Victor Blanco
Cerro Tololo

The Blanco 4m telescope was commissioned in 1974. It is a near twin of the Mayall 4m telescope on Kitt Peak. With the advent of the SOAR 4.2 m telescope, under construction on Cerro Pach?n, it is the policy of the Observatory to develop the two telescopes to complement each other: wide field applications on the Blanco 4m and high resolution applications, which exploit the better image quality available over a more restricted field, on SOAR.
