  • Celestron NexStar Evolution 9.25 235mm f/10 Schmidt-Cassegrain GoTo Telescope

    Representing the largest aperture in the series, the NexStar Evolution 9.25 235mm Schmidt-Cassegrain Telescope from Celestron is a powerful yet portable user-friendly scope 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.

    The Evolution comes with two ways to control it. The first is to simply download Celestron's free Navigator app for Android and iOS smartphones and tablets. The scope's on-board WiFi provides the connection to the app and expands the capabilities and functionality, including a 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 hand 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.

    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 Wifi. Manual clutches in both altitude and azimuth enable users to manually move and point the telescope when it's powered off.
