Star Trails Over Large Binocular Telescope

A time-exposure image has captured star trails (due to the rotation of the sky) over the Large Binocular Telescope (LBT) on Mt. Graham in Arizona. The giant observatory combines two side-by-side 8-meter telescopes, make it one of the world’s largest telescopes. In resolution the two mirrors are equal to a single 23-meter mirror.
