The CGE computerized series is Celestron’s newest line of observatory class
Schmidt-Cassegrain telescopes. Offered in 8", 91/4", 11" and 14" apertures, they all come
mounted on the state of the art CGE GoTo German Equatorial 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 Celestron CGE telescopes use the same optical tube assembly (OTA) as the 8GPS,
C91/4-S and 11GPS telescopes while the CGE 1400 uses the classic C14" optical tube
assembly. All include new high efficiency XLT coatings. The 8", 11" and 14" all have
Fastar compatible optics for wide field f/2 CCD imaging.

In addition to being fully computerized with a database of over 40,000 celestial objects, the
CGE German Equatorial mount offers numerous design advantages:

Portability – Set up and transportation of the CGE telescopes is made easy by separating
the
CGE instruments 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 1400 easily assembled by only one person.

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
mount. This fully extendable tripod is made from the finest cold rolled carbon steel and can
be
raised to a height of 50". 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 equatorial mounts can easily be balanced in both axes. Simply 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 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. 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 Hibernate mode and these telescopes will keep track and
remember their exact location and time without having to enter the information into the hand
control.

Other CGE Capabilities Include:

Mechanical Features

Carbon Fiber Tube – Strong and lightweight with 1/4 the thermal expansion of an aluminum
tube on the 8" and 11" models. Scratch and dent resistant.
CNC machined aluminum and stainless steel components
Autoguide port, PC port and auxiliary ports located on the electronic pier.
Strain relief power cord cable protection
Backlit power switch
Drive Motors – Made in the U.S.A., Pittman® LO-COG™ brush-commutated DC motors offer
smooth, quiet operation and long life. The motor armatures are skewed to minimize cogging
which is required for low speed tracking. Windings are resin impregnated for greater reliability
in incremental motion applications.
Precision Bronze Worm Gear – 32 pitch, 5.625" pitch diameter, 180 tooth bronze gear
manufactured in the U.S.A. by W. M. Berg, Inc. Manufactured to AGMA Quality Class 10
standard, which minimizes total composite error and backlash.
Bearing and Shaft – Stainless steel worm shaft has 0.4375 pitch diameter and is preloaded
with two ball bearings. The worm is made from a single piece of steel (rather than a two-piece
worm-and-shaft assembly) to minimize run-out, which is a source of periodic error.
4 point RA clutch system for no-slip pointing precision
Schmidt-Cassegrain mechanism that moves the primary mirror to adjust focus is supported
by
two pre-loaded ball bearings, minimizing the “mirror flop” typical of bushing focus
mechanisms.

Celestron CGE 800 XLT Schmidt-Cassegrain on a Computerised German Equatorial Mount.

The CGE-800 Schmidt-Cassegrain Telescope is part of Celestron’s “Top-of-the-Line” German
Equatorial mounted astronomical telescopes. The CGE-800 is the most portable of the four
models. This telescope is especially at home as a solid platform for long exposure
photography with optional CCD cameras or photographic equipment. Using an f/6.3 Focal
Reducer or Fastar accessory makes it usable with a wide variety of CCD cameras. 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. This, coupled with the CGE line’s GoTo capability,
makes it an unbeatable instrument for its size. As a visual instrument you can search for all
of
the Messier Catalog objects, and you can see hundreds of other, less famous, but 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.

Celestron CGE 1100 XLT Schmidt-Cassegrain on a Computerised German Equatorial Mount.

The CGE-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-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. 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. Using an f/6.3
Focal Reducer or Fastar accessory makes it usable with a wide variety of CCD cameras.

Celestron CGE 1400 XLT Schmidt-Cassegrain on a Computerised German Equatorial Mount.

The CGE-1400 Schmidt-Cassegrain Telescope is part of Celestron’s “Top-of-the-Line” German
Equatorial mounted astronomical telescopes. With over three times the light gathering power
of an 8” telescope, this observatory-class instrument is Celestron’s largest optical system in
its class. 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 easy accessibility for
attaching equipment. Used in the Fastar configuration for f/2 CCD imaging, the CGE 1400
can
display the faint detail of a telescope twice its aperture used visually. With sophisticated
software features like Hibernate function, the CGE 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 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
