Embark on an unparalleled astronomical journey with the Celestron EDGEHD 11" Optical Tube Assembly (CGE Dovetail). This top-tier telescope boasts EdgeHD’s aplanatic, flat field Schmidt-Cassegrain optics, ensuring exceptionally sharp stars across the entire field of view, catering to the demands of the largest imaging sensors and widest eyepieces.

Crafted with an aluminum optical tube, it features innovative tube vents with a 50-mesh filter, effectively releasing hot air from behind the primary mirror. This design not only maintains optimal temperature but also minimizes image shift during long-exposure imaging thanks to the sturdy mirror support knobs.

EdgeHD’s versatile architecture supports three distinct focal ratios: the native f/10, f/7 with an additional focal reducer, and an ultra-fast f/2 for advanced imaging, achievable by removing the secondary mirror and adding third-party accessories.

Celestron's exclusive StarBright XLT coatings ensure maximum light transmission, enhancing your viewing experience. The package is complete with a 9x50 finderscope, a comfortable 2” mirror diagonal, and a wide-angle 23 mm Luminos 2" eyepiece, inviting you to explore the universe in high definition.

EdgeHD stands out as an aplanatic, flat field Schmidt-Cassegrain telescope, engineered to eliminate off-axis star coma and deliver an astrograph-quality, flat focal plane right to the edge of the field of view.

Unlike typical astrographs with a curved focal plane, EdgeHD optics are designed to produce a significantly flatter focal plane, ensuring sharply focused stars across some of the largest available CCD chips, ideal for both visual and photographic applications.

EdgeHD’s superior edge performance not only yields more aesthetically pleasing stars but enhances resolution and limiting magnitude, outperforming telescopes of similar aperture. The StarBright XLT optical coatings further optimize light throughput across a broad spectrum, both visual and photographic.

The telescope’s mechanical features are meticulously designed for optimum performance. Mirror clutches with flexible tension ensure minimal image shift without exerting pressure on the mirror assembly. The rear cell tube vents, equipped with 50-mesh filters, allow for efficient air release while preventing dust ingress.

The Fastar-compatible EdgeHD is remarkably versatile, perfect for capturing detailed deep sky objects at f/10, or wide field images at f/2 with additional accessories. Whether using the reducer lens for a wider field of view or a Barlow lens for high-resolution imaging, the EdgeHD adapts seamlessly to your imaging needs.

Each EdgeHD undergoes rigorous testing, including surface quality checks of optical components and a comprehensive camera and artificial star evaluation, ensuring that each telescope meets Celestron's stringent quality standards. This guarantees that the EdgeHD will deliver exceptional astroimaging performance in real-world conditions.

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.
