    Celestron's newly designed CGX-L computerized equatorial mount is the latest addition to their fully computerized equatorial mount series. It is capable of carrying Celestron’s largest optical tubes with ease with an exceptional load capacity to weight ratio, and is perfect for backyard observatories with its compact design and innovative features that fully support large telescopes, imaging kits, and the latest wireless tech accessories.

    Computerised Mount Features: 

    New CGX-L Features:

    • Increased 34kg load capacity; Exceptional load capacity to weight ratio
    • Additional aux accessory ports and autoguider port on the dec axis for a better cable management system
    • Larger 144mm diameter worm wheels that provide smoother viewing operation and drive heavier loads more accurately
    • Longer 270mm dovetail saddle that support larger optical tubes easily
    • Massive 70 mm stainless steel tripod legs with a wider stance for improved stability under heavy loads
    • New accessory tray holds three 1.25” and two 2” eyepieces with an upright stand for your smartphone or tablet
    • Heavy duty, 31.5 mm stainless steel counterweight shaft to support additional counterweights
    • Optional add-on polar axis finderscope custom designed for CGX and CGX-L
    • Supports WiFi and wireless operation accessories such as StarSense AutoAlign and SkyPortal Wi-Fi Module (sold separately)

    Mount Features:

    • Compact, lower-profile equatorial head provides improved stability and portability; Sturdier and more rigid with quicker dampening time
    • Improved 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
    • Internal cabling for worry-free remote operation. Power input and lower accessory ports remain stationary while the mount slews to avoid snags
    • Internal hard stops for both axes prevent cable tension and tripod strike
    • Internal optical sensors on both axes for simple and safe remote operation
    • Home sensors allow the mount to always start in the index position regardless of orientation before a power reset
    • Limit sensors automatically shut off slewing or tracking before reaching the hard stop fail safe
    • Includes Celestron's new PWI telescope control software that features multi-point mount modeling for extremely precise pointing accuracy
    • Software Polar Align: “All-Star Polar Alignment” allows quick and very precise polar alignment. Align on any bright named star without extra polar alignment accessories, apps, or other assistance
    • Adjustable EQ head position to optimize center of gravity over the tripod and fully utilize the increased 3°-65° latitude range
    • Dual-fit Vixen/CG-5 and Losmandy/CGE dovetail saddle
    • +20° of additional tracking past the meridian on either side
    • Redesigned tripod has a widened stance for added stability. The minimum tripod height has also been lowered per user feedback
    • Tripod legs can be collapsed with accessory tray installed for faster setup and transport

    Improved Ergonomics:

    • Integrated handles for easy transport and portability
    • New ergonomically designed dovetail clamping knobs
    • Innovative and improved polar alignment adjustment system
    • All-new ergonomic adjustment knobs with reduced friction for smooth and easy positioning under full loads. Stationary latitude knob with a newly-designed linkage system greatly reduces the amount of friction when polar aligning the mount. Redesigned azimuth adjustment with low-friction Teflon bearings to make adjustments easy under full load. No more binding, rough adjustments!
    • Easy to read latitude scale


    • NexStar+ hand control with USB port
    • USB 2.0 port used to connect directly to PC with PWI Software
    • 2 available autoguider ports for optimum cable management
    • PEC sensor and PPEC ready
    • Threaded 12VDC power input barrel connector
    • Internal Real Time Clock (keeps time and site information saved)
    • On/Off rocker switch with red LED
