The Best Times for Stargazing in Crofton
In MD, the transitional periods of early Spring often provide a stable atmosphere between weather fronts. For Crofton residents, this means less 'star twinkling' (scintillation) and a significantly steadier view for high-magnification planetary observation.
Expert Tips for Crofton Observers
Thermal equilibrium is key. Since Crofton temperatures can shift rapidly after sunset, allow your telescope mirrors at least 45 minutes to 'cool down' before attempting high-magnification work at Rock Creek Park. This prevents 'tube currents' from blurring your view of Jupiter or Saturn. Scientific Context: While local conditions vary, the instrumented reading of Bortle 4 at Harriet Tubman Underground Railroad NHP (48.7 miles away) remains the benchmark for regional sky quality.

"Setup camera on the west side of the pond on USFWS Refuge adjoining the park. Many local glare sources visible from the visitor center and administrative offices, as well as the visitor parking lot. We were able to turn off several closer lights on the pavilion and its adjoining grass parking area. A cold night with very clear skies after a cold front moved through. The Milky Way was visible from 25° above the horizon in the north to 20° above horizon in the south. Not too much detail but M31 (Andromeda Galaxy) was visible to the naked eye and overall this night sky provides good opportunities for public observing."
