The Celestron AVX11SC Advanced Series computerized go-to XLT multicoated Schmidt-Cassegrain has the most advanced optical multicoatings package available in its aperture and price range. It has a light grasp 1593 times that of even the sharpest dark-adapted eye. With that much light-gathering power, the AVX11SC can reveal to you star clusters, nebulas, planets, and galaxies in amazing and intricate detail. The new Advanced VX Series go-to mount makes finding over 40,000 of those objects easy and automatic, so you can spend your time looking at them, not looking for them.

For the ultimate in optical performance from a scope of its aperture, it has special Starbright XLT full multicoatings that are 16% brighter than even the legendary Celestron Starbright multicoatings - long considered to be the industry standard. The optical tube is a larger version of the Celestron-pioneered optical system that took phenomenally expensive Schmidt-Cassegrain optics out of the hands of professional astronomers and made them available for the first time at a reasonable price to all amateur astronomers. In essence, the original Celestron 8" SCT made modern amateur astronomy possible.

And now, the 11" AVX11SC Advanced VX go-to is priced to make high resolution big aperture automatic astronomy available to almost everyone. Its light weight optical tube and easily assembled mount make it easy to set up and enjoy - either in your back yard or at a distant dark sky site. Superb optical quality, a solid and accurate mount, and a very reasonable price make it a scope that many beginning and advanced astronomers can afford and enjoy.

This Telescope's Optical System . . .

Schmidt-Cassegrain optical tube: 11" aperture (2800mm focal length f/10). Guaranteed diffraction-limited optical performance. High light transmission Starbright XLT multicoatings. The 11" aperture gathers 21% more light than a 10" telescope and almost twice that of an 8" scope, providing bright images of faint deep space objects. The 11" aperture also provides a very sharp 0.42 arc second resolution, to resolve star clusters and show lunar and planetary features is sharp detail. The 24" long aluminum optical tube weighs only 26 pounds, making it easy to transport and assemble in the field. There is a handle on the rear of the tube for easier carrying and positioning of the optical tube.

Finderscope: 9 x 50mm straight-through achromatic design, with a wide 5.8 degree field of view.

Visual back: Removable 1.25" visual back holds visual accessories such as star diagonal, tele-extender, etc.

Star diagonal: 1.25" prism type.

Eyepiece: 1.25" 40mm Plössl (70x). The eyepiece field of view is 0.61°, 20% wider than the full moon.

This Telescope's Mount . . .

Heavy duty Advanced VX Series computerized go-to German equatorial mount: This scope's new Advanced VX mount was specifically designed to provide optimum imaging performance for telescopes 30 lbs and under. It has the imaging-friendly features of Celestron's larger telescope mounts, such as permanent periodic error correction (PPEC) and the ability to image across the meridian without doing a meridian flip, so you can seamlessly image the best part of the night sky.

Experienced imagers will love taking this portable mount to a dark sky site (the head weighs only 26 lbs, the tripod only 18 lbs, plus two 12 lb counterweights), as it provides all the performance of their larger observatory mounts in a portable package. If you're new to imaging, the Advanced VX mount will help you get started with the hobby and keep up with your needs for years to come.

The mount includes dual-axis slewing/tracking low-cog DC servo motors with positioning encoders on each axis for go-to computer control. The new motors provide improved tracking performance and more power to handle an unbalanced load than previous Advanced Series drives. Built-in adjustable backlash compensation and permanent user-programmed periodic error correction (PPEC) permits precise corrections during astrophotography and when observing visually at high powers. The maximum slewing speed is a fast 4° per second.

The scope is supplied with a car battery cord to operate from the cigarette lighter plug of your car or from a rechargeable 12V battery pack. The mount requires a 12VDC 3.5A power source, so the Celestron 17 amp hour capacity Power Tank #4517V is recommended for extended use in the field. The Power Tank can be recharged hundreds of times and will operate the scope all night long without danger of running out of power. Celestron AC adapter #2338PRO is also available to operate the scope from household AC in your back yard.

The two sliding 12 pound counterweights are locked in place with a single hand-tighten thumbscrew each, making it easy to rebalance the scope if you add heavy photographic accessories. The mount is easily capable of handling the scope and any reasonable combination of photographic accessories you might want to use. Snap-on covers keep the motor drives free from dust and debris. A set of optional vibration suppression pads #4525 under the tripod feet will improve the telescope damping time for steadier high power observing.

