Expert Tips for Nashua Observers
When observing from Phillips Exeter Academy Grainger Observatory, try to position yourself facing away from the nearest major light dome. For Nashua residents, this usually means looking toward the rural horizons of NH 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 5 at Province Lands VC (80.4 miles away) remains the benchmark for regional sky quality.
