DETAILS |
   
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
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.
