Celestron C11 SGT Advanced Computerized Telescopes are the largest Computerized Celestron Scopes in Celestron Advanced Series. Celestron C 11 S GT Telescopes come mounted on CG-5 GT Computerized EQ Mount and allow access to features like Automatic Star Alignment capability and GoTo slewing to over 40,000 objects. Couple solidly-built Celestron CG-5 German Equatorial Mount with the included Celestron NexStar Computerized Control System to utilize many of the same functions and features as most advanced Celestron Go To Telescopes . Celestron CG 5 German Equatorial Mount has precision worm gears on both axes for extremely smooth stability. The key element that makes this system the most stable in its class is the NEW Heavy-Duty Tripod with larger and more substantial legs that offer excellent damping characteristics for more stable views. Celestron CG-5 Mount also has a convenient latitude scale for easier alignment and an optional polar finder scope for the ultimate in precision alignments. Celestron 11" Schmidt Cassegrain Computerized GoTo Telescopes are also upgradeable to GPS with the optional Celestron CN16 GPS Accessory (# 93966) allowing Celestron C 11 S GT Telescope to pinpoint your position on the earth, the date and time, making the alignment process faster and easier than ever before!
Equipped with high speed motors and hand control, C11-SGT allow you to remotely slew your 11" Celestron Advanced Computerized Telescopes 11067-XLT to desired objects quickly and accurately. No matter at what level you are starting out, Celestron C11-SGT Schmidt-Cassegrain Computerized Telescope is the precision instrument which will satisfy your needs both visually and photographically. Celestron Advanced Computerized C 11 S GT Schmidt-Cassegrain Telescopes (model 11067-XLT) come with Celestron SarBright XLT Coatings :
With Celestron StarBright XLT Optical System Design you'll see the light!One of the most important factors in the evaluation of a Schmidt-Cassegrain Telescopes Optical System performance is its transmission " the percentage of incoming light that reaches the focal plane. The design of Celestron 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:Celestron Strar Bright XLT 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 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 Celestron Star Bright 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.
Due to their size, large Celestron telescopes can be shipped via Ground only. No express shipping is available for large Celestron Astronomical telescopes
