Product Details

  • The Celestron 11-inch EdgeHD CGX Telescope combines Celestron's all-new CGX computerized equatorial mount with its acclaimed EdgeHD optical system. Key designs include a lower profile EQ head, which provides a more compact and stable setup, a better drive system, remote operation-friendly with home and limit optical sensors, easier polar alignment adjustments, and better cable management.

    With an optical tube assembly weighing only 28 lb, it's still portable enough to be taken to dark skies and has 89% more light-gathering power than an 8-inch telescope and 40% more than the 9.25-inch!

    For astrophotography, the CGX mount offers a sturdier, stouter platform, with a smoother, heavy-duty belt drive system, new electronic and ergonomic features that favor worry-free remote operation, plus all-new advanced software.

    Experience the Specialized Features of the Celestron 11-inch EdgeHD CGX Telescope


    • See pinpoint stars all the way to the edge with EdgeHD’s flat-field and coma-free optics!
    • Its aluminum optical tube with tube vents feature an integrated 95-micron mesh filter that allows hot air to be released from behind the primary mirror. Mirror support knobs hold the mirror in place and reduce image shift during imaging.
    • 3 focal ratios: Native f/10, f/7 with the addition of a focal reducer, or ultra-fast f/2 imaging with a removable secondary mirror and third-party accessories.
    • With Celestron's StarBright XLT optical coatings on every surface, EdgeHD optics gives you maximum light throughput across the widest visual and photographic spectrum.


    • Sturdier and more rigid with quicker dampening time.
    • Increased load capacity to 55-pounds.
    • 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.
    • Spring-loaded brass worm wheel and stainless steel worm gear reduce friction and provide optimum gear mesh.
    • Internal cabling provides worry-free remote operation. Power input and 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 provide 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.
    • Software includes multi-point mount modeling for precise pointing accuracy and many more additional features for remote astro-imaging.
    • Wider tripod stance for improved stability.
    • Adjustable EQ head position to optimize center of gravity over the tripod and fully utilize the increased 3-degree to 65-degree latitude range.
    • Dual-fit CG-5/Vixen and CGE/Losmandy dovetail saddle.


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


    • Two handles for easy pickup and transport.
    • All-new ergonomically designed dovetail clamping knobs.
    • Innovative and improved polar alignment adjustment system.
    • All-new ergonomic latitude adjuster for smooth and easy adjustment under full loads.


    • All-new NexStar+ hand control with USB port.
    • Two AUX accessory ports to support wireless/WiFi alignment and operation with StarSense AutoAlign and SkyPortal WiFi Module accessories (sold separately).
    • USB 2.0 port, used to connect directly to PC with included software.
    • Autoguider port.
    • PPEC ready.
    • Threaded 12V DC power input barrel connector.
    • Internal Real Time Clock (keeps time and site information saved).


    • Flexible tension clutches hold the mirror in place and reduce image shift when taking long-exposure astro-images. 
    • Each cooling vent has an integrated 95-micron micromesh filter guaranteed to let warm air out without letting in dust.
    • A Barlow gives you added power for high-resolution planetary, lunar and solar imaging. All EdgeHD optical tubes are Fastar-compatible, allowing the secondary mirror to be removed and replaced with a third party lens accessory for ultra-fast f/2 wide-field imaging. 


    • Its EdgeHD optics produce a focal plane more than three-times flatter than a standard Schmidt-Cassegrain telescope! Get visibly sharper stars on even the largest CCD chips every time! Learn more about EdgeHD technology.

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
