The POLARIE U is an ultra-compact automatic star tracking device that can easily be transported. In addition to functions of conventional star trackers that move a camera for long exposure according to the diurnal motion of the celestial objects, it features a function for customizing rotation speeds using a smartphone and can control the intervals of shots by adjusting the shutter release. By linking the motion of the POLARIE U with the shutter release, you can easily set up complex shooting controls required for interval photography and time-lapse photography with your smartphone.
