Vixen have launched the Polarie Star Tracker, which allows users to take pin sharp photos of stars and constellations.
The Polarie device is fitted between the tripod and the camera, and is designed to follow the movement of the stars caused by the earth's movement, to avoid star trails and keep your images crystal clear.
The Polarie can be used to take wide field images of constellations with ease. Designed to work with wide angle lenses, the Polarie can operate for more than two hours on 2 AA batteries.
The Vixen Polarie is available for £399. For more information, visit the Vixen website
