Celestron CGEM II 800 Schmidt-Cassegrain

1. Catadioptric Optical Design: The Celestron CGEM II 800 features an 8-inch Schmidt-Cassegrain optical tube by combining mirrors and lenses to produce a long focal length in a compact design. This results in superb resolution, flat-field views, and virtually no chromatic aberration, making it highly versatile for both lunar/planetary observing and deep-sky astrophotography.

2. CGEM II Equatorial Mount: Engineered for stability and precision, the CGEM II mount delivers smooth, accurate tracking essential for long-exposure imaging. Its robust design minimizes vibrations, while the advanced GoTo system, with a database of over 40,000 celestial objects, offers effortless navigation across the night sky.

3. Integrated All-Star Polar Alignment: This innovative feature allows users to perform precise polar alignment on any visible star, significantly simplifying the setup process for observers who may not have a clear view of the celestial pole. This capability enhances tracking accuracy for demanding astrophotography sessions.

4. Flash Upgradeable Hand Control: The included NexStar+ hand control features a USB port, allowing for easy updates to the mount's firmware. This ensures your telescope always benefits from the latest features and bug fixes, enhancing its long-term performance and user experience.

ABOUT THE CELESTRON CGEM II 800 SCHMIDT-CASSEGRAIN

The Celestron CGEM II 800 Schmidt-Cassegrain telescope sets itself apart as a sophisticated and versatile instrument for serious amateur astronomers. Unlike simpler designs, this catadioptric telescope combines the light-gathering power of a large primary mirror with a corrective plate to deliver sharp, high-contrast images free from spherical aberration. Its 8-inch (203mm) aperture excels in resolving fine details on the Moon and planets, while also gathering ample light for observing fainter nebulae and galaxies. Mounted on the acclaimed CGEM II computerized equatorial mount, it offers unparalleled tracking accuracy and a robust platform, making it an ideal choice for both dedicated visual observers and aspiring astrophotographers. The telescope also boasts a Celestron's StarBright XLT optical coating system, maximizing light transmission for brighter images and enhanced contrast, even under challenging conditions. The construction, predominantly from high-quality aluminum and precision-machined components, ensures durability and stability, critical for precise observations and imaging.
