The Best Times for Stargazing in Chillum

Expert Tips for Chillum Observers

When observing from Rock Creek Park, try to position yourself facing away from the nearest major light dome. For Chillum residents, this usually means looking toward the rural horizons of MD 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 Murphy-Chambers Farm (48.2 miles away) remains the benchmark for regional sky quality.

Regional Perspective: Observers in Chillum often prefer their local clearings over Adelphi for spontaneous stargazing, thanks to a shorter commute into the dark zones.
