The Celestron 11-Inch CPC Schmidt-Cassegrain with StarBright XLT Coatings offers innovative technology that will allow you to look deep into space. This scope combines new SkyAlign alignment technology, advanced engineering, and a bold new design, all at an affordable price.
In fact, Celestron's Professional Computerized (CPC) Series with revolutionary SkyAlign alignment technology redefines everything that amateur astronomers are seeking. They offer quick and simple alignment, GPS, unsurpassed optical quality, ease of setup and use, advanced ergonomics, enhanced computerization, and value for money. The 11-inch CPC truly has it all.
The Celestron CPC Series includes an internal GPS receiver that automatically downloads the date and time from orbiting satellites, pinpointing the telescope's precise location. This eliminates the need for you to input the date, time, longitude, and latitude manually.
Thanks to SkyAlign, alignment is a breeze. Simply locate and manually point the telescope towards three bright celestial objects - even the moon and bright planets will work. Celestron's NexStar software technology will then model the night sky to determine the position of every star, planet, and celestial object above the horizon.
Once aligned, the remote hand control allows direct access to each of the celestial catalogs in its remarkably user-friendly database. The CPC's database contains more than 40,000 celestial objects, including the Caldwell Catalog, as well as NGC Galaxies, nebulae, and planets. User-definable filter limits make navigating through this expansive database quicker and easier. When using the "filter limits" feature, only those objects that are above the horizon at your exact time, date, and location will be displayed.
The new CPC Series telescopes feature meticulously matched and hand-figured optical systems manufactured in Celestron's facilities in Torrance, California. In addition, the CPC is available with StarBright XLT high-performance optical coatings. These use state-of-the-art, thin-film, vacuum-deposition technology. To ensure consistent optical coatings of the highest quality, the process is tightly monitored and controlled by highly trained technicians. The result is image clarity so stunning it must be seen to be believed.
This telescope includes the NexRemote software, enabling you to operate it remotely from a PC or laptop. NexRemote supplicates all of the functions and features of the NexStar software on the standard NexStar Hand Control. It also offers speech support, allows you to create and save custom tours, and uses Night Vision Mode to preserve night vision. The drive base and mechanics have been redesigned with larger gears and a quick-release clutch.

Powering your Celestron CPC Telescope
The Celestron CPC Series Telescopes include a DC power cable, the kind you can plug into a automobile cigarette lighter. The CPC series telescopes do not take batteries. Won't take batteries! What! Actually this is a good thing. These larger telescopes eat through batteries pretty quickly. Its best to have a more reliable power source. A Celestron PowerTank is great for traveling to darker sky locations.
Astrophotography with the Celestron CPC Telescopes
While astrophotography could not be summed up here in one paragraph, a very common question for the CPC telescopes is how to connect a camera to it. Astrophotography is a hobby of patience and lots of trial and error, and plenty of errors will be had once you get started. But the rewards of good images is well worth it.
Available Recommended Accessories
The Celestron CPC Telescopes have many enhancement accessories available.
The 11 Inch CPC Telescope includes a 40mm Plossl Eyepiece. The 11 Inch CPC focal length is 2800mm so this included eyepiece will yield you 70x magnification. To get the most from your new CPC Telescope, we recommend you have a wide selection of eyepieces for high power viewing as well as wide-field viewing.

- 6mm (467x Magnification)
- 9mm (311x Magnification)
- 15mm (187x Magnification)
- 32mm (88x Magnification)
This wider array of eyepieces will enhance your viewing of lunar and planetary surfaces. Select the Celestron Eyepiece and Filter Kit - 1.25 Inch Format as a great starter accessory for getting the most of your new Celestron 11 Inch CPC Telescope.
Upgrade to a 2 Inch Diagonal and 2 Inch format Eyepieces
2 Inch Format Eyepieces will deliver a wider field of view. Instead of only having the Andromeda Galaxy in your field of view, now you can also have the same view but with its surroundings. A 2-Inch format eyepiece also gives the feeling of "spacewalking" into the view. Your eyes see substantially more field of view and many find that the 2 inch format eyepieces are more comfortable to view into.
Before you can use a 2 inch format eyepiece on the 11 inch CPC telescope, you must upgrade the 1.25 inch format diagonal that is included with the telescope. By changing to a larger 2 inch format diagonal you are now able to use 2 inch format eyepieces. Most 2 inch format diagonals also include a "reducer" adapter that will continue to allow you to use your 1.25 inch format eyepieces.
Here are some choices of upgrades to change your 11 Inch CPC Telescope to use 2 Inch Format Eyepieces:
Upgraded Diagonal, now select some premium 2 inch format eyepieces
Its common to hear that your telescope is only as good as your eyepiece. The eyepiece is how you deliver the image your telescope has gathered to your eye. A quality eyepiece can mean the difference of seeing major amounts of detail. Here are some favorite choices for 2 Inch format eyepieces:
Power Adapters and Power Sources
The Celestron CPC telescopes include a car battery adapter power cord for powering your telescope through your vehicle.

Ready For Astrophotography?
The rewards of capturing images from space are endless - so are the accessories and techniques for doing it! The Celestron CPC telescopes are an amazing tool for astrophotography. While we are not going into long detail of astrophotography technique, we will cover here what accessories are used for astrophotography with the CPC series telescopes. There are different methods of mating your particular camera to the CPC, or other choices of astrophotography tools you should know about:
DSLR Imaging - One of the fastest growing and most popular methods of astrophotography is using DSLR Cameras. The most popular digital SLR cameras are from Nikon and Canon. To connect a DSLR camera to your CPC telescope, you will need 2 pieces - A T-Adapter and a T-Ring.
To connect your DSLR camera you will need to remove the lens from the camera, and replace it with a T-Ring. With the appropriate T-Ring attached to your DSLR camera you will then be able to connect your camera body directly to the T-Adapter connected to your CPC telescope.
Preventing Dew with the 11 Inch CPC Telescope
Dew forming on the lens of your telescope can quickly end an evening of observing. Once dew has formed, its very difficult to get rid of it. The answer is to prevent it from happening at all. Dew prevention can mean taking full advantage of those rare clear sky evenings or packing it in early.
There are two methods of preventing dew from forming. Dew Shields and Dew Heaters.
About Celestron Schmidt-Cassegrain Telescopes
Celestron’s excellent Schmidt-Cassegrain telescopes are compact and portable and represent the best all-purpose design for a wide variety of uses from terrestrial and deep sky viewing to astrophotography.
Catadioptrics use a combination of mirrors and lenses to "fold" (reflect) the light path and form an image. In a Schmidt-Cassegrain, the light enters through a thin aspheric Schmidt correcting lens. It then strikes the spherical primary mirror. It is reflected back up the tube and intercepted by a small secondary mirror which reflects the light out an opening in the rear of the instrument where the image is formed at the eyepiece.
Catadioptrics are the most popular and most modern type of telescope optical design and are marketed throughout the world in 3.5" and larger apertures. Catadioptric telescopes combine the practical advantages of lenses and mirrors while eliminating their disadvantages. They offer the clarity and contrast of refractors with the low aberration of reflectors. Catadioptrics have an average focal ratio of f/10, which is wide enough for all types of photography. They are also easier to maintain because all optical elements are solidly mounted and rigidly collimated. Catadioptric telescopes provide the best possible combination of light gathering power, long focal length, portability and affordability.
