About the Vixen Polarie Star Tracker...
We are proud to introduce the Vixen Polarie Star Tracker for Astrophotography. This compact mount platform allows you to capture night scapes and star images with elegance and ease. David Snay writes in Astronomy Technology Today "If you are looking for an ultra-light, portable platform to use for wide field astrophotography, the Polarie definitely deserves serious consideration."
Set up is simple and fast! The Vixen Polarie Star Tracker attaches to a standard camera tripod and can accept any digital camera weighing up to 7 lbs. Using the included compass on the Polarie, orient the mount to face north. This easy to use mount features a North Star alignment window that you point at Polaris. The Polarie can also use a polar scope for alignment. Once set, the Polarie tracks with the motion of the stars to eliminate "star trailing" on your photos resulting in sharp images of the Universe. The Polarie uses very accurate stepping motors and operates on any 2 "AA" batteries.
The Vixen Polarie Star Tracker is designed to not only be functional, but also to be compact and attractive, with its sleek design. The unit has no visible screws and although, not waterproof, it is designed to function in most weather conditions. In the March 2012 edition of Sky and Telescope Magazine Richard Tresch Fienberg wrote "Vixen definitely has a winner here. Polarie makes long exposure constellation photography easier than ever".
