The NexStar Evolution 6 (150mm) Schmidt-Cassegrain Telescope from Celestron is a powerful, portable, versatile and user-friendly telescope that can be used for observing everything from the Moon and planets to deep sky objects like galaxies and nebulae. Using Celestron's proprietary StarBright XLT multi-coating system, light transmission is increased throughout the entire optical path with anti-reflection multi-coated lenses, highly reflective multi-coated 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.

The Evolution comes with two ways to use and control it. The first is to simply download Celestron's free Navigator app for Android and iOS smartphones and tablets. The scope's WiFi provides the connection to the app and expands the capabilities and functionality, including an expanded database to over 120,000 objects with detailed information on more than 200 of those objects. Second is the iconic 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. 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.
