Cerro Tololo Inter-American Observatory
The Cerro Tololo Inter-American Observatory ( CTIO ) is a complex of astronomical telescopes and instruments on Cerro Tololo, about 80 km east of La Serena in Chile at an altitude of 2200 meters. The CTIO's IAU code is 807.
The observatory has a number of reflector telescopes . The main instrument on the Cerro Tololo is that
- 4 m Victor M. Blanco telescope. Instruments available for this telescope are:
- 8K image sensor,
- Hydra-CTIO spectrograph , with which up to 138 objects can be examined simultaneously,
- and a classic RC spectrograph.
There are also some smaller telescopes, the so-called "smarts". In order of the diameter of the main mirror, these are:
- 1.5 m to which the "CPAPIR", a wide field IR image sensor, or an RC ( Cassegrain ) spectrograph can be connected,
- 1.3 m, with "ANDICAM" (image sensor for simultaneous recordings in the visible and infrared ),
- 1.0 m, with a 4K visible light image sensor and
- 0.9 m, with a 2K image sensor for visible light.
This is located on Cerro Pachòn , around 500 meters higher (coordinates: ), 10 km away
- 4.1 m Southern Astrophysical Research (SOAR) telescope , and one of the two
- 8.1 m Gemini telescope .
