CGE Mount

New Celestron CGX GOTO computerized equatorial mount features 25 Kg payload, Nexstar+ handbox, tripod, 2 x 5 Kg counterweight and new remote control software.

For eight years, Celestron’s workhorse CGEM mount lineup has been the German Equatorial backbone for telescopes ranging from 6 to 11 inches of aperture. Since that time, many more astro-imagers and planetarium controlled setups have emerged as backyard telescope technology has evolved. Celestron’s engineering team applied their years of experience designing German Equatorial mounts to the all-new CGX EQ, a culmination of all the advancements made to our technologies, value, and ease-of-use.

The new CGX was designed to better support your telescope for both visual and astro-imaging pursuits.  Key design goals included a lower profile EQ head, which provides a more compact and therefore more stable setup; a better drive system; remote operation-friendly with home and limit optical sensors; easier polar alignment adjustments; and better cable management. In addition to that, we’ve made mechanical and ergonomic improvements throughout to make the mount sturdier, easier to use, and transport. The CGX is our new Equatorial backbone to support a wide range of telescopes.

Overview

All-new design. Sturdier and more rigid with quicker dampening time. Increased load capacity to 55 lbs. Improved motors provide more torque, better slewing and tracking under heavy loads. Heavy Duty belt-drive system minimizes backlash while providing smooth motor operation under heavy loads.

Smootherbelt Drivesystem

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 accessory ports remain stationary while the mount slews to avoid snags. Internal hard stops for both axes prevents cable tension and tripod strike.

Mechanical Hard Stops

Internal optical sensors on both axes for simple and safe remote operation


Home And Limit Sensors

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. Brand new control software developed in conjunction with PlaneWave Instruments for professional level control operation and imaging. Software includes multi-point mount modeling for extremely precise pointing accuracy and many more additional features for remote astroimaging.

Wider tripod stance for improved stability.

Adjustable EQ head position to optimize center of gravity over the tripod and fully utilize the increased 3º-65º latitude range.

Dual-fit CG-5/Vixen and CGE/Losmandy dovetail saddle.

Dual Dovetail Saddle

Improved tripod includes:

2" steel legs with height index marks for quick leveling. "Jack of all trays" can hold three 1.25" eyepieces, two 2" eyepieces, your smartphone, or other accessories. +20º of additional tracking past the meridian on either side. Tripod legs can be collapsed with accessory tray installed for faster setup and transport.

Tripod

Improved ergonomics:

Two handles for easy pickup and transport

Ergonomic Carry Handles

All-new ergonomically designed dovetail clamping knobs. Innovative and improved polar alignment adjustment system.

Polar Alignment Adjustment System

All-new ergonomic latitude adjuster for smooth and easy adjustment under full loads.

Optional add-on polar axis finderscope - coming soon
