TELESCOPES & ACCESSORIES

Item #526. CELESTRON NexStar 114GT.  A 4.5" (114mm) diameter Newtonian reflecting telescope from America's premier maker of quality telescopes. This unit is used but in excellent operating and cosmetic condition.
     NexStar features include an aluminum tripod and computerized mount with hand controller that provides for a 4 degree/sec slew rate, a polar alignment function and a 4,000 object database with Go-To capability.
    IMPORTANT: While the standard factory accessories included with NexStar include two oculars and a 12-volt (eight AA) battery pack, this scope includes instead only one 15mm Plossl ocular that delivers crisp images at 67X and an AC-to-DC power supply. Also NOT included is the The Sky Level 1 Astronomy Software and Personal Computer disc. All other factory stock items are complete and in good working order.
    Please note that this item can be shipped only to U.S. addresses.
