Astonishing stabilized time-lapse showing the Earth's rotation from the ground

Photographer Eric Brummel created this magnificent time-lapse video of the Milky Way in which the sky is stabilized so you can experience the Earth's rotation. He captured the footage at Font's Point, Anza-Borrego Desert State Park, California. From Universe Today:

Eric created this time-lapse by using a star-tracker with his camera. A star-tracker rotates the camera at the same speed as the Earth, but in the opposite direction. It has the visual effect of stabilizing the sky. Usually, star-trackers are used to stabilize the camera during a long exposure, to avoid blurry or streaked stars in the image.
