Celestron 11" EdgeHD SCT OTA
on CGX-L Computerized Equatorial Mount

This Celestron 1100 EdgeHD CGX-L Telescope package is a dream come true! The Celestron CGX-L 11" EdgeHD optical tube assembly is perfect for visual or imaging, and its aberration-free optics produces a flat field with beautifully round stars from edge to edge, whether you are using one of today's wide field eyepieces, a DSLR, or a dedicated CCD camera. For a spectacular telescope such as this, you'll want an equally spectacular mount, and you can't go wrong with the Celestron CGX-L! This newly designed computerized equatorial mount will hold 75 pounds of equipment with ease, and still point and track with extreme accuracy. Features like software-assisted polar alignment, multi-point modeling, plate solving, a spring-loaded worm drive, four AUX ports for plug-in accessories, two AutoGuider ports, home and limit sensors, and more make the Celestron CGX-L a superb mount, and its completely redesigned tripod, with its wide stance and 2.75" diameter legs, will support your telescope and mount with ease.

Features of the 11" Celestron 1100 EdgeHD OTA

  • The Celestron 1100 EdgeHD OTA has 11" aplanatic SCT optics that produce an aberration-free flat field from edge to edge, whether you are using a wide angle eyepiece, a DSLR, or a dedicated imaging camera

  • Truly diffraction limited stars are beautiful to behold as pinpoints in a velvety dark celestial landscape

  • Flexible tension clutches keep the mirror in place to reduce image shift as you work through the night

  • Tube vents help the primary mirror cool down faster, and has an integrated 95 micron mesh filter to keep dust out of the system

  • Install the optional focal reducer to convert your f/10 system to a wider, faster f/7.

  • The Celestron 11" EdgeHD is Fastar compatible, allowing you to remove the secondary mirror and install a third party lens assembly (sold separately) for amazingly fast f/2 wide field imaging. With Fastar installed, you can reduce exposure times significantly and enjoy a field of view that is five times wider than at f/10.

The Celestron CGX-L 11" EdgeHD is one of the most versatile imaging telescopes on the market. At its native f/10, you can achieve the image scale necessary to capture the smallest of deep sky objects. Add the optional reducer lens, custom designed for the 11" EdgeHD OTA, and you can increase your field of view without sacrificing optical performance. By adding an optional Barlow lens, you will have added power for high-resolution planetary, lunar and solar imaging. Finally, the 1100 EdgeHD optical tube (like all EdgeHD OTA's) is 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.

Features of the Celestron CGX-L Mount

  • The CGX-L has larger, 144 mm diameter worm wheels to handle heavier loads and drive them accurately. The worm wheel is made of brass and is spring-loaded, and together with the stainless steel worm gear, they provide excellent gear mesh and reduce friction, creating a buttery smooth belt drive system.

  • The right ascension and declination motors used on the Celestron CGX-L have more torque for improved tracking and slewing under load. Working together with the belt drive system, you’ll experience minimal backlash and worry-free operation. You can even watch the pulleys and belts working through the motor cover windows!

  • Celestron has increased the number of auxiliary ports to four (4), and has even added an additional autoguider port so that you have maximum flexibility when it comes to electronic accessories. Two of the AUX ports and an Autoguider port are built in just below the dovetail saddle, making it easy to plug in extra accessories like the StarSense or WiFi module and not worry about the cord causing a problem as the mount moves. Speaking of cabling, those required to run the mount are run internally, so even if you are running your CGX-L remotely, you don’t have to worry about cable snags.

  • Mechanical hard stops and limit sensors on both axes protect the Celestron CGX-L from hitting the tripod or causing undue stress on the cables. Built-in limit sensors will actually stop the mount from slewing or tracking further before the CGX-L reaches the hard stop fail safe.

  • Home sensors are built into the CGX-L mount, making it a great choice for remote use. Now you can always start your mount from the same index position, regardless of where it was pointed when the mount was last used.

  • Celestron’s PWI software was co-designed by Planewave Instruments, a company famous for their professional-level telescopes and mounts. One of the features of this software is multi-point mount modeling, which is normally only included with mounts costing thousands more. Multi-point mount modeling allows you to increase the pointing accuracy of the CGX-L mount. The software also includes plate solving and focus support.

  • With all the features of the CGX-L, it is easy for overlook the fact that this is a computerized mount. The included Celestron NexStar + hand controller has a USB port on the bottom to make updates easier. It includes a bright, easy to read LCD display, a 40,000 object database, and a variety of choices in the software to make finding and observing celestial objects a breeze.

  • The CGX-L has redesigned and ergonomic adjustment knobs throughout. These knobs are large and easy to turn due to reduced friction, even under heavy loads.

  • With the CGX-L, you don’t need a separate finder, application, or other alignment accessories to do an accurate polar alignment. Software Polar Align is a feature that allows you to do an “All-Star Polar Alignment” on any bright star quickly and accurately. If you would like to use a polar scope to align in the classic manner, Celestron has designed one specifically for the CGX or CGX-L Mount. See the recommended accessories for a link to the product.

  • Dual Dovetail Saddle with extra length. The beefy dovetail saddle on the CGX-L is the ultimate in flexibility. It is 270 mm (almost 11”) long, and accepts either a Vixen-style (CG-5) dovetail plate or the wider Losmandy-style (CGE) plate. This means you can mount just about any telescope on the CGX-L quickly and easily, making it a very flexible mount.

  • Now let’s talk about the CGX-L’s excellent load capacity to mount weight ratio. The weight capacity of the CGX-L is 75 pounds, however, the mount head only weighs an amazing 52.6 pounds. While not light as a feather, that means this very capable equatorial mount is still considered portable. Celestron has created a very ergonomic design that makes it easier to carry and set up. There are handles built in so you can carry close to your body (see extra images for an example).

  • The CGX-L Tripod has been completely redesigned to handle the extra capacity of the CGX-L mount. It’s large 2.75” diameter legs spread wider than usual for added stability, and the height is adjustable from 35.75” to 52.75”. A heavy-duty accessory tray holds three 1.25” eyepieces, two 2” eyepieces, and even has a shelf built in to hold your smartphone or tablet in an upright position! It can stay in place even when the tripod is collapsed, making it much easier to set up, break down, and store your tripod.

  • The Celestron CGXL comes with a larger 31.5mm diameter counterweight shaft to support the required counterweights needed to balance your OTA and accessories. The mount comes with two 22-lb. counterweights, and of course more are available separately. You will also receive a Celestron DC Power Cable to run the mount. It plugs into a cigarette lighter socket, which means you can run the CGX-L from your car battery, or you can use a portable DC battery like the Celestron PowerTank Lithium (sold separately). An AC Adapter is also available should you prefer to run your mount from household current.
