Unlike other telescopes that require you to input data such as time, date, or zip code for initial set-up, this one performs all the work for you with the flip of a switch. It uses a GPS module to gather the date, time, and location automatically, then orients itself relative to the night sky. Its built-in CCD camera locates a pair of alignment stars from its database of 100,000 celestial objects. The handheld controller allows you to select any number of galaxies, nebulae, stars, or planets; a press of the "Go To" button slews the scope to your selection. The telescope plays audio descriptions (voiced by Sandy Wood from "Star Date") for 450 objects, providing you with an audio guided tour of the heavens. The built-in camera lets you view images with an external monitor (not included) or you can save images to an SD card (not included). The telescope delivers crisper, cleaner images than many telescopes of larger aperture--its coma-free optics eliminate the optical aberrations found in other telescope designs. It has a 1,524 mm focal length that yields a maximum usable magnification of 350X. Precision optics incorporate UHTC-coated, BK-7 glass and a 6" Pyrex primary mirror. Requires eight C batteries. 64" H x 37" L x 37" W. (50 lbs.)
