Vixen Polarie U Star Tracker

Full review

The Vixen Polarie U is a compact star tracker designed for astrophotographers who want to capture the night sky without hauling around a full equatorial mount. Building on the legacy of the original Polarie, this updated version retains the portability that made it a favorite among travel and landscape astrophotographers while refining its internal mechanics for smoother, more accurate tracking. Powered by a simple battery setup and small enough to fit in a backpack, it allows users to photograph star trails, the Milky Way, and deep sky objects using nothing more than a camera, a sturdy tripod, and this single tracking unit mounted between them.

At its core, the Polarie U uses a precision stepper motor to rotate the camera platform at sidereal rate, counteracting the Earth's rotation so that stars remain pinpoint sharp during long exposures instead of streaking across the frame. Users align the unit with the celestial pole using either the built-in polar scope or an attachable polar meter, a straightforward process that takes just a few minutes once you're familiar with it. The tracker offers multiple speed settings, including half-speed and quarter-speed sidereal rates, which are particularly useful for foreground-blended nightscape shots where you want the sky sharp but don't want the ground to blur excessively during composite exposures.

Built with the same rugged, weather-resistant construction Vixen is known for, the Polarie U holds up well to the demands of field use, from dew-heavy nights to dusty desert locations. Its lightweight magnesium alloy body keeps the overall kit weight low, an important consideration for photographers who already carry heavy camera bodies, lenses, and tripods to remote shooting locations. Compatible with standard ball heads and counterweight systems for balancing longer telephoto lenses, the Polarie U bridges the gap between casual night sky photography and more serious deep sky imaging, making it a practical entry point for anyone looking to move beyond static tripod shots and start capturing the stars in genuinely sharp detail.
