The Best Times for Stargazing in Seabrook

While Autumn offers the most consistent clear nights for Seabrook, wait for the 4-day window surrounding the New Moon each month for the deepest contrast. Since the sun sets early in the late Autumn months, you can often begin deep-sky imaging as early as 7 PM.

Expert Tips for Seabrook Observers

When observing from Rock Creek Park, try to position yourself facing away from the nearest major light dome. For Seabrook 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 4 at Harriet Tubman Underground Railroad NHP (53.0 miles away) remains the benchmark for regional sky quality.

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