The 2.7-m (107-inch) Harlan J. Smith Telescope, is the largest telescope on Mt Locke. The University of Texas at Austin operates the facility through the support of the state of Texas and offers time at no cost to users. Four instruments are currently available for use on the telescope, though only one instrument can be mounted at a time. The instruments are scheduled for use in blocks based on proposal selection and science scheduling constraints.
Remote observing is available at this facility for UT Austin prospers only. Classical observing is available to other proposers, please note that UT Austin proposals are prioritized over others.
