The night sky over the Large Binocular Telescope (LBT) on Mt. Graham in Arizona. Bright winter star Procyon appears on the upper right and the Beehive star cluster (M44) is on the left. Click on the second photo to see a closer view of the star cluster above the telescope. 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.
