Expert Tips for New Castle Observers

When observing from Valley Forge National Historical Park, Model Airplane Field, try to position yourself facing away from the nearest major light dome. For New Castle residents, this usually means looking toward the rural horizons of DE 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 Harriet Tubman Underground Railroad NHP (89.6 miles away) remains the benchmark for regional sky quality.

Regional Perspective: New Castle is situated just 6.9 miles from Edgemoor, but its local horizon often provides a more stable viewing experience for planetary targets.
