The Best Times for Stargazing in Portland

Expert Tips for Portland Observers
When observing from cruise ship, try to position yourself facing away from the nearest major light dome. For Portland residents, this usually means looking toward the rural horizons of OR 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 (91.5 miles away) remains the benchmark for regional sky quality.
