The compact and portable design of the ETX-80AT-TC Refractor Go-To Telescope will have you out observing the inexhaustible quantity of visible phenomena in no time. The ETX-80AT-TC double-tine, fork mountings include high-torque DC motors on both telescope axes, permitting electronic operation from the included plug-in AutoStar hand controller. You can instantly select any speeds simply by pressing the SPEED button on the AutoStar controller. As an added bonus, the ETX-80AT-TC telescope comes with Meade's ultra-sturdy, easy-to-use, Standard Field Meade #882 Tripod that features micrometric controls to provide precise equatorial alignment of your telescope at any observing latitude from 20 to 90 degrees. This alignment is useful for fully automatic tracking of celestial objects in right ascension. Should you decide to look at the surface of your own planet for a while, the Altazimuth (90-degree) Orientation option provided by this tripod is useful for terrestrial viewing. This is also the preferred mode for astronomical applications when you use the AutoStar controller for automatic object location and tracking.
