Celestron CGX Computerized German Equatorial Telescope Mount

The Celestron CGX Computerized German Equatorial Telescope Mount was designed to better support your telescope for both visual observing and astro-imaging. It's made to be compact, studier, easier to setup/polar align, remote operation-friendly, and overall easier to use than other equatorial mounts.

The CGX Is perfect for anyone who wants their mount to be versatile enough for portable setups and observatory use. This mount can accurately track with astrophotography systems up to 55 lbs, making it perfect for anyone wanting to upgrade to a larger OTA.

Key Features

Celestron CGX Belt Transfer

Heavy Duty Belt Transfer

A lot of mounts today use spur gears to transfer rotational motion from the motors to the worm wheels. The problem with spur gears is that there is an interment amount play between the teeth of the gears. This play introduces mechanical backlash and thus hinders tracking performance, especially when autoguiding. By using a belt transfer the backlash mentioned above virtually disappears and tracking accuracy is greatly improved.

Celestron CGX Internal Cabling

Internal Cabling

Cable management can get messy. Where some telescope mounts can get caught on their own cables and ruin a night of observing, the CGX avoids this entirely. The cables that connect the RA and Declination motor to the motor control are all wired inside of the mount.

In fact, if you wish to directly connect to the mount to a computer you no longer have to go through the hand controller. This mount has a USB 2.0 B type connector in the rear.

Celestron CGX Mechanical Hard Stops

Mechanical Hard Stops

the mechanical hard stop will prevent injury to you and/or your telescope. You will never have to worry about having your optical tube running into your tripod legs or swinging into the mount because of a loose clutch.

Celestron CGX Homing & Limit Sensors

Homing Sensors

Homing sensors in a mount is an awesome feature to have in an observatory setting. If power is lost throughout the night, you can "home" the mount and resync on the home position rather than creating an entirely new pointing model.

It also makes a great position to park the telescope after a night of imaging. The next night you want to observe turn the mount on and sync.

Celestron CGX Dual Saddle

Dual Dovetail Saddle

Swapping telescopes is now a breeze. Smaller telescopes often use the lighter less expensive Vixen style dovetail bar and Larger telescope often are equiped this the wider Losmandy style dovetail bar for it's sturdyness. The new Saddle on this mount clamps down on both types of dovetails.

The knobs also on this saddle have been improved to allow you really torque down on a dovetail bar without the use of special tools.

Celestron CGX Tripod

Improved Tripod

The Celestron tripod was completely redesigned. It has a wider stance that keeps a lower center of gravity to reduce vibrations. Each Leg has line-height markings which makes it quick and easy to set your tripod to the right height.

The Accessory tray has been redesigned as well. It was reshaped so it can now remain attached when the tripod is folded up. The tray now holds three 1.25" eyepieces, one 2" eyepiece, and one smartphone.

Celestron CGX Carry Handles

Ergonomic Carry Handles

Just look at that picture! Why can't every mount be that easy to carry? These handles really speed up the setup and breakdown times for an astronomer who is on the go. No longer will you have to awkwardly lug around the mount head or have trouble centering it over the top the tripod.

Celestron CGX Latitude Adjustment

All New Altitude Adjuster

Other EQ mounts, including the CGX's predecessor, the CGEM, are difficult and uncomfortable to polar align when a mounted telescope is mounted to it. Taking the telescope off the mount would be easier, but would give you a very inaccurate polar alignment once you put an OTA. Celestron addressed this by using an armature that rides on ACME threaded rod. This allows you to easily adjust the mount with one hand under load!

Celestron PWI Telescope Control Software

Celestron PWI Telescope Control Software

Celestron and Planewave Instruments have teamed up to develop a complete planetarium/mount control software. This program unleashes the full pointing accuracy potential of the CGX.

PWI employs PointXP mount modeling, which accepts numerous star alignment points for the best possible accuracy. PointXP (also used in StarSense AutoAlign accessory) goes beyond the pointing capability of a traditional hand control. By adding multiple star alignment points, PWI accounts for various types of alignment errors, including instrument flexure.

With a direct USB connection from your PC to the USB port on the mount, PWI’s Sky Viewer display makes for easy target selection or find your favorite deep sky object in PWI’s extensive object database.

Included Technology

All-Star Polar Alignment

Get ready for a night of astroimaging with your mount faster than previously thought possible with All-Star Polar Alignment. This innovative software solves the time-consuming problem of trying to pinpoint the North Celestial Pole.

Compatible Technology


The new Lithium Phosphate (LiFePO4) battery chemistry has significant advantages over other battery chemistries, great for those Astronomers on the go.

