Subaru Observatory

Subaru Observatory
The Subaru Telescope is an optical-infrared telescope at the 4,200m summit of Mauna Kea on the island of Hawaii. The Telescope is a new generation telescope not only because of the size of its mirror with an effective aperture of 8.2 meters, but also because of the various revolutionary technologies used to achieve an outstanding observational performance. An active support system that maintains an unprecedentedly high mirror surface accuracy, a new dome design to suppress local atmospheric turbulence, an extremely accurate tracking mechanism using magnetic driving systems, seven observational instruments installed at the four foci, and an auto-exchanger system to use the observational instruments effectively are just some of the unique features associated with this telescope. These sophisticated systems have been utilized and fine-tuned since the telescope's First Light.
