Live View of the Sun
The three solar telescopes in this room use light coming through the coelostat in the dome overhead to provide live views of the constantly changing Sun. On clear days, the coelostat tracks the Sun and bounces sunlight off mirrors and through lenses to the telescopes at the three observing stations. Each one shows a live image of the Sun. The station in the center of the room has a white-light image reflected onto frosted glass. Dark sunspots are often visible in the image (as below).
