Explore the heavens with the Celestron CGX Equatorial 925 HD Telescope, a state-of-the-art astronomical instrument. This telescope boasts a 9.25" HD Optical Tube Assembly, perfectly complemented by the advanced CGX EQ Mount and Tripod. Enhanced with Celestron’s renowned StarBright XLT coatings, it ensures maximum light transmission for crystal-clear celestial views.

This package includes a 9x50 finderscope for easy and precise object location, a 2” mirror diagonal for comfortable viewing, and a wide-angle 23mm Luminos 2" eyepiece. The CGX 925 HD is an exceptional combination of Celestron's cutting-edge CGX computerized equatorial mount and its acclaimed EdgeHD optical system. With over 9 inches of aperture coated with StarBright XLT, this telescope offers more than 1000 times the light-gathering power of the unaided eye, making it a superior choice for both hobbyists and serious astroimagers.

Experience the Universe in HD with the EdgeHD system, an aplanatic, flat field Schmidt-Cassegrain telescope that delivers aberration-free images across a broad visual and photographic field. The optical design is tailored to reduce not only off-axis star coma but also to provide an astrograph-quality flat focal plane right to the edge of the field of view.

EdgeHD optics are designed to produce a focal plane three times flatter than a standard Schmidt-Cassegrain telescope and significantly flatter than other coma-free designs, ensuring visibly sharp stars across large CCD chips. These optics also improve resolution and limiting magnitude compared to telescopes of equal aperture, thanks to Celestron’s StarBright XLT optical coatings on every surface.

The mechanical features of this telescope are as impressive as its optics. The tube features mirror clutches with flexible tension to hold the mirror in place and reduce image shift during long exposure astro-imaging. Tube vents with integrated 50-mesh filters efficiently release hot air from behind the primary mirror, preventing dust entry. The EdgeHD tubes' Fastar versatility allows for rapid wide-field imaging at f/2.

Each EdgeHD telescope undergoes rigorous testing for surface quality and with a camera and artificial star, ensuring it meets Celestron's strict quality assurance standards. This guarantees top performance in the field and high-quality astroimages.

The CGX mount, an integral part of Celestron’s CGEM series, has been the foundation for German Equatorial telescopes ranging from 6 to 11 inches of aperture. It's designed to enhance both visual and astro-imaging experiences, featuring a lower profile EQ head for a more stable setup, a superior drive system, home and limit optical sensors for remote operation, and improved cable management. Mechanical and ergonomic improvements throughout the mount make it sturdier, easier to use, and transport, solidifying the CGX as a versatile backbone for a wide range of telescopes.
