Lens .7X EdgeHD TM 1400

Description

• The EdgeHD .7x Focal Reducer Lens makes your EdgeHD 1400 one full F-Stop faster than f/11, reducing your exposure time by half to capture the same brightness of object
• 5-element lens design
• Maintains similar flat-field performance as native EdgeHD 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
• Maintains the identical back focus when used at f/11 and provides generous back focus to accommodate additional accessories and wide variety of cameras
• Allows use of existing EdgeHD T-Adapters with or without the Reducer Lens
• Design: 5-element optical layout designed specifically for the EdgeHD 14" to maintain the flat-field performance of the EdgeHD optical design
• Maintains the same back focus as when used at f/11: 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 accessories
• One full F-Stop faster than f/11: Reduces the exposure time by 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
• Lanthanum Glass Elements: EdgeHD reducer uses "rare earth" Lanthanum glass elements for clear, high contrast viewing while minimizing chromatic aberration
• Fully multi-coated lens elements: All air-to-glass surfaces have multiple layers of coating for maximum light transmission and color correction
• Blacken edges: All lens elements have blacken edges to minimize internal reflection and maximize contrast
• Threads 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 Guiders
• Clear aperture: 60mm clear aperture lens optimized for a 42mm image circle for use with large CCD sensors.
• Machined 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.
• Fastar compatibility and f/2 imaging with optional accessory: the EdgeHD is the most complete imaging system in its price range.
