Reducer Lens .7X – EDGEHD 925

39,433.00 excl. 18% GST

  • Fastar compatibility and f/2 imaging with optional accessory: the EdgeHD is the most complete imaging system in its price range.
    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 object
  • 4-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/10 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

Performance

  • Design: 4-element optical layout designed specifically for the EdgeHD 9.25″ to maintain the flat-field performance of the EdgeHD 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 accessories
  • One 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

Glass

  • 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

Full Frame Design

  • 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: 60 mm clear aperture Lens optimized for a 42 mm image circle for use with large CCD sensors.

Mechanical Design

  • 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.
