Expert Tips for Potomac Observers
If you're visiting Rock Creek Park, bring a pack of chemical hand-warmers and rubber-band them to your eyepiece or camera lens. This acts as a 'budget' dew heater, which is essential for the humid nights often found in MD during the peak viewing seasons. Scientific Context: While local conditions vary, the instrumented reading of Bortle 6 at Murphy-Chambers Farm (36.7 miles away) remains the benchmark for regional sky quality.
