User manual for the Celestron NexStar Evolution 8" Schmidt-Cassegrain 12091
The user manual for the Celestron NexStar Evolution 8" Schmidt-Cassegrain 12091 provides
necessary instructions for the proper use of the product Optics - Telescopes - Catadioptrics (Cassegrain).
The NexStar Evolution 8" Schmidt-Cassegrain Telescope from Celestron is a powerful, versatile and user-friendly Schmidt-Cassegrain style telescope that can be used for observing everything from the Moon and planets to deep sky objects like galaxies and nebulae. Using Celestron's improved proprietary StarBright XLT multi-coating system, light transmission is increased throughout the entire optical path with anti-reflection multicoated lenses, highly reflective multicoated mirrors, and 4-element rare-earth glass. While the focal ratio is a slow f/10, the scope's precision tracking system allows it to be a competent astrophotography/astroimaging platform for the Moon and planets.
