75505 Polarie Star Tracker

Polarie Review The Vixen Polarie is a specialist photographic accessory that allows you to take pin-sharp photos of stars and constellations. It is designed to follow the apparent motion of the stars caused by the earth’s rotation, eliminating star trails.

Using the Polarie to take wide field images of constellations, shooting stars as well the Milky Way is surprisingly straightforward.

Polarie also enables you to photograph “starscapes” by adding a darkened landscape or silhouetted figure in the foreground of your frame.

Product features

The Polarie can be set up in a few minutes even by those not familiar with the exact position of the celestial pole. Simply turn the Polarie in the direction of the pole star using the supplied compass as a guide, then use the built-in latitude meter and polar sight hole to align the mount.

The Polarie is designed to work with camera lenses that take wide-angle images.

The Polarie can operate for more than 2 hours on two AA-size batteries.

Polarie Upgrade KitIt’s compact size and minimal weight means you can take the Polarie anywhere to photograph the night sky.

Polarie Upgrade Kits

If you already own a Vixen Polarie Star Tracker, the upgrade kits are a great way to get more from your mount. Both kits include all components required to increase the maximum payload of the Polarie from 2kg to 6.5kg.
A heavy-duty mounting block with Vixen-style dovetail attachment and quick release lever makes mounting and pointing larger accessories quick and simple. The mounting block has a clear central aperture that allows the polar alignment scope to be left in place after alignment.
The Dovetail Slide Bar DD enables you to quickly and easily mount and balance a DSLR with large telephoto lens using the counterweight bar. Alternatively, a second camera can be attached.
