Next Star Party

July 13th & 14th

We won't sugarcoat it... It's hot in the desert now. But it's absolutely beautiful and comfortable at night! And the house is air-conditioned if you need an escape from the sun.

Join us at GMARS for our regular monthly star party. The Milky Way is still in good position for those wide landscape night shots!

GMARS star parties start Friday afternoon/evening and wrap up on Sunday morning. Be sure to join us for the potluck Star-B-Q on Saturday afternoon (roughly 60-90 minutes before sun down). We provide the dogs, burgers and fixings. You provide a sidedish, dessert or beverages!
