Explore the cosmos with the Celestron CGX Equatorial 1100 Schmidt-Cassegrain Telescope. This advanced system features an 11" Schmidt-Cassegrain optical tube assembly, crafted from durable aluminum and enhanced with Celestron's superior StarBright XLT coatings. With a focal length of 2800mm (f/10) and a 40mm eyepiece included, offering 70x magnification, this telescope brings the universe closer to you.

The visual back is compatible with 1.25" accessories, expanding your viewing options. A 9x50 finderscope assists in precisely locating celestial objects, while the star diagonal ensures a comfortable viewing experience, especially for high-sky observations. It includes a dovetail rail, compatible with the CGE mount, integrating seamlessly into your setup.

The CGX 1100 Schmidt-Cassegrain, with its optical tube assembly weighing just 27.5 lb, combines portability with extraordinary light-gathering power — 89% more than an 8" telescope and over 40% more than the 9.25" models.

The CGX Mount, a product of Celestron’s extensive experience in German Equatorial mounts, is designed to be the solid foundation for telescopes ranging from 6 to 11 inches in aperture. This mount represents the evolution of backyard telescope technology, catering to both astro-imagers and automated planetarium setups.

Celestron’s CGX EQ mount is the result of years of advancement in design and engineering, focusing on stability, precision, and ease of use. Its low-profile EQ head ensures a compact and stable setup. The mount boasts an improved drive system, is friendly for remote operation with home and limit optical sensors, and offers straightforward polar alignment adjustments. Enhanced cable management and overall mechanical and ergonomic improvements make the CGX mount sturdier, easier to handle, and more convenient to transport.

This mount is Celestron’s commitment to providing a versatile equatorial backbone, capable of supporting a wide array of telescopes for both visual observation and astrophotography.

Solar Warning	Never look directly at the Sun with the naked eye or with an optic (unless you have the proper solar filter). Permanent and irreversible eye damage may result. Never use your optic to project an image of the Sun onto any surface. Internal heat build-up can damage the optic and any accessories attached to it. Never leave your optic unsupervised. Make sure an adult who is familiar with the correct operating procedures is with your optic at all times, especially when children are present.
