Product Details


    The Celestron CGX Computerized German Equatorial Telescope Mount is designed to better support your telescope for both visual observing and astro-imaging. This mount can accurately track with astrophotography systems of up to 55 pounds, making it a perfect upgrade to a larger OTA!

    Optimize your Equipment with the Celestron CGX Computerized EQ Mount

    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 internment 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, backlash 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.

    Directly connect the mount to a computer with its USB 2.0 B-type located on 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 re-sync 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 V-style dovetail bar and the Larger telescope is often equipped with the wider Losmandy style dovetail bar for its sturdiness. 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 to 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-inch eyepieces, one 2-inch 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 of 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 on it. 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.

    PlaneWave employs PointXP mount modeling, which accepts numerous star alignment points for the best possible accuracy. PointXP (also used in the StarSense AutoAlign accessory) goes beyond the pointing capability of 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 finding your favorite deep-sky object in PWI’s extensive object database.

Great Mount but Beware !

In every way but one, this is a great mount. Unfortunately in my hands, it has a fatal flaw which, fortunately, is easily correctable. The problem is that I am simply unable to tighten the locking levers for the tripod legs enough so that they do not slip. I almost had a catastrophe with my 9.25 Edge HD when one leg started slipping, and the entire unit started to tilt. Fortunately, this happened slowly enough so that I was able to catch it and prevent everything from falling and ruining my telescope and possibly the mount itself. I am not sure if I received a defective mount, or if this is a basic design flaw, but just looking at the small diameter locking screws, which are uncomfortable to tighten (they need a round knob design) does not give one confidence that they might not slip at some point, especially when extra accessories are mounted. Obviously, failure of any one of the legs would result in a very expensive event. I did not try to use pliers to tighten, as I did not want to dimple the leg shaft. I am actually amazed that Celestron skimped on the one point of failure that could ruin an entire set up. If this was a defective blender that I could have easily packed up and returned, I would have, but obviously returning such a heavy mount is impractical. So, after a lot of thought and research I found a very simple and low cost solution. I ordered three stainless steel split clamping collars 1-1/2" Bore Size, 2-3/8" OD, with 1/4-28 x 3/4 set screw. They come in regular steel for 1/3 of the cost of the stainless steel ones, but I did not want to have to worry about rusting. These tighten around the entire circumference of each leg, and I am quite confident that no slipping or failure will occur. I really hope Celestron totally rethinks the design of what is obviously a critical, and single point of failure ,part of this mount.

A weighty review.

What can I say about a counter weight? It is doing what it was ment to do. Delivery was fast and in a timely manner.

Definitely an Upgrade Over the AVX and SVP

As others have expressed, the CGX is most definitely an upgrade over the aforementioned mounts. With minimal PHD 2 tweaks I'm able to get decent guiding in all directions - and I'm still learning. With the AVX I could get good guiding only when pointed to the NE. The mount is about 2 1/2 times more heavy thus better stability. I use StarSense for auto-align (I'm lazy!) and was able to score an add on attachment allowing me to use my QHY PoleMaster w/o removing the forward handle. All in all I'm really enjoying this mount. My only con (4 stars) is that like my other Celestron mount it's somewhat stiff in Dec and RA - something I'll likely remedy with a hypertune service later. Whenever these are available again I highly recommend you grab one.

Very Surprised

I was not expecting it until the end of January due to COVID slowing down or outright stopping supply chain activity. Actually received it before xmas! Also received the equatorial mount early, also slumbering in its shipping crate. I have not opened either box yet, as they are most safe where they are. Should probably open, inspect and re-seal both. Will be happy to review both when my concrete slab is poured, observatory (SKYSHED) is assembled, and we get to polar alignment, First Light, etc.

The price has gone thru the roof

What is being bought as an ota today, I received a cgem mount and ota for the same price in 2016
