Explore the Night Sky

Join us & the San Antonio Astronomical Association for a night of celestial wonder!

Explore the night sky with the San Antonio Astronomical Association! We’ll be viewing and learning about Saturn and Jupiter along with many constellations and other planets. We’ll also look for star clusters, nebula, and much more. You can also learn the basics of telescope operation.

Bring your own telescope or binoculars or enjoy the sights from one of the SAAA’s telescopes.  Park in Parking Lot A and walk the short distance to Parking Lot C where the telescopes will be set up. Dress for the weather. Bring water, a snack if you like, and your own flashlight with a red lens cover.

Open to all ages; participants under 18 must be accompanied by a parent or guardian.

No reservations are required, no pets please.
