Answers to the FAQs
An up-to-date listing of all accommodations in the Fort Davis area is available through the Fort Davis Chamber of Commerce web site.
No, Star Parties are held rain or shi ... er ... well ... clear skies. If it's too cloudy/rainy/windy/dusty/humid (we get strange weather up here sometimes) to do our observing, we conduct indoor programs instead. These can include, but are not limited to, "virtual" Moon tours, spectroscopy demonstrations (an activity designed to give our visitors a better understanding of how astronomers learn about the universe), "virtual" solar system tours, presentations on satellite viewing, etc. Occasionally, research astronomers will join us to provide talks on their current research programs. Because we have such a wide array of interesting, educational programs to present on these nights, your Star Party passes are not refundable on the basis of inclement weather.
Directions to the Observatory from the major highways in the area are available in the Visiting section of our site.
Descriptions and schedules for all of our programs are available in the Programs section of our site.
Generally speaking, yes ... and please spend a little more time making your plans. For visiting our research areas, your best plan is to join us for one of our twice-daily guided tours. During the tour, you'll have access to an elevator at the 107-inch dome that would otherwise be unavailable. If you need to drive your own vehicle to the top, ask the staff at the Visitors Center Information Desk for a special parking permit to be able to park right next to the dome.
For the most part, our other activities are accessible without special preparations. Solar Viewings are conducted in our multimedia theater at the Visitors Center using remote telescopes and video equipment. Most visitors find that getting to the eyepieces of our telescopes during Star Parties requires only moderate assistance (the possible exception being our 22-inch telescope which sometimes requires the ability to climb several steps).
Our 36" Special Viewing Night is NOT wheelchair accessible. If you're considering joining this program and have accessibility concerns, please call our Visitors Center at (432) 426-3640.
In late summer of 2010, we unveiled a spectacular new telescope at our Visitors Center which is specifically designed for wheelchair access.
Officially the Observatory/Visitors Center is closed on Thanksgiving Day, Christmas Day, and New Years' Day, and we don't conduct Star Party programs on Christmas Eve or New Year's Eve. The Gift Shop is closed one day each year near the end of August in order to conduct an annual inventory. If you are wondering if this may happen on the day you're planning to visit, feel free to call us (432-426-3640). Other than these times, the Center is open 10:00 A.M. to 5:30 P.M. every day.
Our web site is designed to provide the most current information in the most timely way. Our printed information is much more generic and can be obtained by calling the Visitors Center at 432-426-3640.
Tours of our facility are conducted every day at 11:00 A.M.. and 2:00 P.M. which is the best way to see the research areas. Nighttime access is generally restricted to our Visitors Center Public Observatory where our three-times-per-week evening Star Parties are conducted.
Generally speaking, no, although you're strongly encouraged to make online reservations for our regular weekly programs, the Guided Tours, Solar Viewings, Twilight Programs, and Star Parties. If you plan to purchase your passes on person at the Visitors Center, you should plan to arrive no less than 20 - 30 minutes early (earlier during peak periods, like March, June, July, and holidays typically), as passes are limited in number for all programs except for the Star Party. The only programs that do require reservations (typically months in advance) are the occasional Special Viewing Nights in the 107" and 36" research telescopes.
There's no easy way to answer that one ... it depends on what you want to do or see. To see the research areas, you'll want to visit between 10:00 A.M.. and 4:30 P.M. daily (particularly, the Guided Tours.) For nighttime telescope viewing, our Star Parties are your best bet. If you're asking for the best time of year to visit us, typically Autumn brings us our most consistently clear skies. Over the next few years, Spring/Summer will be the best time for seeing Saturn, and Winter/Spring are best for Jupiter. If you plan on attending a Star Party, consider the phase of the Moon. With the Moon at any phase between several days before First Quarter and 3 or 4 days past Full, bright moonlight limits our ability to observe faint objects but, of course, gives us great views of the Moon itself. You can see a calendar of Moon phases at StarDate Online to help you make your plans.
As much as we'd like to start the Star Parties in the Summer at an earlier time, it is just not dark enough to do so until nearly 10:00 P.M. The Observatory is located very far west in the Central Time zone, so while we are in the same time zone as Houston, Dallas, San Antonio, and Austin, the times of sunrise and sunset are very different. In fact, the Sun sets at the Observatory almost an hour later than it does in Houston.
Having a telescope is not necessary ... we've got quite a few. Come on up and join us. All you really need is a desire to learn about the night sky. Binoculars can help as well (but, once again, they aren't necessary.) If you have a telescope you'd like to bring along ... that's fine. Keep in mind, though, that if you set up your scope during the public Star Party people WILL want to look through it and we'll ask you to accommodate their requests. So, if you'd rather not have people near your expensive telescope, you can always set up later.
Yes, by all means, feel free to give us a hand. As long as you're willing to let others look through your telescope and answer the questions they may have about it, you're more than welcome to set up with us. If you'd rather not have people around your expensive telescope, you're welcome to do your observing after the public Star Party. The Observatory is NOT a campground, however, so if you're here, you should be observing. After you're finished observing, you must remove your equipment and leave the facility ... no camping (tent, RV, or otherwise) is allowed on Observatory grounds. If you can work with these rules, we'll be happy to accommodate you.
Our online reservation system gives an up-to-date status on the availability of all of our programs. If the status is showing in red, it means the program is sold out .. green and there are passes available. If the program you're interested in is showing as sold out, either pick a different date or check back later for a change in the availability. You might also find our regular Star Party programs to be quite enjoyable. While we do occasionally receive requests for cancellations, such requests are rare .. particularly for the various Special Viewing Nights. We do not maintain call-back lists for our programs.
There isn't a "nearby" airport. For private aviation there are airstrips in Marfa and Alpine (both about 40 miles from the Observatory). Both have car rental services. For commercial flights, the nearest airports are in El Paso (185 miles) and Midland-Odessa (170 miles). Although you can count on roughly 2.5 to 3 hour drives from either, when driving from El Paso you'll lose an hour going from Mountain time (El Paso) to Central time (McDonald).
Not at the moment - our StarDate Café in the Visitors Center is temporarily closed. The Cafe is currently offering sodas, coffee, and various snacks (chips, cookies, etc.) only.
There are many restaurants in Fort Davis offering a reasonably wide variety of food. There are several roadside picnic tables nearby on Hwy 118 (two towards Fort Davis, about 1/2 mile and 2 miles, and another about 1/2 mile towards Kent.) A very nice picnic area, called the Lawrence E. Wood Roadside Rest Area, is about 8 miles northwest of McDonald towards Kent along Hwy 118.
No, the Observatory is a University of Texas research facility and is not associated with the State/National Park systems. Overnight camping/RVing on Observatory grounds is NOT permitted. The are a number of places in and around Fort Davis that do offer camping/RVing. Please check the official Fort Davis website for a list of area accommodations.
Private programs must be arranged at least 40 days prior to the date you are requesting.
Groups are more than welcome to join us for any of our programs, and we'd appreciate advance notice about which programs your group is interested. Many times we can offer private activities that may better suit your group's needs. If you have any questions concerning your group's visit, please feel free to contact us.
The Aurora Borealis is only rarely seen at latitudes below 35 degrees. The Observatory is at 30 degrees north, so seeing the aurorae here is quite rare ... happening perhaps only a half of a dozen times every solar cycle (approx. 11 years.) Typically, solar and geomagnetic activity must be at an extreme maximum for us to see any activity at all and is difficult to predict at best. An excellent resource for learning more about such activity is the NASA supported site called SpaceWeather.com.
