The NexStar Evolution 9.25" 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 or astro-imaging platform for the Moon and planets.

The Evolution comes with two ways to use and control it. There is the 4-line 18-character NexStar computer controller. This is a wired piece of hardware with a database of over 40,000 celestial objects plus several astronomical catalogs including the Messier and Caldwell. To expand the usability of the scope, download Celestron's free Navigator app for Android and iOS smartphones and tablets. The scope's Wi-Fi provides the connection to the app and expands the capabilities and functionality. Whether using the controller or mobile device, the system can assist in properly aligning the scope, provide tours of the objects and events visible whenever and wherever the user if viewing, and allows for manual direction and slew control.

Designed for portability, the Evolution features a long life lithium-ion phosphate battery providing up to 10 hours of continual use on a single charge. The scope comes with an AC power supply with plugs for the US, EU, UK, and AU outlets. The battery powers the servo motors, auxiliary accessory ports, a USB charging port, and the built-in Wi-Fi. Manual clutches in both altitude and azimuth enable users to manually move and point the telescope when it's powered off.
