Next GMARS Star Party

June 7th – 9th

Get ready for the summer night sky! The Milky Way will be best-positioned around midnight, so get ready to enjoy the photons from all the objects in Sagittarius, Scorpius, Ophiuchus, Cygnus, and more!

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.
