HEALTH & SAFETY AT MCDONALD OBSERVATORY ...

What We’re Doing to Help Keep You Safe
• We limit the number of visitors in programs. All areas of the Visitors Center, including exhibits, restrooms, and high-touch areas, are cleaned regularly. Hand sanitizing stations are available throughout the Visitors Center. Air purifiers are in use throughout the building. We encourage staff and visitors to follow all applicable CDC guidelines for mask wearing and social distancing.
• While we don't enforce social distancing in our public areas, to help prevent the spread of COVID-19, we encourage visitors to distance their group from others while on site. For our indoor programs (Guided Tours and cloudy Star Party evenings), it's not always possible to socially distance. Please use your best judgement and the available medical evidence.

We will happily reschedule or refund your passes with no charges.
• Use hand sanitizer, which will be available at stations throughout the building.

A self-guided tour map of both summits is available at teh Visitors Center an provided with General Admission. At the top of Mt. Locke, the views off to the east, south, and southwest can be stunning on a clear day. Restrooms are available at the 107" dome. There are also several informative short videos available for view in the ground floor lobby of the 107" dome. Currently, no other part of the 107" dome is accessible to the public except on the guided tour. The 82" dome is not accessible to the public.

At the summit of Mt. Fowlkes, you can see the largest telescope in North America and the 2nd largest in the world, the Hobby-Eberly Telescope (HET). The George T Abell Gallery at the HET features informative videos explaining the Hobby-Eberly Telescope Dark Energy Experiment (HETDEX). Public restrooms are also available in the HET gallery. A large panoramic window allows up-close views of this unique telescope.

Solar Viewing:

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.

Guided Tours:

Join a Guided Tour for an up-close look at large research telescopes at McDonald Observatory in West Texas.

A Guided Tour Pass includes access to the exhibit gallery and gift shop inside the Visitors Center and a guided tour of our large research telescopes (approximately 90-120-minutes). Check the calendar for program offerings and start times.

The Guided Tours begin in the Visitors Center with a brief introduction. Then the group heads up Mount Locke to the 107" Harlan J. Smith telescope dome. Visitors may drive their vehicles or ride the Observatory shuttle, although our shuttle service is currently prioritized for those driving large RV’s or with mobility/respiratory issues. 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.

These are the typical daytime activities. We occasionally alter the content or order to accommodate research activities or large numbers of visitors, or severe weather at our location. Please note that there is no viewing through telescopes during the Guided Tours.

The Guided Tour typically runs approximately 1.5 - 2 hours. Please arrive on time for your Guided Tour, as refunds are not available for those who arrive after the tour group has left the Visitors Center.

The 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.

Programs may be cancelled at any time due to weather or public health concerns.
