Celestron Astro Fi 5" SchmidtCassegrain Telescope

Smartphone control brings a notably clean, modern approach to this Celestron Astro Fi 5-inch Schmidt-Cassegrain telescope. With a 125mm aperture, 1250mm focal length and f/10 optical system on a computerised alt-azimuth mount, it combines compact proportions with the familiar versatility of a Schmidt-Cassegrain design.

Integrated Wi-Fi works with the free Celestron SkyPortal app for iPhone, iPad and Android devices, creating a direct wireless connection between the telescope and your smart device. SkyAlign technology supports quick alignment, while the app can slew the telescope to selected objects and display information on screen. XLT fully multi-coated optics, a StarPointer red dot finderscope, two Kellner eyepieces and a 1. 25-inch mirror star diagonal complete a well-specified setup for lunar, planetary and bright deep-sky observation.
