Target new moon phases for darkest skies and longest tours. Book ahead for star parties at remote sites like McDonald or Kitt Peak, as slots fill months out. Check weather forecasts rigorously, prioritizing dry, calm nights over weekends.
Arrive early for daytime exhibits on historic discoveries like Pluto at Lowell. Follow guided protocols to avoid disrupting research telescopes. Dress in layers for chilly mountaintop evenings, even in desert regions.
Practice basic star apps for context, but rely on on-site experts for deep-sky objects. Rent facility telescopes to skip gear hassles. Explore nearby trails for independent dusk views if tours end early.
