Celestron CGE Pro 925 SCT

'Top-of-the-Line' Computerized German Equatorial Mounted Astronomical Telescopes.
 

The CGE Pro 925 Schmidt-Cassegrain Telescope is part of Celestron's "Top-of-the-Line" computerized German Equatorial mounted astronomical telescopes. It is the most portable of
the three size models and comes mounted on Celestron's new CGE Pro EQ mount. This telescope is especially at home as a solid platform for long exposure photography with optional CCD cameras or photographic equipment. With over 9 inches of aperture and our
premium StarBright XLT coatings, the CGE Pro 925 gives you over 1000 times the light gathering power than the unaided eye.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 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.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 9.25" 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 5per 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.

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.
