What is the effective light-collecting area equivalent of the Large Binocular Telescope (LBT)?
Answer
A single, colossal mirror measuring 11.8 meters across
The LBT's configuration of two 8.4-meter primary mirrors delivers a combined light-collecting area equivalent to a single mirror measuring 11.8 meters in diameter, placing it at the forefront of light-gathering power for optical telescopes in North America.
