10 m Caltech Submillimeter Observatory

McDonald has an agreement with the California Institute of Technology for 10% of the nights on the 10m CSO submillimeter telescope at Mauna Kea, Hawaii.

South African Large Telescope (SALT)

Based on the design of the HET, SALT was inaugurated November 10, 2005, and is undergoing Performance Verification. The University of Texas will receive 5% of the telescope's observing time.

Non-UT Research Facilities Hosted at McDonald

Las Cumbres Observatory Global Telescope

McDonald hosts one of the nodes of the Las Cumbres Observatory Global Telescope and receives 15% of the telescope time on the global network. The first 1m telescope in the network achieved first-light at McDonald on March 31, 2012.

1.2 m MONET Telescope

McDonald hosts one of the two robotically controlled telescopes of the MONET project. The twin is located in South Africa. Installation in West Texas began in November 2005. The Observatory will likely receive a 10-15% share of each instrument.

20" Telescope

The observatory hosts a 20" telescope for Boston University's Imaging Science program.
