Friday and Saturday Public Viewing
Fall semester schedule
November 7 to December 6
7:00 - 9:00 p.m.
(No viewing November 28 and 29 due to the Thanksgiving holiday)
Please note - there will be no public viewing at the Painter Hall Telescope on
nights when there is a UT home football game. Not all games have a start time set as of the
start of the season, so please check the schedule before planning your visit.
Every Friday and Saturday while UT is in session the Department of Astronomy hosts free viewing on the Painter Hall Telescope. Both Friday and Saturday nights are open to the general public. Painter Hall is located at the corner of 24th street and Inner Campus Drive, just to the north of the UT Tower.

Please call 512-232-4265 for weather cancellation information. (This line is updated approximately 30-45 minutes before the scheduled start time.) To get to the telescope, take the elevator to the 5th floor and exit to the left. Follow the 5th floor hallway to the end and take the stair case through the double doors on the left. Once you reach the 6th floor, go to your right and follow the signs up to the telescope.
If you are interested in bringing a small group of 15 or fewer, you may come to a public viewing night without prior arrangements. If you plan on bringing a group of more than 15, please notify Lara Eakins at least two weeks in advance to avoid having too many groups show up on the same evening. Please note: we do not do private events for groups or individuals.
Public viewing nights occur throughout the year while the unversity is in session. Typically spring semester viewing runs from late January to early May, summer sessions viewing runs from early June to mid-August, and fall semster viewing runs from early September to early December. The other telescope on campus is located at Robert Lee Moore Hall and is open on Wednesdays.
History of the 9-inch telescope
The 9-inch telescope has a long history with the University. The lens in the telescope is actually older than the tube, mount and dome and was ground a little before the turn of the 20th century by the John A. Brashear company -- one of the finest lens makers of the time. The tube and mount were made by the Warner and Swasey Company of Cleveland and was placed in Painter Hall when the building was constructed in the early 1930s. The dome appears green from the outside because of its high copper content, which oxidizes to a patina similar to the color seen on the Statue of Liberty. The inside has been painted but in areas where the paint has chipped, the brilliant original copper can be glimpsed. Unlike most modern telescopes, no electricity is required to operate the clock drive on the telescope. Instead, the drive is wound up to raise a weight which will drop throughout the evening and turn the drive gears.
