Michigan's largest amateur star party.

Thank you for yet another wonderful star party! The 2023 twenty-first GLSG star party will be held from September 14 - 17, 2023. Registration will open in late spring of 2023. The 2024 star party is tentatively scheduled for September (coming soon), 2024. Thank you for twenty years of planets, galaxies, mud, prizes, fun, and dark skies! We've enjoyed every moment with you and are excited for the 2023 star party. Check out our Facebook page.

Mail-in registration is currently CLOSED. We expect it to open in late spring.

Location and dark skies are the main attraction of this star party. Gladwin, MI is a central location that provides excellent observing without traveling hours into Northern Michigan. Limiting magnitudes are estimated to be around 6.5 at zenith with some minor light domes from the cities of Mt. Pleasant and Midland, some 30 miles away. This is a star party for the astronomer who loves to observe and mingle with other astronomers. Some practical and interesting talks are scheduled to enhance your weekend experience.

The GLSG star party will be held at the River Valley RV Park in Gladwin, MI. Directions and more information about the star party can be found in the registration form.
