Optical Layout The Observatory at Cordón Macón, in the remote Atacama region of northwestern Argentina.


The Transient Optical Robotic Observatory of the South, (TOROS) is being developed as a facility to detect and characterize transient astronomical phenomena including electromagnetic counterparts to gravitational wave sources. It will operate robotically and is expected to be fully operational in 2021.


Located at Cordón Macón in Salta Province, Argentina, 4660 m elevation.

Telescope, Corrector, and Filters

The telescope is a Planewave CDK24 (f/6.5 Corrected Dall-Kirkham)

Optical Layout

The PlaneWave CDK24 will be modified to include a tertiary mirror, three N-BK7 corrector lenses, a fold mirror, and filters (LSST g,r,i,z, and 550-950 nm broadband).


The TOROS detector is a STA1600LN a 10560 x 10560 pixel (9 μm) CCD with a 95.04mm x 95.04mm image area. Plate scale is 0.47”/px with a 1.9 square degree field of view.
