Celestron CGX 800 Computerized Telescope
The CGX 800 Telescope by Celestron is a 203 mm (8-Inch) Schmidt-Cassegrain Telescope on a CGX Mount.
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-inch Schmidt-Cassegrain 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 astroimaging 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-degree 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 some 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-Inch Celestron CGX apart from competitor models is simplicity and durability. The 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 Spaceshuttle 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!
All-Star Polar Alignment
Get ready for a night of astroimaging with your mount faster than previously thought possible with All-Star Polar Alignment. This innovative software solves the time-consuming problem of trying to pinpoint the North Celestial Pole.
The new Lithium Phosphate (LiFePO4) battery chemistry has significant advantages over other battery chemistries, great for those Astronomers on the go.
Celestron’s patented StarSense Technology makes it easier than ever to locate objects in the night sky, even if you’ve never used a telescope before. Turn it on and push ‘Align.’ In about three minutes, you’re ready to observe!
WiFi technology encircles the globe in a web of connectivity, knowledge, and information. Now, Celestron is using that same technology to allow stargazers to connect to the night sky and enhance their experience of the cosmos in fun and unique ways.
