A Telescope That Finds Stars For You
Eyes to the skies
For non-astronomers, stargazing may seem simple: Just plop down a scope, and peer toward the heavens. It’s usually not quite that easy. Scopes can be tricky to set up and celestial objects elusive. The Celestron Cosmos 90 GT uses a Wi-Fi connection with a smartphone to do the hard work for you. To align it, users point it at any three bright objects in the sky; the scope uses them to triangulate its precise location. Through an app, users then select the celestial body they want to see from Celestron’s 120,000-entry database. Motors in the base position the scope in seconds.
