Discover the pinnacle of Celestron's optical innovation with the EdgeHD 1100 OTA - CGE.

This telescope features state-of-the-art aplanatic, flat field Schmidt-Cassegrain optics, ensuring exceptionally clear, aberration-free images right to the edges of the largest imaging sensors and eyepieces available.

The EdgeHD 1100 OTA is encased in a robust aluminum tube with strategically placed vents, complete with a 50-mesh filter, for efficient heat dispersion from behind the primary mirror. This design also includes mirror support knobs to secure the mirror and minimize image shift during extended imaging sessions.

This telescope is incredibly versatile, offering three focal ratios: the native f/10, f/7 with an additional focal reducer, and an ultra-fast f/2 for wide-field imaging when you swap out the secondary mirror and add third-party accessories. Celestron's high-end StarBright XLT coatings on every optical surface ensure maximum light transmission for breathtaking views and photographs.

Included with the EdgeHD 1100 OTA are a 9x50 finderscope, a 2” mirror diagonal for more comfortable viewing, and a wide-angle 23 mm Luminos 2" eyepiece, allowing you to experience the Universe in unparalleled HD.

The EdgeHD optical system transcends typical astrograph quality by producing a focal plane over three times flatter than standard Schmidt-Cassegrain telescopes. This delivers incredibly sharp stars across a wide field, satisfying even the largest CCD chip demands for astrophotography.

EdgeHD's superior optical performance not only yields aesthetically pleasing, round stars but also enhances the telescope's resolution and limiting magnitude, setting a new standard for telescopes of similar aperture. Thanks to the extensive StarBright XLT optical coatings, the EdgeHD offers exceptional light transmission across both visual and photographic spectrums.

The mechanical design of the EdgeHD has been refined to match its superior optical performance:

Mirror Clutches: The flexible tension clutches hold the mirror in place, reducing image shift during long-exposure astrophotography. These clutches maintain image centering without exerting undue pressure on the mirror assembly.
Tube Vents: Rear cell cooling vents, equipped with a 50-mesh filter, allow hot air to escape without letting in dust.
Fastar Versatility: The EdgeHD's Fastar compatibility lets you remove the secondary mirror and use a third-party lens for ultra-fast f/2 wide-field imaging. With optional accessories like a reducer lens or a Barlow, the EdgeHD adapts to various imaging requirements.

Each Celestron EdgeHD undergoes rigorous testing, including a thorough inspection of each optical component and a final acceptance test using a camera and artificial star. This ensures that each EdgeHD 1100 OTA delivered meets Celestron's strict standards for quality and performance in astrophotography.

Solar Warning	Never look directly at the Sun with the naked eye or with an optic (unless you have the proper solar filter). Permanent and irreversible eye damage may result. Never use your optic to project an image of the Sun onto any surface. Internal heat build-up can damage the optic and any accessories attached to it. Never leave your optic unsupervised. Make sure an adult who is familiar with the correct operating procedures is with your optic at all times, especially when children are present.
