The Polarie Star Tracker from Vixen Optics is an incredibly compact, motorized, tracking mount. The smooth and sleek, visually attractive Polarie attaches to a standard camera tripod with a ball head on one side and a DSLR or smaller camera on the other up to 4.4 lbs. Point the Polarie north with the integrated compass, use the alignment window by pointing it at Polaris, the North Star, or use an optional polar scope. Star trails and false fuzzies are eliminated in the time exposures of the attached camera as the Polarie tracks the motion of the stars across the celestial dome. Two user-supplied AA batteries can power the unit for ~4 hours or an optional external power supply (not included) can be used. Although, not waterproof, the Polarie is designed to function in most weather conditions. It weighs in at less than an incredible 1½ lbs and is about the size of a paperback book. This is one cool astrophotography star tracker.
