Celestron CGX-L Equatorial 925 Schmidt-Cassegrain 235mm Telescope - 12070

Celestron's CGX-L Computerized Equatorial mount is the latest addition to our fully computerized equatorial mount series. Capable of carrying Celestron’s largest optical tubes with ease, CGX-L is designed for backyard observatories and remote imagers looking for exceptional load capacity to weight ratio, compact design, and innovative features that fully support large telescopes, imaging kits, and the latest in wireless tech accessories.

Key design goals included larger 144mm diameter worm wheels which provide smoother operation and can more accurately drive heavier loads, a longer 270mm dovetail saddle to support larger optical tubes, remote operation-friendly features such as home and limit optical sensors, easier polar alignment adjustments, and better cable management overall. In addition to that, we’ve made mechanical and ergonomic improvements throughout to make the mount sturdier, easier to use, and easier to transport.

Key Benefits:

Mount Features:

  • Compact, lower profile equatorial head provides improved stability and portability. Sturdier and more rigid with quicker dampening time
  • Motors provide more torque, better slewing and tracking under heavy loads
  • Heavy duty belt-drive system minimizes backlash while providing smooth motor operation at full capacity
  • Clear windows built into motor covers so pulleys and belts can be monitored
  • Spring-loaded brass worm wheel and stainless steel worm gear reduce friction and provide optimum gear mesh

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.
