Celestron Astro-Fi 90 Refractor Telescope

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 .
The multi-coated optics of this telescope follow the quality of Celestron, incorporating two eyepieces , 10 and 25mm (91 and 36X). The focal length is 910mm and the focal ratio is 10.1 . Therefore, it is a suitable instrument for planetary observation.
The kit comes complete with an Altazimuth fork mount , similar to that of the Celestron LCM series, and a very stable aluminum tripod .
