The Vixen POLARIE U Star Tracker in Detail:
Star-scape photography (stars and landscape).
A silhouetted landscape on earth is photographed together with the starry sky. The beauty of a landscape and the starry sky can be shown together on one photo. POLARIE U opens up a wonderful foreign world of star-scape photography and makes this possible for both beginners and advanced photographers.
Conventional telescopic astrophotography photographs a relatively narrow area of the sky. Star-scape photography mainly uses a wide-angle lens and takes impressive photos in which stars, and other celestial targets such as the majestic Milky Way and landscapes are combined. The possibilities of the compositions are endless and a completely new kind of landscape photography opens up.
Weight reduction of more than 20% and improved load capacity.
The structure of the original POLARIE has been completely changed. The distance between the two bearings that support the rotating shaft is about four times the distance of the previous model. This leads to a higher load capacity despite the weight reduction of 20%. The maximum load capacity is 2.5 kg (approx. 2.5 kg at 10 cm from the center of rotation) when used for wide-field astrophotography. The maximum load capacity is increased to 6.5 kg (approx. 2.5 kg at 10 cm from the center of rotation) when a POLARIE Multi mounting block (optional) and a dovetail slide rail DD (optional) are combined. In addition, used in vertical configuration, the POLARIE U can reach a load capacity of 10 kg (approx. 10 kg 10 cm from the center of rotation) for time-lapse photography and is therefore suitable for heavy camera equipment.
Settings via Smartphone
Communication between tracker and smartphone via the Vixen Polarie U App enables various settings via smartphones or tablet. For star/landscape photography, the speed is selected in user-defined mode, and for time-lapse photography, settings for interval time, exposure, and rotation speed can also be easily programmed.
Five different speeds:
Star-scape photography (half star speed). This setting is intended for displaying a landscape together with the starry sky. The stars are not tracked exactly, but slower in order not to blur the landscape in the foreground. This way you get beautiful images of the landscape and the starry sky.
Wide Field Astrophotography (Star Speed)
When this mode is selected, the POLARIE U follows the stars at the same speed as the daily movement of the stars. In this mode, widefield long-time exposures of comets, nebulae, star clusters and the Milky Way are made and tracked precisely.
Solar Tracking (solar speed)
For recording solar eclipses over a long period of time.
Moon Tracking (moon speed)
For recording lunar eclipses over a long period of time.
This allows you to set the POLARIE U to the desired tracking speed. The initial setting is four times the star speed. If you want to change the setting for a different speed, a smartphone or other wifi device and application software are required.
It is possible to stop the movement of the camera during the exposure and restart it after the end of the exposure. It is also equipped with a camera connector (shutter release) that controls the camera shutter during shooting with SMS or interval shooting. If the camera in use is connected with the cable release, the settings can be easily adjusted using a smartphone. A Wi-Fi connection is required when using this feature. An additional cable is required to connect the camera and POLARIE U together.
POLARIE is a new and unique camera accessory for photographing the night sky, with perfectly point-like stars being tracked. Using the simplest solution, it makes the experience of photographing the night sky more accessible for everyone. The multi-functional mode dial is adjustable for sky- and landscape-, moon-, sun- and star-tracking. Polar altimeter for a fast focus. Also included: USB connection for external power supply and a built-in compass for quick orientation. Available as optional extra accessories are a polar finder telescope for exact alignment with the celestial pole for long-exposure photography including into the telephoto range, and a tripod.
