About the Celestron CGE Pro 1100 - 11" SCT with Computerized Equatorial Mount...

The CGE Pro 1100 Schmidt-Cassegrain Celestron Telescope is part of Celestron'''s "Top-of-the-Line" German Equatorial mounted astronomical telescopes. With the optical tube assembly of the CGE Pro 1100 weighing only 27.5 lb., the Celestron CGE Pro 1100 Telescope is still portable enough to be taken to dark skies, and it has 89% more light gathering power than an 8" telescope and more than 40% more than the 9.25".


As a visual instrument, you can search for all of the Messier Catalog objects, and you can see hundreds of other equally interesting NGC, IC and Caldwell objects. Turn the Celestron CGE Pro Telescope to the planets and see amazing detail on the surface of Jupiter; see Cassini''s Division in the rings of Saturn, and resolve details on the surface of Mars. Even the distant Uranus, Neptune and Pluto are within your Celestron Telescope'''s reach.


In addition to being fully computerized with a database of over 40,000 celestial objects, the CGE Pro German Equatorial mount has been completely redesigned to offer numerous Celestron Telescope Mount design advantages:


Increased Payload Capacity - With a maximum payload of 90 lbs, the CGE Pro mount is able to hold the telescope more securely even when fully loaded with all your imaging gear like a Celestron CCD Camera.


All-Star Polar Alignment - Choose any bright alignment star for a software assisted alignment of the Celestron Telescope Mount'''s polar axis that will have you ready for imaging even if you can''t see the North Star.


No-Tool Polar Alignment - Larger hand knobs for both Altitude and Azimuth adjustments.


Meridian Tracking - Extended tracking past the Meridian of up to 20 degrees of uninterrupted imaging through the best part of the sky.


Faster Slew Speed - Improved gearing and motors provide faster slew speeds than ever before with a maximum slew rate of over 5 degrees per second.


Accuracy - The hallmark of any Celestron Telescope Mount is its ability to find, center and track celestial objects with the highest degree of accuracy.


Pointing - With just a standard hand control alignment, CGE Pro has the ability to center a star in your eyepiece or CCD chip to within 5 arc minutes. Using NexStar''s advanced pointing features such as Calibration Stars, Sync and Precise GoTo, further improves the pointing accuracy to as low as 1 arc minute in the desired region of the sky.


Tracking - With larger .75" pitch diameter worm, precision made cut-steel gears in gearboxes, and seven slot skewed armature motors, the Celestron Telescope CGE Pro delivers smooth +/- 5 arc second tracking accuracy typical unguided periodic error, which can be further reduced with PPEC


Mount Calibration - Celestron''s NexStar hand control has built-in compensation features essential for accurately placing small objects on the center of your CCD chip or high power Celestron Telescope Eyepiece. Aligning on multiple Calibration Stars creates a model of the opto-mechanical inaccuracies inherent in all equatorial mounts. This model is stored within the hand control and is used to compensate for these inaccuracies, thus improving your pointing precision each time you slew your Celestron Telescope.


In addition to these improvements, the Celestron line of German Equatorial mounts has long been recognized for features preferred by visual observers and astrophotographer alike. Among them include:


Portability - Set up and transportation of the CGE Pro telescopes is made easy by separating the mount into smaller, easy-to-carry components. Unlike fork arm mounted telescopes, the CGE''s optical tubes can be quickly removed from their mounts making even the CGE Pro Celestron Telescope easily assembled in minutes.


Stability - Recognized for superior stability, German Equatorial mounts place the center of gravity directly over the tripod legs and can be easily polar aligned without the use of an optional equatorial wedge. This proven design reduces the "tuning fork" vibration that can be associated with undersized fork mounts. An improved Super HD Tripod supports the CGE Pro mount. This fully extendable Celestron Telescope Tripod is made from the finest 2.75" stainless steel and can be raised to a height of 55". The tripod uses a dual leg support for maximum rigidity with an upper leg brace to provide an outward preload and a lower leg brace providing inward tension.


Balance - CGE Pro Equatorial mounts can easily be balanced in both axes. Simply sliding the counterweight for Right Ascension and moving the optical tube along its dovetail mounting for Declination, accomplish balancing the weight of camera equipment and other visual accessories. This means that no additional weight needs to be added to balance the Celestron Telescope when additional accessories are added.


Clearance - CGE Pro mounts support their tubes at a single contact point allowing the tube to move freely around its polar axis without making contact with the Celestron Telescope Mount. Software features allow the user to set the mount''s slew limits to guaranty safe motion. This is particularly useful when adding photographic and CCD instruments that extend from the rear of the telescopes.


All CGE mounted Celestron Telescopes are compatible with Celestron''s SkySync GPS accessory. Combine the GPS and built-in real time clock and these telescopes will keep track and remember their exact location and time without having to enter the information into the hand control.


Don'''t forget... Additional Celestron Telescope Eyepieces are also available - along with an extensive array of Celestron Telescope Accessories, too!
