This is the star-tracking telescope that provides a guided audio tour of the night sky. It provides over four hours of narration that covers 500 objects from its vast 30,000-object database, including planets, galaxies, and nebulae, tracking each in real time while maintaining focus. This reflector has a 130mm objective mirror that gathers optimal light from deep sky objects at magnitudes imperceptible to the unaided eye and delivers crisp images that are rich in contrast with a 1,000mm focal length and 9mm and 26mm Super Plossl multicoated eyepieces. Its integrated bubble level/compass assists initial alignment while its red dot viewfinder provides impromptu spotting. Sturdy aluminum tripod provides optimal image stability and convenient adjustability. Requires six AA batteries. 58" H x 24" Diam. (15 1/4 lbs.)
