Schmidt-Cassegrain C11 EdgeHD 280mm (11″)

Celestron C11 EdgeHD: Optical Excellence to Explore the Universe

Discover the Celestron C11 EdgeHD, a Schmidt-Cassegrain reference telescope that combines state-of-the-art optical performance with advanced mechanical design. Ideal for astrophotography and visual observation, this instrument delivers sharp, aberration-free images right down to the edges of the widest sensors and eyepieces.

Unrivalled Optical Quality

• Ultra-flat field: Eliminates coma and field curvature for perfectly punctual stars across the entire field of view.
• Exceptional focal plane : Three times flatter than a conventional Schmidt-Cassegrain, ideal for imaging with the largest CCD or CMOS sensors.
• Maximum light transmission : Thanks to StarBright XLT coating, each optical surface maximizes light capture for bright, detailed images.

Versatile performance

• Native focal ratio f/10 : Ideal for capturing precise details of deep-sky objects.
• Reduced to f/7 : Increases field of view with optional focus reducer.
• Fast imaging at f/2 with Fastar : Turn your telescope into a high-speed system by removing the secondary mirror and adding a third-party accessory.

Advanced mechanical features

• Primary mirror lock : Reduces mirror movement during long exposures for a stable, centered image.
• Advanced ventilation system : Vents at the rear of the tube ensure rapid dissipation of hot air, while a 50-micron mesh filter keeps out dust.
• Fastar compatibility : Switch to f/2 focal ratio for fast, wide-field imaging.

Rigorous quality testing

Each C11 EdgeHD is meticulously tested to ensure optimum optical and mechanical performance, with final validation via an artificial star and camera to verify image quality and system accuracy.

Accessories Included for a Complete Experience

• 9×50 finder: Find your targets with precision.
• Diagonal 2" mirror: For comfortable observation with wide-field eyepieces.
• Luminos 23 mm (2") eyepiece: Enjoy an immersive, detailed view.

Versatile applications

• Visual observation : Explore planets, the Moon and deep-sky objects with exceptional clarity.
• Advanced astrophotography : Capture precise details of nebulae, galaxies and star clusters.
• Fast imaging with Fastar : Ideal for short, efficient imaging sessions.

Conclusion

The Celestron C11 EdgeHD is the ultimate tool for astronomy enthusiasts seeking exceptional performance and uncompromising versatility. Explore the universe with an instrument designed to push the limits of your celestial discoveries.
