Celestron EdgeHD 1100

1. Aplanatic EdgeHD Optics: The EdgeHD 1100 is an advanced type of catadioptric telescope, specifically an aplanatic Schmidt-Cassegrain. This innovative design corrects for both coma and field curvature, delivering a perfectly flat focal plane and pinpoint stars right to the edge of the field of view. This makes it an exceptional instrument for high-resolution astrophotography and critical visual observation.

2. Superior Light Gathering and Resolution: Featuring an impressive 11-inch (279mm) aperture, this telescope excels at gathering abundant light, revealing faint deep-sky objects with remarkable clarity and resolving fine details on planets and the Moon. Its StarBright XLT coatings further enhance light transmission, ensuring bright, high-contrast images.

3. Optimized for Imaging: Designed from the ground up for serious imagers, the EdgeHD 1100 boasts a generous back focus and built-in tube vents with filters for optimal thermal management. Its Fastar/HyperStar compatibility allows it to transform into an ultra-fast f/2 imaging system, dramatically reducing exposure times and expanding imaging possibilities.

4. Robust and Versatile Construction: Constructed from durable aluminum, the optical tube assembly is built for stability and longevity. While powerful, its compact design for an 11-inch instrument makes it more manageable for transport and setup, suitable for both backyard astronomy and advanced research-grade applications.

ABOUT THE CELESTRON EDGEHD 1100

The Celestron EdgeHD 1100 stands out in its series as an advanced evolution of the classic Schmidt-Cassegrain telescope, specifically engineered to provide a coma-free and flat focal plane. Unlike standard SCTs, the EdgeHD optical design incorporates a sophisticated two-element field corrector lens group within the optical tube, ensuring that stars remain tack-sharp and spherical right to the extreme edges of the wide field of view. This innovative aplanatic optical system virtually eliminates field curvature and off-axis coma, which are common aberrations in traditional telescopic designs. The EdgeHD 1100 is ideally suited for serious astrophotography, delivering stunning, distortion-free images that maximize the resolution of modern large-format imaging sensors. Beyond imaging, its superb optical quality, coupled with StarBright XLT coatings enhancing light transmission, also makes it an outstanding choice for high-magnification visual observation of planets, the Moon, and faint deep-sky objects. Constructed with robust aluminum, this catadioptric telescope offers exceptional light-gathering power in a relatively compact and manageable form factor.
