Celestron's newest line of observatory class German equatorial telescopes
The CGE Pro computerized series is Celestron's newest line of observatory class German equatorial telescopes. Offered with 9.25",
11" and 14" aperture Schmidt Cassegrain optical tubes, they all come mounted on the new state of the art CGE Pro GoTo mount.
The German Equatorial mount has long been the favored choice of astronomy buffs and astrophotographers because of its stability
and portability. More stable because the center of gravity is directly over the center of its base, more portable because it can
be broken down into smaller component parts for easy storage and transportation.
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.
The CGE Pro 1400 Schmidt-Cassegrain Telescope is part of Celestrons Top-of-the-Line German Equatorial mounted astronomical
telescopes. With over three times the light gathering power of an 8 inch telescope, this observatory-class instrument is
Celestrons largest optical system in its class.
The 11089 model also features our premium StarBright XLT coatings and is FASTAR compatible for F/2 wide field imaging. 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. German Equatorial mounts are recognized as being the superior choice for
astrophotography because of their rock solid stability, simple balancing and easy accessibility for attaching equipment. With
sophisticated software features like Hibernate function, the CGE Pro can maintain its star alignment night after night without
needing to be re-aligned, making it an ideal instrument for a permanent observatory facility.
The CGE Pro 1400 takes full advantage of its vast database of thousands of NGC and Abell galaxies as well as delivering a new
level of detail to all your favorite deep sky objects. Turn this scope 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 reach.
Fastar Compatible - Equipped with a removable secondary mirror for fast f/2 ccd imaging. Not only does imaging in the FASTAR
configuration allow for exposure times that are 25 times faster than at f/11, but also yields a field of view five times wider.
Perfect combination for imaging your favorite wide field objects in a fraction of the time. (FASTAR imaging require a third party
lens assembly in place of the secondary mirror).
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 – With a maximum payload of 90lbs the CGE Pro mount is able to hold the 14" telescope more
securely even when fully loaded with all your imaging gear.
* All-Star Polar Alignment – 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 – Larger hand knobs for both Altitude and Azimuth adjustments.
* Meridian Tracking – Extended tracking pass 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°/per second.
* Accuracy – The hallmark of any 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 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 – 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 – 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 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 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 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.
