75505 Polarie Star Tracker
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.
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.
It’s compact size and minimal weight means you can take the Polarie anywhere to photograph the night sky.

This can be beneficial for solar imaging or imaging at night when Polaris cannot be seen (for example from a south-facing balcony or garden). The unit attaches to the accessory shoe on the Polarie Star Tracker or any instrument equipped with a camera accessory shoe.
