Texas Star Party

Star parties are better together. Check schedule, message friends, track your observing list, and find your way around Prude Ranch during TSP 2026 (May 10-17).

The official companion app for the Texas Star Party at Prude Ranch, Fort Davis, Texas — one of the premier dark-sky astronomy gatherings in North America.

WHY INSTALL • Keep the event schedule in your pocket • Message fellow attendees and coordinate observing sessions • Check off objects from classic observing lists (Herschel 400, Messier, and TSP-curated lists) • Find vendors, speakers, and amenities around the ranch • See live weather and seeing conditions for the field • Get notified about special events, contests, and your volunteer shifts

NIGHT-VISION MODE Critical for dark-adapted observing. A deep-red night mode keeps screen light from ruining your vision (and your neighbors').
