More information
The refractor telescope Astro Fi Celostron 90 is a refractor, 90mm opening, with Altazimuth and perfect frame for planetary observation. Up to here it could be a basic initiation telescope, but in it we found a novelty that has not been developed until now, the possibility of controlling the telescope from your mobile device through the wi-fi connection.

The SkyPortal application for Android and IOS will allow you to configure the control of your telescope, which already has an integrated Wi-Fi communication system. To start the observation you will only need three celestial points , no matter what they are, and he will automatically calculate your position, from here the same function of SkyAlign will take you on a tour of space. This telescope allows memorizing up to 120,000 celestial objects .
