Celestron EdgeHD 14" Optical Tube Assembly (CGE Dovetail)

Experience the Universe in HD

EdgeHD is an advanced aplanatic, flat-field Schmidt-Cassegrain telescope designed to deliver crystal-clear, distortion-free images across both wide visual and photographic fields. The optical system is engineered to eliminate more than just off-axis coma, offering an astrograph-quality flat focal plane that stays sharp to the very edges of the view.

True Astrograph Precision

Many instruments marketed as “astrographs” only maintain pinpoint stars along a curved focal surface. While this might suffice for visual observing, it results in blurred stars at the edges when paired with flat digital camera sensors. EdgeHD optics provide a focal plane over three times flatter than a traditional Schmidt-Cassegrain and significantly flatter than competing coma-free systems. The result is razor-sharp stars across even the largest CCD sensors currently available.

Enhanced Imaging Performance

Exceptional edge performance not only yields rounder, more aesthetic star shapes but also improves resolution and limiting magnitude compared to telescopes of similar aperture. With Celestron’s StarBright XLT coatings applied to every optical surface, EdgeHD maximizes light transmission across the full spectrum for both visual use and astrophotography.

Mechanical Innovations

In addition to its optimized optical design, the EdgeHD optical tube incorporates several engineering upgrades to ensure reliable performance night after night.

   ➜  Mirror clutches – Adjustable clutches secure the primary mirror, minimizing image shift during long-exposure astrophotography. Once locked, flexible tension rods stabilize the mirror without adding stress, keeping the image steady on the eyepiece or sensor.

   ➜  Tube vents – Rear-cell vents allow trapped heat to escape from behind the primary mirror. Each vent is fitted with a 50-mesh filter, ensuring warm air exits while dust stays out.

   ➜  Fastar compatibility – EdgeHD is among the most versatile imaging telescopes available. At its native f/11, it delivers the magnification needed for resolving fine details in small deep-sky objects. By adding an optional reducer lens tailored for each EdgeHD size, the field of view can be expanded without compromising quality. Pair it with a Barlow lens for high-power lunar, solar, and planetary imaging. Every EdgeHD tube is also Fastar-ready, allowing the secondary mirror to be swapped for a third-party lens, enabling ultra-fast f/2 wide-field astrophotography.

Individually Verified Quality

Every EdgeHD telescope undergoes thorough quality control. Each unit is tested not only for the precision of its optical surfaces but also as a complete imaging system, using a camera and artificial star. This final acceptance process guarantees that every EdgeHD leaving the factory meets exacting performance standards and is ready to deliver professional-quality astrophotography results in real-world conditions.
