Vixen Polarie Star Tracker is a technologically advanced, extremely compact and very easy to use paralactic platform for photographing the sky in wide frames. After setting on the world, or around the Polar Star (in the Southern Hemisphere on the South Blue Pole), it allows you to take long-term pictures of the sky using a DSLR or a mirrorless camera with a suitable lens. Surprising capacity: on the Polar you can "hang" a camera weighing up to 3 kg!
The device has an adjustment window, which should be directed to the Polarn Star using the integrated compass. It can also work with a dedicated polar spotting scope. After completing the setting procedure, Polarie tracks objects in several speed modes (star speed, 50% star speed, lunar and solar speed).
Polar beams can be used on both hemispheres of the globe, providing sharp and point-like images of stars.
Thanks to the use of a precise system based on the stepper motor, Vixen Polarie achieves high accuracy tracking. The device is powered by 2 AA batteries ("fingers"). The Vixen Polarie housing has been developed to ensure maximum functionality and compactness - it has no visible screws. Although Fleece is not a waterproof device, it enables work in virtually all weather conditions.
Fleece can be securely mounted on virtually any standard photographic tripod with the right stiffness. • tracking modes: star speed, 0.5 star speed, solar speed, lunar speed

• weight: 0.7 kg (without batteries)
• warranty: 2 years • Polar spotting scope (useful for accurately setting the Polar to the pole)
• field tripod with a ball head (dedicated to Velbon or any photographic with an appropriate stiffness with a 1/4 inch thread) • AA 1.5 V battery 2 pieces ("fingers") or AA rechargeable batteries (remember that the batteries are very cold in the cold - keep them in stock!)
• for long lighting, it is worth having an external power supply with a mini USB plug (4.4 - 5.25 V DC)
• Vixen Polarie does not take photos himself; the SLR cameras are best suited for taking photographs of the sky
• SLR cameras should have the option of shooting in the bulb mode, alternatively an ISO option above 3200 and a shutter speed of more than 30 seconds
• good for the camera to have a remote control function; it is worth getting a proper remote control, because it reduces or even eliminates vibrations when the shutter is released
• lens: preferably fish-eye or wide-angle , in general we recommend working in the focal range of 8-100 mm
• the lens should have the option of manual focus (manual focus) - the automatic mode (AF) rarely works in night sky photography
• watch with stopwatch will allow you to control the lighting time in bulb mode
• always in the field it is worth having: a waterproof bag for equipment, a flashlight with a red light, a rotating map of the sky
