The Best Times for Stargazing in Four Corners

While Spring offers the most consistent clear nights for Four Corners, wait for the 4-day window surrounding the New Moon each month for the deepest contrast. Since the sun sets early in the late Spring months, you can often begin deep-sky imaging as early as 7 PM.

Expert Tips for Four Corners Observers

When observing from verified local spots, try to position yourself facing away from the nearest major light dome. For Four Corners residents, this usually means looking toward the rural horizons of MT to capture the lowest magnitude stars that are normally invisible from the city center. Scientific Context: While local conditions vary, the instrumented reading of Bortle 2 at Frog Rock (57.5 miles away) remains the benchmark for regional sky quality.

Regional Perspective: If you're traveling from Livingston, the 30.2-mile trip to Four Corners is a justified detour for anyone seeking slightly clearer atmospheric 'seeing'.
