Next GMARS Star Party

March 17th – 19th

Winter is almost over — Join us for the last GMARS star party before spring! Dress warm as nights are still quite chilly. Be sure to bring a side dish to share if attending the Saturday Star-B-Q!

🌵 🌞 🌚 ⭐ 🔭

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.
