The Best Times for Stargazing in Sterling

While Spring offers the most consistent clear nights for Sterling, 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 Sterling Observers

When observing from Jackson Lake State Park, try to position yourself facing away from the nearest major light dome. For Sterling residents, this usually means looking toward the rural horizons of CO 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 4 at Summit Scotts Bluff National Monument (88.1 miles away) remains the benchmark for regional sky quality.

Regional Perspective: Sterling is situated just 34 miles from Brush, but its local horizon often provides a more stable viewing experience for planetary targets.
