Celestron CGEM II 1100 HD Product description

  1. Advanced EdgeHD Optics: The EdgeHD optical design provides aberration-free images across a wide field of view, making it ideal for astrophotography. This aplanatic Schmidt-Cassegrain system delivers pinpoint stars to the very edge of the sensor.

  2. Robust CGEM II Mount: The CGEM II German Equatorial Mount is designed for serious visual observers and imagers. Its superior GoTo accuracy, heavy-duty construction, and permanently programmable periodic error correction (PEC) ensure stable tracking and precise object location.

  3. Exceptional Compactness: As a catadioptric telescope, specifically a Schmidt-Cassegrain, the 1100 HD offers a very long focal length in a short, portable tube. Its closed tube design minimizes dust ingress and reduces maintenance, ideal for versatile use from backyard observing to remote astrophotography.

  4. Versatile Usage: This setup excels in both visual observation of planets and deep-sky objects, and high-resolution astrophotography. Its large 280mm aperture gathers substantial light for bright, detailed views, while the precise tracking accommodates long-exposure imaging.

ABOUT THE CELESTRON CGEM II 1100 HD

The Celestron CGEM II 1100 HD stands out in the market by integrating Celestron's cutting-edge EdgeHD optical system with the robust CGEM II computerized GoTo German equatorial mount. Unlike standard Schmidt-Cassegrain telescopes, the EdgeHD aplanatic design ensures flat-field, coma-free images, delivering stars that are perfectly round from the center to the very edge of your camera sensor or eyepiece field, which is critical for high-quality astrophotography. This catadioptric telescope is engineered for both demanding astrophotographers and visual observers seeking superior performance. Its large 11-inch (280mm) aperture provides incredible light-gathering capability, revealing faint deep-sky objects and intricate planetary details. The combination of its portable main tube, advanced optics, and the stable, precise tracking of the CGEM II mount makes it an exceptionally versatile instrument for a wide range of astronomical pursuits, ensuring sharp, high-contrast views and excellent imaging results.
