Celestron EdgeHD 11" Optical Tube Assembly

The Celestron EdgeHD 11" Optical Tube Assembly (OTA) is engineered for advanced astronomers seeking premium performance, flat-field imaging, and superior optical precision. Built with Celestron’s EdgeHD aplanatic optics, this 11-inch Schmidt-Cassegrain telescope delivers razor-sharp, edge-to-edge clarity with a focal plane up to three times flatter than standard SCT systems. Combined with StarBright XLT Coatings for maximum light transmission, the Celestron 11" EdgeHD is ideal for astrophotography, visual astronomy, planetary observation, and deep-sky imaging, making it a top choice for retailers and wholesale suppliers serving serious astronomers.

• Large 279.4mm (11") Aperture:  A generous 11-inch aperture offers exceptional light-gathering capability, perfect for resolving faint galaxies, nebulae, and star clusters with stunning detail, an essential selling point for retailers targeting advanced users.
• 2800mm Focal Length (f/10): The long f/10 focal ratio makes the Celestron 11" EdgeHD a powerhouse for high-resolution planetary imaging and detailed lunar viewing, delivering crisp, contrast-rich visuals.
• Aplanatic, Flat-Field EdgeHD Optics: The EdgeHD system eliminates coma and curvature, ensuring a true flat-field image ideal for full-frame astrophotography.
• StarBright XLT Optical Coatings: Celestron's premium coatings enhance image brightness, colour fidelity, and contrast, giving the OTA superior performance compared to standard Schmidt-Cassegrain telescopes.
• CGE Dovetail Bar Included: A secure, widely compatible dovetail mounting system ensures easy integration with various equatorial mounts, making this 11-inch OTA highly versatile for both amateurs and professional observatories.

Exclusive EdgeHD Technologies

The Celestron EdgeHD 11" SCT includes advanced engineering features not found in traditional Cassegrain telescopes:

• Mirror Clutches for Precision Stability: Integrated mirror tension clutches minimize image shift, keeping celestial objects centered during long-exposure astrophotography, guiding, and high-magnification observation.
• Rear Cell Cooling Vents: Built-in cooling vents release warm air behind the primary mirror, allowing faster thermal equilibrium for sharper, more stable viewing conditions.
• FASTAR-Compatible for f/2 Imaging: Retailers can highlight the OTA’s ability to convert from f/10 to f/2 using a separate FASTAR adapter. This turns the telescope into an ultra-fast astrograph, perfect for wide-field deep-sky imaging, one of the most powerful benefits for astrophotographers.

Premium Manufacturing & Quality Control

Every Celestron EdgeHD 11" OTA undergoes strict optical testing. Each unit is inspected by trained engineers using artificial stars and high-resolution imaging systems to guarantee superior optical alignment and performance. This meticulous quality control ensures that every C11 SCT meets Celestron’s professional-grade standards, making it a dependable choice for wholesalers, retailers, and astronomy educators.
