Celestron's SkyScout personal planetarium ($399 at Amazon.com) lets stargazers instantly identify or locate over 6,000 celestial objects, then provides commentary on the planet or star. It employs a pair of ADXL322 iMEMS accelerometers from Analog Devices, which complement the unit's GPS receiver. They provide accurate inclination measurements so the SkyScout knows what angle the device is pointing relative to the earth's surface. The camcorder-sized device won an adventure gear award from National Geographic last year.
