The ETX-80AT is a fully automated GO TO telescope with over 1400 of the sky's best celestial objects in its computer database. The large 80mm objective lens delivers bright, high definition images of celestial and terrestrial objects. The revolutionary Meade Autostar system facilitates fully automatic astronomical object-location. Just select the object shown on the Autostar display, press GO TO, and the telescope automatically moves to the object and places it in the telescopic field of view! Autostar also tracks the object automatically, compensating for the earth’s rotation.
