    Celestron CPC 1100 XLT 11 Inch Schmidt-Cassegrain Telescope

    With the largest aperture of the Celestron CPC GPS line, the CPC 1100 GPS Schmidt-Cassegrain telescope delivers the most light gathering power and a limiting magnitude of nearly 15. The CPC 1100 GPS takes full advantage of its vast database of thousands of NGC and Abell galaxies and provides a new level of detail to all your favorite deep sky objects.

    Celestron CPC Telescopes are available in three aperture size choices:
  • 8 Inch CPC Schmidt-Cassegrain Telescope
  • 9.25 Inch CPC Schmidt-Cassegrain Telescope
  • 11 Inch CPC Schmidt-Cassegrain Telescope

  • Incredible Aperture Size and Clarity

    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.

    Computerized Convenience

    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 Messier objects, 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. It includes a new heavy-duty steel tripod with accessory tray and center leg support bracket to ensure stability.

    Excellent! - Review by
    Overall Score
    I am only a novice but didn't have any problems setting up to view within about 3 or 4 minutes. It is a bulky and weighty scope but still easy to manage onto the great tripod supplied. You must accept a bit of weight to get the excellent views the 11 inches gives. I have since purchased a further set of lenses and a T-ring and adapter so I am set to produce some stunning photos. I have nothing but praise for this excellent scope and recommend it for anyone.

    CPC 1100 - Review by
    Overall Score
    For the price,being only $700 more than the CPC 9.25,the CPC 1100 was well worth buying.Alot longer focal length,and bigger aperture captures more detail, and higher magnification can be used.Lifting the scope onto the tripod is easy ,as it is only at waist height.The finder took a fair bit of fiddling to center with the eyepiece,goto and tracking are excellent.The GPS will show GPS LINKED once it has finished, only about 3 minutes and its ready to align,using the different alignment methods.I have added a losmandy dovetail and 1 kg counterweight to the bottom of the scope,as l am using a crayford 2 inch 10 to 1 focuserand 2 inch quartz star diaganol.The 1.25 visual back and 1.25 diaganol can be used without the dovetail and counterweight,they are supplied with the scope.I do recommend this scope,its also fastar compatible,and yields bright crisp views.

    Is a larger telescope available (larger than the 11 inch) for sale? Can you provide details please.
    The CPC 1100 is the biggest cassegrain telescope we have listed on our website, but we can get bigger scopes in from our supplier. (We do offer 12" configurations of dobsonian telescopes which can be found on our website here: http://www.ozscopes.com.au/telescope/dobsonian-telescope). We can offer up the 14" apertures for cassegrain telescopes. If you are interested, we can get the Celestron CGEM Pro 1400 into stock for you. This is a 14" telescope and will give you 60-70% more light gathering capacity when compared to an 11" aperture. Pricing for this scope would be around the $15,000 -$16,000 mark. We can also offer the Celestron CGEM PRO 1400 Faststar which has additional lens coatings which is about $200 more than the standard model. Details can be found on the Celestron website here: http://www.celestron.com/c3/product.php?ProdID=554 The CGE Pro 1400 HD is another 14" telescope we could source for you. You can find details of it on the celestron site here: http://www.celestron.com/c3/product.php?ProdID=553 We can also offer the Edge HD 1400 Optical Tube Assembly. Pricing would be around the $20,000 mark just for the tube. You would need to buy a mount in addition to this. You can find information for this on the Celestron site here: http://www.celestron.com/c3/product.php?CatID=17&ProdID=583
