Engineered to bridge the gap between their Advanced VX & heavy-duty CGX-L mounts, the Celestron CGEM II GoTo German Equatorial Mount delivers the performance required for capturing clear images during astrophotography sessions or resolving dim details when observing through an eyepiece. To make it compatible with a wide assortment of optical tube assemblies, Celestron outfitted the CGEM II with a dovetail saddle designed to accept the standard Vixen-style (Celestron's CG-5) and the larger Losmandy (Celestron CGE) dovetail bars.





Through the use of high-torque dual-axis low-cog DC servo motors, optical encoders on the motors, backlash compensation, and Permanent Periodic Error Correction (PPEC) the mount is capable of precise positioning and tracking accuracy to ensure your target object stays centered while constantly improving its performance the more you use it.





The brain of the system is the NexStar computer controller, which is equipped with a database of over 40,000 objects, including the planets, stars, nebulae, galaxies, and the complete Messier catalog; it can also be programmed with up 100 custom user-defined objects with filters to create custom object lists. Its intuitive menu-driven user interface makes observing the sky, day and night, fast and easy. Features such as guided tours, extended information on 200 popular objects, and multiple alignment options make the NexStar controller an invaluable tool to new users and experienced stargazers alike.The Celestron CGEM II Tripod has 2" diameter steel legs with graduated markings that make it easy to extend the legs to the same height. It comes with a 17 lb counterweight.The Celestron CGEM II Tripod has 2" diameter steel legs with graduated markings that make it easy to extend the legs to the same height.

A large thumbscrew allows you to lock the weight anywhere along the counterweight shaft to allow for precise balance.Use the Celestron 11 lb Counterweight by itself or with other weights to balance your OTA and accessories on Celestron CG-5, CGEM, CG-4 mounts; or any similar mount with a 0.75" (19mm) center bore hole. A large thumbscrew allows you to lock the weight anywhere along the counterweight shaft to allow for precise balance.Outfitted with a large aperture, long effective focal length, and their proprietary StarBright XLT optical coatings, the Celestron C9 1/4-A XLT 9.25" f/10 Schmidt-Cassegrain Telescope provides power and portability. The coating system consists of anti-reflection coatings on the corrector plate, highly reflective index mirror coatings, and low-absorption/high-transmission glass components to ensure that the maximum amount of light is gathered and transmitted to your eye. This system ensures bright and clear high-contrast images with accurate color rendition across the entire visual spectrum without visible distortion at the edges. Celestron includes a standard 1.25" visual back to accept eyepieces and accessories such as the 25mm eyepiece and 90° diagonal supplied with the optical tube assembly (OTA). This OTA is offered here without a mount or tripod for users who already have a support system. Just ensure the mount's payload capacity exceeds 20 pounds to safely carry the weight and that the mount has a Losmandy-style saddle to match the OTA's CGEM mounting plate.Outfitted with a large aperture, long effective focal length, and their proprietary StarBright XLT optical coatings, the Celestron C9 1/4-A XLT 9.25" f/10 Schmidt-Cassegrain Telescope provides power and portability.
