Celestron C6 SC XLT - 150/1500 mm Schmidt Cassegrain OTA

C6 - Schmidt Cassegrain

Aperture: 150 mm / focal length: 1500mm

The C6 gathers ca. 40% more light than a 5" (125 mm) refractor but is significantly more compact. It is ideal for both the beginner and the advanced amateur who pay attention on good optical performance and a transportable system.

The optical design
The C-6 by Celestron is a powerful but highly transportable Cassegrain system. With this 6" SC, Celestron has closed a relatively big gap between the smaller C5 and the C8. It accepts even 2" accessories with its SC thread - essential for wide field observation.

The internal focusing system
The advantages of focusing by moving the main mirror are undisputed. The only disadvange, the main mirror shifting, has been solved by Celestron. No disturbing shifting degrades the focus precision.

XLT Coatings
The multi-layer anti-reflective coatings allow very high light transmission. Especially around the wave length around 500nm, 10% more light are brought into the eyepiece. Here, the human eye is very sensitive.
