NEW PRODUCT--AVAIL.MID JUNE 2009 The CGE Pro 1100 Schmidt-Cassegrain 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., this 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".
This telescope is especially at home as a solid platform for long exposure photography with optional CCD cameras or photographic equipment; it is a serious scientific research tool that comes with Celestron's premium StarBright XLT coatings.
For astrophotography, the German Equatorial mount offers easier balancing, unlimited space at the rear of the telescope tube to mount a camera, and whole sky access. Now you can enjoy all of the NexStar software and database features with the extra stability and portability of a German Equatorial mount.
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 design advantages:
Increased Payload Capacity ý With a maximum payload of 90lbs the CGE Pro mount is able to hold the 11" telescope more securely even when fully loaded with all your imaging gear. All-Star Polar Alignment ý Choose any bright alignment star for a software assisted alignment of the mounts polar axis that will have you ready for imaging even if you can't see the North Star. No-Tool polar alignment ý Larger hand knobs for both Altitude and Azimuth adjustments. Meridian Tracking ý Extended tracking pass the Meridian of up to 20 degrees of uninterrupted imaging through the best part of the sky. Faster slew speed ý Improved gearing and motors provide faster slew speeds than ever before with a maximum slew rate of over 5 degree/per second.
Accuracy ý The hallmark of any telescope mount is its ability to find, center and track celestial objects with the highest degree of accuracy.
Pointing ý 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 ý With larger .75" pitch diameter worm, precision made cut-steel gears in gearboxes, and seven slot skewed armature motors the CGE Pro delivers typical tracking performance of +-9 arc seconds, which can be further reduced with the mounts permanent periodic error correction (PPEC).
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 ý 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 Pro1400 easily assembled in minutes. Stability ý 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 ýtuning forký vibration that can be associated with undersized fork mounts. An improved Super HD Tripod supports the CGE Pro mount. This fully extendable 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 ý 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 telescope when additional accessories are added. Clearance ý 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 telescope's mount. Software features allow the user to set the mounts 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 telescopes are compatible with Celestron's CN-16 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.
