• The Jorge Sahade Telescope (JS) is a Ritchey-Chrètien reflecting telescope built by
Boller & Chivens. The 40-ton telescope is supported by an
equatorial mount. It was installed in 1984 and began regular operations in 1987. It was originally purchased by UNLP in the 1960s. • The
Solar Submillimeter Telescope (SST) is a solar radio telescope design to observe
solar flares at two wavelengths in the
submillimeter range. It is a partnership of CASLEO and the Mackenzie Center for Radio
Astronomy and Astrophysics of Brazil. Several other organizations have also participated. The SST was installed in 1999 and began routine operations in 2001. • The Helen Sawyer Hogg Telescope (HSHT) is a classical
Cassegrain reflector built by Competition Associates and installed in 1971 at the
University of Toronto Southern Observatory, which was located at
Las Campanas Observatory in
Chile. In 1997 UTSO was shut down, and the telescope was loaned indefinitely to CASLEO, where it was installed in 1998. The telescope was dedicated to
Helen Sawyer Hogg before it was moved. • The Astrograph for the Southern Hemisphere (ASH) is a reflecting telescope on an
equatorial mount. It is a partnership of CASLEO and the Astrophysics Institute of Andalucía. • The Horacio Ghielmetti Telescope (THG) is a Schmidt-Cassegrain reflector made by
Meade Instruments attached to an equatorial mount. It is operated by CASLEO and the Institute of Astronomy and Space Physics of Argentina. • The HASTA (H-alpha Solar Telescope of Argentina) for full-disk monitoring of solar H-alpha activity at high resolution. ==Gallery==
