If you're a beginning or amateur astronomer looking for an affordable computerized telescope, the Celestron NexStar SLT Series Computerized Telescope is a great choice. Observe the moon's surface, Saturn's rings and more with its star locating telescope reflector; it's easy to find what you're looking for with the StarPointer Finderscope. Simply align the red dot with the object in the sky to point your telescope in just the right direction. Keep the hand control mounted to the sturdy, steel tripod or remove it for remote operation – use it to select the catalog, change slew speed, view information about an object or check to see if a star or planet is visible in the sky. To locate something specific, simply aim the scope towards three bright points and let the SkyAlign technology do the rest. Database can download new information from a PC, and there's an additional port for electronic accessories. Package includes NSOL software so you can control your telescope from a computer. Set up your NexStar SLT quickly and easily, without tools, and then take it anywhere – it runs on AA batteries (not included).
