The Test-Bed Telescope 2 inside its dome during assembly
This picture shows the Test-Bed Telescope 2 inside its dome, right after it was positioned in place with the help of a crane, against the dramatic backdrop of the Atacama Desert. It is the clear, dark Atacama skies that make this location ideal for ground-based telescopes.
