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.
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. Fowlkes & the HET are a
We occasionally alter the content or order to accommodate research activities or large numbers of visitors (e.g., during Spring Break, during which we offer additional programs which only visit one of the large research telescopes). While the Solar Viewing typically takes place much as described above, the content of the tour may take place in somewhat altered order, or the Hobby-Eberly Telescope may be self-guided only. Please note that, other than what is described above for the Solar Viewing program, there is no viewing through telescopes during the Guided Tours. These are the typical daytime activities.
From the start of the Solar Viewing to the end of the Guided Tour, the Daytime Programs typically run approximately 2.5 hours.
Visitors Center is accessible via wheelchair. The 107" Telescope dome floor is accessible via elevator which is available only on the guided tours. The summit of Mt. Locke has some steep grades. Inquire at the Visitor Center for a parking pass when participating in the guided tour. The HET's George T. Abell gallery at the summit of Mt. Fowlkes is accessible.
Passes for the Solar Viewing-only may also be purchased for those who may be on a tight time-schedule.
Self Guided Tours of our largest telescope, the 362-inch Hobby-Eberly Telescope, are available at no charge from 10 a.m. to 5 p.m. daily. See the drop-down text below for more information on what parts of the facility are available to the public.
