  Celestron EdgeHD 8" OTA at a Glance

  • Mirror Support Knobs and Flexible Tension Clutches - hold the mirror in place and reduce image shift when rotating the tube around the mount.
  • Tube Cooling Vents - located on the rear cell allow hot air to be released from behind the primary mirror.
  • Fastar Versatility - All EdgeHD optical tubes are Fastar compatible for imaging down to f/2 with optional accessories.
  • Brighter Star Images - Light becomes more concentrated when focused precisely. This maximizes image brightness.
  • Dovetail Plate - for attaching to CGE mounts.
  • Sturdy Handle and Large Focusing Knob for your ergonomic needs.

  Special Features of the Celestron EdgeHD 8" OTA

  True Astrograph Quality

  EdgeHD optics produce a focal plane more than three-times flatter than a standard Schmidt-Cassegrain telescope and dramatically flatter than competing coma-free designs. This guarantees you visibly sharp stars across some of the largest CCD chips available today. 

  Improved Performance

  Superior edge performance not only creates a rounder, more pleasing stars but actually improves the resolution and limiting magnitude when compared to telescopes of equal aperture. With Celestron’s StarBright XLT optical coatings on every surface, EdgeHD optics gives you maximum light across the widest visual and photographic spectrum.

  Mechanical Features

  In addition to EdgeHD’s optimized optical design, the telescope tube has been redesigned to make sure you get the most from your optics each and every night.

  • Mirror Clutches -Flexible tension clutches hold the mirror in place and reduce image shift when taking long-exposure astro-images. Once focused, the flexible rods allow the mirror to be held in place without putting any force or pressure on the mirror assembly, keeping the image centered in the eyepiece (or on the sensor).
  • Tube Vents - Cooling vents located on the rear cell allow hot air to be released from behind the primary mirror. Each vent has an integrated 95-micron micromesh filter guaranteed to let warm air out without letting dust in.
  • Fastar Versatility - All EdgeHD optical tubes are Fastar-compatible, allowing the secondary mirror to be removed and replaced with a third party lens accessory for ultra-fast f/2 wide-field imaging. Add the optional reducer lens—custom-designed for your size EdgeHD tube—and you can increase your field of view without sacrificing optical performance.

  Individually Tested

  Every EdgeHD that ships have been tested not only for the surface quality of each optical component but also with a camera and artificial star to ensure the imaging system meets our rigid quality assurance. This “final acceptance test” confirms the EdgeHD will perform in the field and deliver high-quality astro-images.
