This is the motorized chair that allows star gazers and amateur astronomers to lie down in a comfortable position for night sky binocular viewing. The computer-controlled motor quietly and smoothly turns the chair a full 360, guided by a miniature joystick built into the binocular mount (binoculars not included) and powered by a rechargeable battery that provides up to four evenings use per charge.The chairs recline is controlled by subtle body movements; the precise counterweight system allows you to sit up or recline by leaning slightly forward or backward, requiring minimal effort to find an ideal position. Convenient thumb locks allow you to easily maintain your chosen settings. A built-in green laser pointer assists in object location, eliminating the guesswork and trial-and-error involved in panning to find a specific celestial object. The rugged case-hardened aluminum base provides stability without adding excessive weight, and the chair rotates smoothly on quiet, long-lasting Teflon ball bearings. The fully adjustable chair is also suitable for deer, bird, and whale watching.The easily portable unit requires no tools for setup. 34" H x 26" W x48" L. (45 lbs.)
