Celestron Astro Fi 90 mm is a robust and easy-to-use lenticular telescope for computerized assembly. Among many telescopes of this type, it is distinguished by the ability to remotely tune to the desired object using a free smartphone or tablet application. The telescope assembly is connected wirelessly via your own WIFI network with a mobile device with Celestron SkyPortal installed.
This application does not require practically any preliminary knowledge and provides all important information about the observed star, planet or nebular object. It can also be used in many other ways, e.g. as a compass for orientation at the observation site.
