Join a Guided Tour for an up-close look at large research telescopes at McDonald Observatory in West Texas.
Your purchase of a Daytime Pass is the ticket to many great activities. Inside the Frank N. Bash Visitors Center, explore the Decoding Starlight exhibit and enjoy a Solar Viewing Program (typically 45-50 minutes) in our theater featuring live (weather dependent) telescope images of our nearest star, the Sun, including views of such solar features as sunspots, prominences, and flares, every day of the week at 11 a.m. and 2 p.m. For insight into the workings of a professional scientific research facility, take an approximately 90-100-minute tour with a knowledgeable guide to one of our large research telescopes immediately following the Solar Viewings. Tours often sell out, especially on holiday weekends and during summer months, so we strongly recommend you reserve discountedtickets online in advance (see below). Daytime passes may be purchased online (assuming availability) until midnight before the program. Check the calendar for program offerings and start times for the date you plan to visit.

The system defaults to one adult pass. If you don\'t need that pass, click the number field and select zero.
If you\'re 65 or over and want the senior discount, choose the \"Snr (65+)\" pass only. There is no need to purchase both an adult and a senior pass ... by definition, if you\'re a senior, you\'re already an adult. Adding the senior pass does not discount the adult pass ... it just adds another pass to your purchase and you\'ll end up purchasing more than you need.
Be sure to click on the \"Book\" button as your final step in making your reservation. Failure to click the \"Book\" button will result in no reservations being made.
