The Best Times for Stargazing in Sammamish

Expert Tips for Sammamish Observers

When observing from Big Rock Park, try to position yourself facing away from the nearest major light dome. For Sammamish residents, this usually means looking toward the rural horizons of WA 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 Burroughs Mountain (50.6 miles away) remains the benchmark for regional sky quality.

Regional Perspective: Observers in Sammamish often prefer their local clearings over Newcastle for spontaneous stargazing, thanks to a shorter commute into the dark zones.
