General Admission allows you to explore the Visitors Center, including the exhibit gallery and gift shop. Self Guided Tours of our largest telescope, the 10-meter Hobby-Eberly Telescope, are available from 12 p.m. to 5 p.m. Tuesday-Saturday as part of General Admission. See the "Learn More..." drop-down text below for more information on what parts of the facility are available to the public. General Admission passes can be purchased in person when you arrive at the Visitors Center.
General Admission provides access to the Visitors Center and self guided tours only. To visit the research areas, make reservations for a Guided Tour. Both the Guided Tour and Evening Programs passes include General Admission.
The Visitors Center operates a set of specially filtered telescopes equipped with cameras that allow us to bring live, safe views of the Sun into our theater. Knowledgeable guides present history of the Sun, its formation, and what we expect the Sun to do over the next 5-6 billion years. Your guide directs the telescope to view the Sun and various surface features. On not so clear days, video and stills are used. This is typically a 45-50 minute program.
Join a Guided Tour for an up-close look at large research telescopes at McDonald Observatory in West Texas.
