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 direct 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.
The guided tour begins at the summit of Mt. Locke. Visitors may drive their vehicles or ride the Observatory shuttle from the Visitor Center. Guides provide history of the Observatory and the large telescopes, including descriptions of the parts of the telescope, demonstrations of the telescope motions, etc. The tour continues to the summit of Mt. Fowlkes and the Hobby-Eberly Telescope (HET). At the HET, you'll learn more about that telescope's unique design and the current cutting-edge research done here. During Spring Break, Mt.

Please note that, other than what is described above for the Solar Viewing program, there is no viewing through telescopes during the Guided Tours.
From the start of the Solar Viewing to the end of the Guided Tour, the Daytime Programs typically run approximately 2.5 hours.
