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

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. 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
