Hooker Telescope, 100-inch telescope at Mount Wilson Observatory in California, US
The Hooker Telescope features a 100-inch primary mirror mounted on mechanical supports that distribute the weight through a mercury flotation bearing system.
From 1917 to 1949, this telescope maintained its position as the largest operational telescope in the world, enabling Edwin Hubble's revolutionary discoveries about galactic distances.
The Mount Wilson Institute organizes public viewing sessions through the Hooker Telescope, connecting visitors with astronomical research and scientific education.
The telescope operates at an elevation of 5,710 feet, requiring visitors to prepare for cooler temperatures and reduced oxygen levels during observation sessions.
The mirror's support system includes 36 adjustable pressure points that maintain perfect alignment regardless of the telescope's position in the sky.
