Next GMARS Star Party

December 8th – 10th

Our next star party returns to GMARS! After the annular eclipse and Nightfall, events that took most members away from GMARS, we're happy to return to our beloved dark sky site for our next star party!

Bring a side dish to share at the Star-B-Q if you'll be participating.

🌞 🌚 🏜 ⭐ 🔭

Recharge under the night sky, and enjoy great telescopic views of planets, star clusters, nebulae, galaxies and more! GMARS star parties start Friday afternoon/evening and wrap up on Sunday morning.
