The Víctor M. Blanco Telescope, also known as the Blanco 4m, is a 4-metre aperture telescope located at the Cerro Tololo Inter-American Observatory, Chile on the summit of Mt. Cerro Tololo. Commissioned in 1974 and completed in 1976, [1] the telescope is identical to the Mayall 4m telescope located on Kitt Peak. [2] [3] [4] In 1995 it was dedicated and named in honour of Puerto Rican astronomer Víctor Manuel Blanco. [5] It was the largest optical telescope in the Southern hemisphere from 1976 until 1998, when the first 8-metre telescope of the ESO Very Large Telescope opened.
Currently the main research instrument used at the telescope is the Dark Energy Camera ( DECam), the camera used in the Dark Energy Survey. DECam saw its first light in September 2012. [6] [7]
The Mosaic II camera was used at this CTIO 4-m telescope in the southern hemisphere since 1999. [8] This was a development of the KNPO Mosaic camera installed in 1998 in the northern hemisphere. [8] These cameras were used for various astronomical surveys, and were noted for their success. [8]
