Give your IntelliScope Dob a brain! Simply plug the Computerized Object Locator into the base of most SkyQuest XT IntelliScopes (not compatible with XX12i) and you're all set to locate and view any of 14,000 celestial objects . You just select an object from the user-friendly menu buttons, then move the telescope in the direction of the guide arrows on the LCD screen. In seconds, the IntelliScope's two high-resolution digital encoders pinpoint the object, placing it right in the telescope's field of view. The internal database includes 837 stars (including double and variable stars), 7,840 NGC objects, 5,386 IC objects, 101 Messier objects, 8 planets, and 99 user-entered objects. It also features 12 monthly tours of the coolest objects. Whether you are an entry-level or expert astronomer, the Object Locator makes observing the night sky with your IntelliScope Dob incredibly easy and fun.
