According to the product description on the manufacturer's website, the device is pre-programmed to track the sky and stars.

"The Polaris is the world's first electric tripod head with a built-in camera interface controller. Polaris Astro Edition not only allows users to adjust the composition of a photo, but it allows users to program the smart head to capture a series of photos, easily track and take long exposures of stars, or create high resolution motion timelapses. The Polaris also offers a wireless connection so you can do all of the above remotely, as well as preview, review and download files via a dedicated app from almost anywhere."

"The Polaris has built-in modes such as people removal, panorama, motion timelapse, dynamic exposure timelapse, focus stacking and star tracking. With a battery life of over 24 hours and the ability to recharge while in use, the Polaris can shoot all day long and keep going. These modes work with a wide variety of cameras."

According to the review, it is mentioned that the product does not require polar alignment.
