Expert Tips for Temecula Observers
When observing from Pioneertown Mountains Preserve, try to position yourself facing away from the nearest major light dome. For Temecula residents, this usually means looking toward the rural horizons of CA 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 6 at Main Ridge Road (16.0 miles away) remains the benchmark for regional sky quality.
