Celestron 91523 overview

  • 1Description

Celestron updates their venerable and versatile mid-level mount with the CGEM II GoTo EQ Mount. Engineered to carry a 40-pound payload and high-torque dual DC servo motors, it is able to smoothly and accurately slew and track heavier optical tube assemblies (OTAs) and rigs up to an 11" Schmidt-Cassegrain. Its Vixen/Losmandy dual dovetail saddle makes the mount compatible with most plates used today. Celestron also improves its usage by adding compatibility with their SkySync GPS unit for a higher level of precision during setup and alignment. To provide a stable platform for the mount and your OTA, a heavy-duty stainless steel tripod is included that sports large 2" legs and an accessory tray that doubles as a stabilizer.

The brain of the CGEM II is the NexStar+ computer controller. Equipped with a database of 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 added for custom object lists. Its intuitive menu-driven user interface provides the power to observe the heavens with nine slew speeds and three tracking rates, plus anti-backlash compensation and Permanent Periodic Error Correction (PPEC) for smoother movements in the motors and improved tracking over time. Features such as guided tours, extended information on 200 popular objects, and multiple alignment options make the NexStar+ controller easy to use and invaluable to new users and experienced stargazers.
