The observatory is named in honor of Mr. Curtis Torrey Vaughan Jr., longtime successful businessman, philanthropist, and local amateur astronomer in the San Antonio Area. As a result of his interest in astronomy, he was involved for many years with the McDonald Observatory in Fort Davis, Texas and served as Chairman of the McDonald Observatory Board of Visitors - University of Texas at Austin. The telescope in our observatory once belonged to Mr. Vaughan, a research grade 16" Meade LX200 Advanced Coma Free telescope. It was donated to UTSA for scientific research for physics and astronomy students. It is currently being used in tracking asteroids and minor orbiting bodies within our solar system for orbital tracking.

Open Observatory Nights

The observatory hosts First Friday Stargazing beginning at sunset every first Friday of the month (weather permitting), and for Friday Nights Celestial Lights, which occurs every Third Friday of the month when school is in session in the Spring and Fall semesters.

Additionally, the observatory is now open every Wednesday evening beginning at sunset throughout the year (weather permitting) to all current UTSA students who wish to learn more about astronomy, how to operate a telescope, or may need help with an astronomy class assignment.

The Telescopes

Beginning in early 2015, a complete overhaul of the facilty began with the goal to increse public outreach to the community, as well and create a top-tier astronomical research station for astronomy related science . The observatory has a wide variety of telescopes on hand for use in both public outreach and for astronomical research.

The following telescopes are used at the observatory:

16-inch Meade LX200 Advanced Coma Free Telescope

16-inch Meade LX200 GPS Schmidt-Cassegrain Telescope

2 8-inch Meade LX200 Advanced Coma Free Telescopes

15-inch Obsession Newtonian Reflector Telescope

13-inch Coulter Odyssey Reflector Telescope

10-inch Orion XT10 Newtonian Reflector

2 Lunt Hydrogen Alpha Solar Telescopes

Lunt Calcium-K Solar Telescope


The observatory is now embarking on a program to teach UTSA students to operate the observatory telescopes and to present astronomy related programs to the public.
