Some 40 years ago, Celestron founder - Tom Johnson - introduced the
first Celestron C8 telescope into the amateur astronomy market and began
a revolution. Now, Celestron's CGX-800 takes performance to a new level
beginning with the extreme optical quality of the 8" Schmidt
Cassegrian combined with Starbright XLT coatings mounted on Celestron's
newly engineered and innovative CGX mount. This new take on a tried and
true design has given the world another Celestron "classic" - one
capable of carrying the load securely and vibration free... and taking
both astro imaging and visual observing to new heights.
With a telescope capable of gathering 843X more light than the human
eye, the precise f/10 optics of the Celestron C8 SCT offer up an
incredible .57 arc seconds of resolution spread out over a 0.62 °
angular field of view. With a limiting magnitude factor of 14 and a
practical magnification limit of 480X, we're talking about a telescope
able to deliver remarkable planetary and lunar views. When sky permits,
you can expect to see details like delicate divisions in Saturn's ring
structure, details on Mars and follow Jupiter events like shadow
transits and Great Red Spot appearances with ease. Star clusters will
transform into well-resolved facets, galaxies will take on structure and
difficult double stars will yield their companions. With a low end
magnification limit of 29X, just add a wide field eyepiece, or open both
eyes wide with Celestron Stereo Binocular Viewers and enjoy panoramic
vistas of extended nebulae and sweep the heavens for every last photon!
What sets the 8" Celestron CGX apart from competitor models is
simplicity and durability. The 8" CGX was designed to be ergonomically
friendly with large Altitude and Azimuth adjustment knobs for quick and
easy procedures and adjustments. The intuitive All-Star system allows
users to choose any bright star from the NexStar hand control, while the
software calculates and assists with polar alignment. Then, just kick
back and enjoy. The CGEM-800 database will provide over 40,000 objects,
100 user defined programmable objects and enhanced information on over
200 objects for your celestial viewing pleasure.
The amazing new Celestron CGX Mount is the product of many long years of
rethinking and redesigning the German Equatorial mount from the top to
bottom. And the results speak for themselves- behold the finest example
of a GEM available, a true marvel of engineering that combines
surprising affordability with absolutely top notch quality. As a quick
summary- The CGX is simply more responsive, with spring-loaded worm
gears and belt drives that minimize backlash. Internal cabling means
power and accessory ports do not move with the mount, and there are also
home and limit switches, as well as internal hard stops for both RA and
Dec to prevent cable wrap and tripod strike. Ergonomics have also been
massively improved overall, ranging from the carry handles to the
adjustment knobs, making setup and takedown both infinitely easier.
Another fascinating feature is that there is a clear window built into
the motor covers, letting you keep an eye on the pulleys and belts.
Still more? Then consider the many features that make the Celestron CGX
a "gem" for astrophotography, too. It can be as simple as adding a
Celestron NexImage Solar System Imager to the CGX-800, or even just
adapting a digital camera. Not only will it track well past the meridian
for uninterrupted imaging through the most ideal part of the sky, but
the Permanent Periodic Error Correction (PPEC) will allow users to train
out the worm gears periodic errors, while the mount retains the PEC
recordings. Autoguide port and auxiliary ports are conveniently located
on the electronic plate for long exposure astrophotography and include a
designated six-pin RJ-12 modular jack and ST-4 compatible guide port.
You'll find an RS-232 communication port on hand control to control the
telescope via a personal computer and NexRemote telescope control
software, for advanced control. Software features include; mount
calibration, database filter limits, hibernate, five alignment
procedures, and user-defined slew limits. What's even better is that
it's all flash upgradeable. Just connect to the Internet to update your
hand control software and motor control units. You can even add an
optional Celestron GPS unit!
The Celestron CGX 800 carries on the Celestron C8 tradition of
performance, durability and value. Major colleges and universities
worldwide use Celestron telescopes in their astronomy programs and the
Celestron telescope line has been chosen over all competing models by
NASA to be taken on several space shuttle research missions. Why not add
a Celestron SkyScout to the fun? Carry on the trend started by the 2009
International Year of Astronomy with Celestron and bring that kind of
quality home to your backyard tonight... After all! They've only gotten
better with time and experience!