To make a casual polar alignment for visual use quick and easy, there's a latitude scale and fine adjustment controls in both altitude and azimuth. The scope can be used over a wide 7° to 77° latitude range in both the northern and southern hemispheres. The scope includes Celestron's unique All-Star computerized polar alignment that lets you do an accurate polar alignment even when Polaris is hidden by trees or buildings.

Adjustable height tripod: The tripod has 2" diameter steel legs with a center leg brace for rigidity, with excellent damping characteristics. The center leg brace is drilled to form a convenient accessory tray that holds 1.25" and 2" eyepiece to keep them up out of the dew-soaked grass.

Dovetail slide bar: An adjustable Vixen-style dovetail slide bar allows the optical tube to be quickly and precisely balanced fore and aft on the mount, eliminating the need for an extra counterweight to balance a camera or other accessories. Setup and takedown times are exceptionally fast, as a single large hand-tighten knob holds the optical tube in place. A second lock knob prevents the tube from sliding off the mount should the hand-tighten knob loosen. The Vixen-style dovetail on the mount allows you to use other optical tubes on the Advanced VX mount, adding to the scope's versatility.

NexStar+ computer hand control: The supplied NexStar+ computerized hand control has a built-in database of more than 40,000 stars and deep space/solar system objects it can find for you. These include the complete RNGC, Messier, Caldwell, IC, and Abell catalogs; selected SAO stars, such as variables and multiple star systems; the planets, the Moon, and more. There is enhanced information on over 200 of the most note-worthy objects.

You can also store and edit the right ascension and declination of additional user-defined objects of your own choosing, such as the comet and asteroid coordinates published monthly in Astronomy and Sky & Telescope magazines. The computer control can find any of those objects with at your command, and accurately track them for visual or photographic application.

All of the database and telescope operation information is displayed on a double line, 16-character, liquid crystal display on the hand control, which has user-selectable multiple language display (English, French, Italian, German, and Spanish). There are 19 fiber optic back-lit LED buttons to make it easy for you to control the computer without affecting your dark adapted vision. An RS-232 communication port on the hand control allows you to operate the telescope via a personal computer. The computer hand control software can be upgraded over the Internet from Celestron's website, assuring that you always have the most current software version at your command.

Several different alignment methods are built into the NexStar+ computer, allowing you to choose a level of computer accuracy in automatically finding objects with which you are comfortable. Both two-star and more-accurate three-star computer guided alignment methods are easily accomplished in only a few short minutes. You can be observing in less than 15 minutes after you first take your scope outdoors, including telescope assembly time.

In addition, the NexStar+ computer hand control is GPS-compatible (using an optional inexpensive SkySync GPS module) for full GPS (Global Positioning System) satellite accuracy. Adding GPS to the computer is something no competitive scope can do. With the Advanced Series go-to mount and the SkySync, orienting the scope in time and space on earth and aligning the scope on the sky becomes almost as easy as simply turning the scope on.

Two-year warranty: All Celestron go-to telescopes have a two-year warranty.

I own the C-11 and Advanced VX mount combination. The C-11 is a great optical tube, and great for planetary viewing and globular clusters. In terms of magnification and clarity for planetary viewing, it is a very obvious improvement over the C-8. For nebula and galaxies, getting to a dark site would be recommended. Planetary video photography via the C-11 and VX mount also works well. For long exposure photography though, the C-11 optical tube is too heavy for the VX mount, in that any touch or vibration, such as wind, is not adequately damped by the mount. A great starting point though for a large aperture telescope! (Posted on 9/9/2019)

I own the same C11 OTA. The huge aperture provides crisp, bright views. M13 looks incredible through this scope, and the long focal length makes for great planetary viewing and imaging. I've had moderate success imaging DSOs with this scope, but it's better suited for lunar and planetary imaging. All in all, it's a fun scope to own and will really wow your friends ar star parties.

I have used this at my local star party in Naperville IL. Due to its long focal length and weight this is mainly a visual telescope. I took images of planets and they look amazing, but when taking images of deep sky objects the only "good" object I could end up getting was the Orion nebula. Once again this is a great telescope for the visual use of seeing galaxies, nebulas and more but not for images deep sky objects. (Posted on 12/21/2018)
