Expert Tips for Collinsville Observers
When observing from Gateway Arch, try to position yourself facing away from the nearest major light dome. For Collinsville residents, this usually means looking toward the rural horizons of IL 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 Houchin's Field (235.8 miles away) remains the benchmark for regional sky quality.
