Manufacturer Description

SEE THE UNIVERSE IN HD
EdgeHD is an aplanatic, flat field Schmidt-Cassegrain telescope that produces aberration-free images across a wide visual and photographic field of view. The optical system was designed to reduce more than just off-axis star coma; it also provides an astrograph-quality flat focal plane all the way to the edge of the field of view. 

TRUE ASTROGRAPH QUALITY
Many optical designs that advertise themselves as "astrographs" actually only produce pinpoint stars across a curved focal plane. While this may be acceptable for some visual observing, stars will appear out of focus at the edge when used with the flat chip sensor of a digital camera. 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. Learn more about EdgeHD technology.

IMPROVED PERFORMANCE
Superior edge performance not only creates 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 throughput 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 - EdgeHD is the most versatile imaging telescope available today. At its native f/10, you can achieve the image scale necessary to capture the smallest of deep sky objects. Add the optional reducer lens—custom-designed for your size EdgeHD tube—and you can increase your field of view without sacrificing optical performance. A Barlow gives you added power for high-resolution planetary, lunar and solar imaging. 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.

INDIVIDUALLY TESTED
Every EdgeHD that ships has 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 astroimages.

      5.0 14" Edge SCT

      Pros:

      Cons:

      Comments:

      I owned a Celestron C14 SCT for a few years (along with a 9.25" SCT, a 6" triplet APO refractor and a 10" Newt). I've been a visual astronomer for 42+ years. I've always wondered how much better the views would be with an Edge version over the C14 so I decided to upgrade. While the center 25 percent of the FOV isn't significantly better (possibly more pinpoint stars but I wasn't able to do a side by side), there is an improvement at the edge of the field of view. I especially enjoy open clusters and lunar views much more in the Edge 14" scope. If I had known then what I know now I would have gone with the Edge to begin with.
