Celestron NexStar Evoution Overview
The Celestron NexStar Evolution 9.25 235mm f/10 AZ GoTo Schmidt-Cassegrain OTA & Mount is a complete powerful, portable, versatile, and user-friendly observation platform that can be used for observing everything from the moon and planets to deep-sky objects like galaxies and nebulae. Included with the optical tube assembly is a single arm fork mount, a NexStar controller, and a sturdy stainless steel tripod.
The Celestron NexStar Evolution 9.25 235mm f/10 AZ GoTo Schmidt-Cassegrain OTA & Mount 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 multicoating system, light transmission is increased through the entire optical path with anti-reflection multicoated lenses and highly reflective multicoated four-element rare-earth glass mirrors. 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 Wi-Fi provides the connection to the app and expands its capabilities, including an expanded database of over 120,000 objects with detailed information on more than 200 of those objects. Second is the iconic 2-line 16-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 a mobile device, the system can assist in properly aligning the scope, provide tours of the objects and events visible whenever and wherever you’re viewing, and allow for manual direction and slew control.
Designed for portability, the Evolution features a long-life lithium-iron phosphate battery that provides 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, USB charging port, and built-in Wi-Fi module. Manual clutches in both altitude and azimuth enable you to manually move and point the telescope when it’s powered off.
