Subaru Telescope (すばる望遠鏡 Subaru Bōenkyō?) is the large telescope of the National Astronomical Observatory of Japan at the Mauna Kea Observatory on the island of Hawaii. From 1999 to 2005, its main mirror was the largest in the world.[1]

The telescope is named after the Pleiades star cluster.

History[change | edit source]

In September 1999, former-Princess Sayako of Japan dedicated the telescope.[2] For the dedication, an eyepiece was constructed so that Princess Sayako could look through it directly.[3]
