The CGE-1100 Schmidt-Cassegrain Telescope is part of Celestron’s “Top-of-the-Line” German Equatorial mounted 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 model features our premium StarBright XLT coatings which further enhance contrast throughout the optical system.
This telescope is especially at home as a solid platform for long exposure astro imaging with optional CCD cameras or photographic equipment; it is a serious scientific research tool capable of serious research. 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. Couple these mechanical features with other performance features like a designated autoguider port, permanent periodic error correction and equatorial alignments this instrument is a very serious tool for visual or imaging applications.
As a visual instrument you can search for all of the Messier Catalog, 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 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.
