Introducing the first WiFi operated telescope!

Control your telescope through your iPhone, iPad or Android device (not included) with the free COSMOS Celestron Navigator app. The mobile app replaces the traditional telescope hand control for a 100% wireless experience. Just hold your smart device up to the night sky and when you find an object you’d like to view, tap the screen. Your COSMOS 90GT will automatically align to the object, while your screen displays information about it.

The 90mm refractor telescope has fully coated optics that ensure clear views of craters on the Moon, the rings of Saturn, the Great Red Spot on Jupiter, the Orion Nebula and so much more. The newly designed accessory tray includes storage for eyepieces along with a rubber-lined tray for your smartphone or tablet.

The Cosmos telescope emits its own WiFi connection so you don't have to worry about stargazing in an area with WiFi or mobile networks. Start up the SkyAlign technology by centering on three bright objects in the sky. Your Cosmos telescope will immeadiatly calculate it's position based on these points and then away you go! The app can even create a personalised SkyTour for you based on the best celestrial objects to view at your exact time and location.

Inspired by the FOX and National Geographic program Cosmos: A Spacetime Odyssey, this telescope comes with a StarPointer finderscope, 2 Kellner eyepieces, mirror star diagonal, free planetarium app, and Cosmic Calendar poster.
