Discover the Celestron 11" Schmidt-Cassegrain Optical Tube Assembly, a premium astronomical tool crafted with an aluminum optical tube and enhanced by Celestron's exclusive StarBright XLT coatings for optimal light transmission. This assembly boasts a 2800mm focal length (f/10) and includes a 40mm eyepiece, offering 70x magnification. Designed for versatility, the visual back is compatible with 1.25" accessories, and a 9x50 finderscope is included to ensure precise object location. The star diagonal enhances comfort during observation, especially for objects positioned high in the sky. This package also features a dovetail rail compatible with the CGE mount.

Celestron's CGX-L Computerized Equatorial Mount, the latest innovation in their fully computerized equatorial mount series, effortlessly supports Celestron’s largest optical tubes. The CGX-L is tailored for backyard observatories and remote imagers, offering an outstanding load capacity to weight ratio, compact design, and cutting-edge features essential for supporting large telescopes, comprehensive imaging kits, and the newest wireless technology accessories.

The mount's design focuses on key features like larger 144mm diameter worm wheels for smoother operation and precise driving of heavier loads, and a longer 270mm dovetail saddle to accommodate larger optical tubes. Designed with remote operation in mind, it includes user-friendly components such as home and limit optical sensors, simplified polar alignment adjustments, and enhanced cable management. Mechanical and ergonomic advancements have been integrated throughout the mount, making it more robust, easier to operate, and more transportable. The Celestron 11" Schmidt-Cassegrain Optical Tube Assembly combined with the CGX-L Mount embodies a blend of COMPACT, ERGONOMIC, and INNOVATIVE design, setting a new standard in advanced astronomical instruments.

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.
