Celestron CGEM II 1100 Schmidt-Cassegrain Product description

  1. Advanced Schmidt-Cassegrain Optics: The revolutionary optical design combines mirrors and lenses, offering a large aperture in a compact, portable form. This 11-inch (279mm) aperture excels in gathering light for both deep-sky objects like nebulae and galaxies, and providing sharp, high-contrast views of planets and the Moon.

  2. Precision CGEM II Mount: The robust German Equatorial Mount (CGEM II) ensures unparalleled stability and tracking accuracy, crucial for long-exposure astrophotography. Its impressive GoTo technology automatically locates and tracks over 40,000 celestial objects with precision.

  3. Versatile Performance: This telescope is a hybrid, a catadioptric telescope, known for its versatility. It's perfectly suited for diverse fields: from serious astrophotography due to its precise tracking and large aperture, to detailed visual observation for both amateur astronomers and enthusiasts.

  4. Enhanced User Experience: Featuring Celestron’s SkyAlign technology for fast, easy setup and a programmable PEC (Periodic Error Correction) to eliminate recurring tracking errors, making it easier to capture crisp celestial images. The mount's ergonomic design allows for quick and comfortable use.

ABOUT THE CELESTRON CGEM II 1100 SCHMIDT-CASSEGRAIN

The Celestron CGEM II 1100 Schmidt-Cassegrain telescope stands out within its series as an ideal instrument for both eager visual observers and dedicated astrophotographers. Its advanced 11-inch (279mm) Schmidt-Cassegrain optical tube, a catadioptric construction, utilizes a unique combination of mirrors and lenses to fold the light path, resulting in a remarkable 2800mm focal length within a compact, manageable design. This allows for exceptional light-gathering capability and high-resolution imaging of celestial objects. Crafted from durable aluminum, the optical tube ensures longevity and maintains optimal performance. Paired with the stable and precise CGEM II German Equatorial Mount, this system is engineered for accurate tracking and minimal vibrations during observations and lengthy astrophotography sessions. It's particularly well-suited for enthusiasts seeking to capture stunning images of distant galaxies, nebulae, and planetary details, making it a powerful tool for backyard astronomy and serious imaging.
