Next GMARS Star Party

February 17th – 19th

It'll soon be time for another winter star party at GMARS! Bring your sweetheart (it IS the first weekend after Valentine's Day, after all) and join us for the dark skies, starbecue, and camaraderie. It's time to relax and recharge under the night sky!

🌵 🌞 🌚 ⭐ 🔭

Enjoy great telescopic views of planets, star clusters, nebulae, galaxies and more! Don't forget to come prepared for chilly temperatures! GMARS star parties start Friday afternoon/evening and wrap up on Sunday morning.