Starsense Technology

Celestron’s patented StarSense Technology makes it easier than ever to locate objects in the night sky, even if you’ve never used a telescope before. Turn it on and push ‘Align.’ In about three minutes, you’re ready to observe!


WiFi technology encircles the globe in a web of connectivity, knowledge, and information. Now, Celestron is using that same technology to allow stargazers to connect to the night sky and enhance their experience of the cosmos in fun and unique ways.

Ask a Question
  • I already own a celestron powertank lithium and a celestron skysync GPS accessory. Can these items be used on the CGX mount?

    Yes the Celestron Lithium Powertank and Skysync GPS will work on the CGX mount.

  • I already own a Celestron SKYSYNC GPS and a Celestron powertank lithium. Do these products work with this mount?

    Yes the Celestron SKYSYNC GPS and a Celestron powertank lithium with work with the CGX mount. 

  • What is the overall height of the mount itself from base to top of the saddle?

    On the CGX mount the height from the bottom of the base to the top of the saddle is 19".

  • How big are the shipping boxes for this mount?

    Here are the weights and dims for the two boxes: 24 x 21 x 15 @ 58# 47 x 13 x 13 @ 52#

  • Can the CGX mount polar align in the daytime using only the sun as a target rather than a single night time "star"? One of the five alignment methods is called "solar system". So again, can it use the sun as a solar system object to polar align? This woul

    The Celestron CGX does not have a built in polar bore so you may need to use the offset polar scope they have developed. However since the north star is not visible during the day a polar scope is of no use regardless. Normally poral alignment is acheived

  • You describe that the mount has re-designed mechanics. Does it mean the mount is refurbished?

    No, this mount has redesigned mechanics compared to the CGE mount it replaced. This listing is for a brand new mount and scope with a full warranty. Any refurbished or used products will be clearly marked as such on the website.

  • What are the diameters of the RA and Dec worm gears?

    Celestron just confirmed that the actual worm diameter is 14mm diameter with 18.5mm depth. The worm wheel gear measurements are in the previous answer.

  • What are the diameters of the RA and Dec worm gears?

    Celestron notes the worm wheel gear at 90mm in diameter for the CGX and 144mm for the CGX-L, but they do not note the specific diameter of the worm itself. They do note that the CGX and CGX-L use the same worm gear for both mounts. Please contact us if

  • Are the RA / DEC worm Gears Aluminum or Brass gears ? Does it have any permanently lubricated ball bearings ?

    According to Celestron: Spring-loaded brass worm wheel and stainless steel worm gear reduce friction and provide optimum gear mesh. The manufacturer does not make any statements as to the bearing type or lubrication.

  • Does the mount come with a counterweight?

    Yes, as in the picture the mount includes 2x 11 lb counterweights. If you need additional weights, you can add more of the CE-94286 weights: https://www.optcorp.com/celestron-advanced-vx-11-counterweight.html.

  • Is there any way to store a permanent PEC curve to the mount/controller?

    Yes all Celestron EQ mounts have the ability to do permanent Pec. You can download the Pec Tools program from Celestron's website to program your mount.

  • Does the CGX have an autoguider port?


  • Does this mount have what Orion calls "closed loop electronics," meaning when you disengage the clutches and point manually, the computer's digital setting circles still know where the scope is pointed?

    Unfortunately, no. The CGX does not have closed loop electronics.

  • Does this mount have what Orion calls "closed loop electronics"; when you loosen the clutches, point manually, and then re-engage the clutches/worm gears, does the computer know where you pointed?

    Unfortunately, no. The CGX needs to have the clutches engaged at all times after alignment to maintain position, as the mount does not have a second set of encoders to reference.

  • Hi. I was wondering whether you would ship this to Australia, given this is a second-hand unit and possibly not governed by Celestron's prohibitive sales 'rules'? Best wishes, Matt

    Used items do not fall under dealer shipping restrictions, so we can ship this telescope to Australia and most other countries. Please contact us if you have any questions.

  • What is the diameter of the counterweight bar? Does it take CGEM weights or CGEM DX weights?

    The diameter is 20mm. The CGX takes the same weights as the CGEM and AVX.

  • Will the Celestron C14 fit on the CGX mount? Cost of the CGX without tripod?

    Celestron states that the payload capacity of the CGX is 55 lbs. the weight of a 14" Edge HD is 46 lbs. This should work well just for visual use. If you plan on using this OTA for astrophotography, then bigger mount with a heavier payload is recommend.

  • Does the CGX mount support the Celestron C14 optical tube?

    Good afternoon, the Celestron CGX has a 55 pound capacity and will support the C14.
