Product Details


    Celestron's CGX-L Computerized German Equatorial Telescope Mount is designed for observatories and travel systems and is capable of carrying some of the largest telescopes with ease. The Mount Head only weighs 45 lb yet is able to support a 75 lb payload capacity.


    Key Features

    Celestron CGX-L Belt Transfer & Larger Worm Wheel

    Heavy-Duty Belt Transfer & Large Worm Wheels

    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 intermittent amount play between the teeth of the gears. This play introduces mechanical backlash and hinders tracking performance, especially when autoguiding. By using a belt transfer the backlash mentioned above virtually disappears and tracking accuracy is greatly improved.

    The CGX-L has large, brass, spring-loaded 144 mm diameter worm wheels to handle heavier loads and track more accurately. Together with the stainless steel worm gears, they provide excellent gear mesh and reduce friction.

    CGX-L Longer Dual Saddler

    Long Dual Saddle Dovetail

    Swapping telescopes is now a breeze. Smaller telescopes often use the lighter, less expensive Vixen-style dovetail bar. Larger telescopes are often equipped with the wider Losmandy-style dovetail bar for its sturdiness. The convenient saddle on this mount clamps down on both types of dovetails.

    The saddle on this mount has been elongated to 270 mm (approximately 11 inches) to better support larger optical tubes. This larger clamping surface area will reduce flexure and better stabilize a telescope.

    Built-in just below the dovetail saddle is two auxiliary ports and an autoguider port. This makes it easy to plug in extra accessories like the StarSense, WiFi module or ST-4 compatible autoguider. Since the cables for the port are run through the mount, you will no longer have to worry about cable snag.

    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 and uses massive 70 mm stainless steel tripod legs for improved stability under heavy loads. 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. It now holds three 1.25-inch eyepieces, two 2-inch eyepieces, and one smartphone/tablet in an upright position.

    Celestron CGX-L Carry Handles

    Ergonomic Carry Handles

    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 a tripod or pier.

    Celestron CGX-L Latitude Adjustment

    Altitude Adjuster

    Other EQ mounts 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 on 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 CGX-L Homing & Limit Sensors

    Homing Sensors

    Homing sensors are an awesome feature to have in an observatory setting. If power is lost throughout the night you can "home" the mount and resync on that 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, just turn the mount on and sync.

    Celestron CGX-L 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-L 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 on the rear.

    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-L.

    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.

CGXL the ultimate mount?

I've run a CGE mount for 15 years pushing the load limits, held out as mounts come and go, and then the CGXL came out, heard a lot of good things about it, time to step it up. WOW! Last night I rough aligned towards North and set altitude using the gauge on the mount nothing fancy, performed a two-star alignment, the moon was super bright it was late done for the night. Today I used 'last alignment' to see if I could find any planets during the day. I was stunned to see Mercury, Venus, and Sirius slewed almost directly centered in the eyepiece first time! Amazing! This mount far exceeds expectations ! The feel, the sound, 'Go to' accurate tracking everything about this mount is all business, looking forward to imaging stay tuned for an update. Note: If you have an observatory you will need an adapter plate to attach the mount to the pier, should be mentioned if purchasing w/out the tripod? The 110-volt power supply does not come with it. The manual is a PDF file, would prefer a hard copy. Cheers!

Dead on tracking and pointing.

Easy to use and VERY accurate. Manual, precise polar alignment doesn't really take that long and with a high power reticle eyepiece very accurate. Doing high power solar and lunar I can walk away for half an hour and its still right on feature I was observing. I'm sure it would require little or no adjustment after an hour. Every thing high quality. Well worth the wait the recent wait.. I have two. One for 6" refractor and one for 14" SCT. Strongly recommend GPS unit. Adds significantly to accuracy and makes startup fast. Also dead centers Mercury, Jupiter and Saturn after sunrise and midday.

CGX-L first test.

So far I love it. No backlash! It works well with the external GPS and star sync. It would be nice if they built in a USB hub. It would also be nice if it had a built in GPS. Having the power and hand pad plug in stationary was a huge improvement. Shipping by OPT was fast.

Blows my AVX away, but its supposed to.

Have not had much use of it (cgx-l) yet, but have it up and running, and the few times I have used it, are amazing to say the least. Glad I sprung for the (-L) rather than just the cgx. The tracking is excellent, so far for observing, have not hooked up either of my cameras yet. Can't find my guide camera. So relying only on Telrad ATM. Will need to update this, but so far well worth it for the EdgeHD11". Did get a motorized focus, and that thing is AWESOME, but for another review/feedback.

My God look at all the stars

Theirs nothing but good things to say about this mount. Read most reviews and You Tube most owners are very pleased as I. I do own the CGEM-DX what very sturdy but my C14 with accessory is pushing it. The new mount no problem.The only thing to get use to is the polar scope if you decide you go that route. The hand control cable like all Celestron scope is a bit short you can purchase a extension cord from scope stuff. And last not one but at lease two counter weight. The reason you buy a heavy duty mount is to put a heavy load on it. Or maybe and option to get a few accessories maybe at a slight discount.

Easy, ergonomic adjustments

Very sturdy construction. Large, well placed knobs for easy adjustments. NexStar+ HC easy to learn with lots of navigation options.
