This is the telescope that slews to any celestial object to which it is commanded wirelessly by an app from an iPhone, iPad, or Android smartphone. The app synchronizes your device’s built-in GPS with the telescope’s database of 120,000 celestial objects, including 220 of the best deep sky and solar system objects. Tapping on a celestial object in the app automatically aligns the telescope to point at the object in the sky. The app includes written context about the object while the telescope observes the real thing in precise clarity with a 90 mm aperture and a refractor optical design with a 910 mm focal length that yields a maximum usable magnification of 213X using two Kellner eyepieces. Its precision optics incorporate fully-coated antireflection glass for aberration-free images. Requires eight AA batteries. 54" H x 37" Diam. (14 lbs.)
