Celestron EdgeHD 9.25" SCT Optical Tube Assembly

The night sky has always fascinated individuals and with good reason. The heavens are teeming with life, but sadly, most of it is not visible to the naked eye. Now with the study of Astronomy and the invention of telescopes, the moon, stars and planets are all within reach. With the right instruments, there's no telling what you might see.

See the Universe in HD
The Celestron EdgeHD 8" SCT Optical Tube Assembly 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. The EdgeHD OTA has an 9.25" aperture with a focal length of 2350 mm. It comes with a wide-angle 23 mm Luminos 2" eyepiece, a 9x50 finderscope, and a 2" mirror diagonal for more comfortable viewing.

True 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, tube vents and Fastar versatility are just three examples of EdgeHD's newest features.

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).

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.

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 Celestron's rigid quality assurance. This “final acceptance test” confirms the EdgeHD will perform in the field and deliver high-quality astroimages.

Celestron CGX-L Computerized Mount

Celestron's newly designed CGX-L Computerized Equatorial mount is the
latest addition to our fully computerized equatorial mount series.
Capable of carrying Celestron's largest optical tubes with ease, CGX-L
is designed for backyard observatories and remote imagers looking for
exceptional load capacity to weight ratio, compact design, and
innovative features that fully support large telescopes, imaging kits,
and the latest in wireless tech accessories. Key design goals included
larger 144 mm diameter worm wheels which provide smoother operation and
can more accurately drive heavier loads, longer 270 mm dovetail saddle
to support larger optical tubes, remote operation friendly features such
as home and limit optical sensors, easier polar alignment adjustments,
and better cable management overall. In addition to that, we've made
mechanical and ergonomic improvements throughout to make the mount
sturdier, easier to use, and easier to transport. COMPACT. ERGONOMIC.

Celestron CGX-L Tripod

  • Redesigned tripod has a widened stance for added stability. The minimum tripod height has also been lowered per user feedback
  • Tripod legs can be collapsed with accessory tray installed for faster setup and transport

Celestron Counterweight for CGE Pro Telescopes (22lb)

Make sure that your observation of the night sky is clear and accurate with the 22 lb. Counterweight from Celestron! Designed for efficiency and convenience, the telescope accessory balances the overall mass of a telescope’s optical tube working in conjunction with Celestron CGE Pro or CGEM DX equatorial mounts.


The Counterweight is especially effective in off-setting the weight added to your telescope by such heavy items as lens shades and tele-extenders. This balancing process also enables you to increase the weight of visual-side accessories on your telescope, including cameras and refractors, while still maintaining exquisite balance.


Because the Counterweight restores overall balance, it makes use of your telescope simple and more efficient; the balancing process makes handling your equipment easier and improves tracking accuracy. The unit also features a hand-tightened knob which holds it in place on the mount’s counterweight bar.

Perfect balance isn’t required to properly operate your telescope. As a matter of fact, flawless balance is not always possible when using fixed-position weights. But with Celestron’s Counterweight, you can achieve a desired balance and seriously reduce both shaking and swinging even when locks are released.


The Celestron 22 lb. Counterweight for CGE Mount is designed to help balance extra-heavy accessory loads (such as a large photoguide refractor, accessory dovetail, mounting rings, and a camera) on a Celestron telescope mounted on the Celestron CGE Pro or CGEM DX equatorial mounts. It will also let you install and balance a heavy non-Celestron scope on a Celestron CGE Pro or CGEM DX mount (which come with only one 22 pound counterweight as standard equipment when a mount is bought alone).

Featuring all the elements you need to protect your equipment and enrich your astronomical observations, the Celestron 22 lb. Counterweight is the ideal addition to your stargazing set-up!

  • Restores overall balance
  • Makes handling your equipment easier
  • Improves tracking accuracy
  • Seriously reduces both shaking and swinging
  • Designed to help balance extra-heavy accessory loads
