Celestron C14 SCT OTA - CGE Dovetail

The Celestron C14-AF XLT is a world-class optical tube designed to deliver exceptional detail across a wide range of deep-sky and planetary targets. As an observatory-ready instrument and one of the largest in its class, it provides more than three times the light-gathering power of an 8-inch telescope. Its powerful optics allow you to observe remarkable details on Jupiter and Mars, Cassini’s Division in Saturn’s rings, and even the distant planets Uranus and Neptune. The C14 combines serious light-gathering capability with a durable aluminum optical tube, making it an excellent choice for advanced visual observing and astrophotography. Celestron’s patented StarBright® XLT optical coatings enhance light transmission and contrast, producing brighter deep-sky images and shorter exposure times. With an f/11 focal ratio and Fastar compatibility, the C14 offers additional flexibility for astrophotography. It can also be paired with an f/6.3 focal reducer for even more imaging options. The C14-AF XLT features a CGEM-style dovetail bar, allowing it to be mounted on a wide range of computerized telescope mounts. This flagship optical tube is built to deliver exceptional performance for serious visual observation and astrophotography.

StarBright XLT coatings

StarBright XLT is Celestron’s revolutionary optical coating system. It consistently outperforms all other coatings in the commercial telescope market. There are three major components that make up our StarBright XLT high-transmission optical system design:

• Unique enhanced multi-layer mirror coatings made from precise layers of aluminum, SiO2 (quartz), TiO2 (titanium dioxide), and SiO2 (silicon dioxide). Reflectivity is fairly flat across the spectrum, optimizing it for both imaging and visual observing.
• Multi-layer anti-reflective coatings made from precise layers of MgF2 (magnesium fluoride) and HfO2 (hafnium dioxide). Hafnium—a rare element that costs nearly $2,000 per kilogram—gives us a wider band pass than the titanium used in competing coatings.
• High-transmission water white glass is used instead of soda lime glass for the corrector lens. Water white glass transmits about 90.5% of light without anti-reflective coatings; that’s 3.5% better than uncoated soda lime glass. When water white glass is used in conjunction with StarBright XLT’s anti-reflective coatings, the average transmission reaches an astonishing 97.4.
