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 CGE1400 instrument is Celestron largest optical system in its class.

• 11063-XLT: Celestron CGE 1400 Schmidt Cassegrain GO TO Telescope w / StarBright XLT Coatings

Celestron CGE 1400 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.

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. CGE-series 1400 Telescope 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 Celestron CGE1400 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.

With StarBright XLT Optical System Design you'll see the light! One of the most important factors in the evaluation of a Schmidt-Cassegrain telescope 's optical system performance is its transmission - the percentage of incoming light that reaches the focal plane. The design of the XLT System accomplishes two crucial objectives: Develop a coating system that is optimized for visual use and for CCD/Photographic imaging.

There are three major components that make up Celestron StarBright XLT high transmission optical system design:

• 1) Unique enhanced multi-layer mirror coatings: Celestron mirror coatings are made from precise layers of Al (Aluminum), SiO2 (quartz) and TiO2 (Titanium Dioxide). Reflectivity is fairly flat across the spectrum, optimizing it for both CCD imaging and visual use.
• 2) Multi-layer anti-reflective coatings: Coatings are made from precise layers of MgF2 (Magnesium Fluoride), and HfO2 (Hafnium Dioxide). Hafnium gives a wider band pass than Titanium, used in comparable coatings.
• 3) High Transmission Water White glass : Celestron Schmidt-Cassegrain optical systems with optional StarBright XLT coatings use Water White glass instead of Soda Lime glass for the corrector lens. Water White glass transmits about 90.5% of light without anti-reflective coatings. That is 3.5% better transmission than uncoated Soda Lime glass. When Water White glass is used in conjunction with StarBright - XLT 's anti-reflective coatings, the average light transmission reaches 97.4% - an 8% improvement!

These three components of Celestron StarBright XLT coatings result in one of the finest coatings available. The peak light transmission for the systems is 89% at 520 nm. The overall system transmission is 83.5% averaged over the spectrum from 400 to 750 nm. Click here to see details about StarBright XLT.
