The Southern African Large Telescope (SALT) is a 10-meter segmented optical reflector telescope at the Sutherland Observing Station of the South African Astronomical Observatory (SAAO) in South Africa, in operation since 2005. The primary mirror consists of 91 1-meter segments. The primary mirror is spherical, I'm guessing for much easier construction, and an optical system corrects for the resulting spherical aberration.

SALT's overall design was based on the Hobby-Eberly Telescope (HET), but with some newer technology.
