Celestron CGX 800 EdgeHD
Experience the cosmos like never before with the Celestron CGX Equatorial 800 HD Telescope. This advanced setup features an 8-inch HD optical system mounted on Celestron's precise CGX computerized equatorial mount, making it ideal for both avid astronomers and astrophotographers. The telescope's optics are enhanced with Celestron’s premium StarBright XLT coatings, ensuring exceptional light transmission and clear, crisp images.
Included in this package are a 9x50 finderscope for easy object location, a 1.25” mirror diagonal for comfortable viewing angles, and a 1.25” 40mm Plössl eyepiece, enriching your celestial viewing experience. The CGX 800 HD is celebrated for its lightweight and portable design, offering over 800 times the light-gathering power of the naked eye.
The EdgeHD technology in this telescope offers an aplanatic, flat field Schmidt-Cassegrain design that guarantees aberration-free images across a vast field of view. This optical system surpasses typical astrographs by providing a flatter focal plane, essential for sharp imaging with digital camera sensors.
The CGX 800 HD not only excels in delivering beautifully round and sharp stars but also enhances the resolution and limiting magnitude of celestial objects. Its mechanical design is thoughtfully engineered, featuring mirror clutches with flexible tension to reduce image shift and tube vents with integrated filters to manage temperature and dust ingress. The Fastar versatility of the EdgeHD optical tubes allows for rapid wide-field imaging and enhanced astrophotography capabilities.
Every EdgeHD optical system undergoes rigorous testing for surface quality and performance assurance, ensuring that each telescope delivers high-quality astroimages. The CGX mount, a product of Celestron's extensive experience in German Equatorial mount design, has been refined for improved stability, easier polar alignment, enhanced cable management, and remote operation capabilities.
This telescope and mount combination represents Celestron's commitment to providing versatile, high-performance equipment for both visual and photographic exploration of the night sky, making it an exceptional choice for astronomers and astrophotographers seeking a robust, high-quality imaging system.
