Expert Tips for Glenn Dale Observers
Don't underestimate the power of peripheral vision (averted vision). At sites near Glenn Dale, looking slightly to the side of a faint nebula will reveal much more detail than looking directly at it, especially when dealing with the Class 5+ suburban skies of the MD region. Scientific Context: While local conditions vary, the instrumented reading of Bortle 4 at Harriet Tubman Underground Railroad NHP (51.4 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. The light dome from the greaer Washington D.C. area on over to Baltimore extended about 30° above the horizon. Norfolk Virginia was visible to about 20° above the horizon and Salisbury and Ocean City were easily visible to the east. The lights of Cambridge and Easton illuminated a few remaining clouds to the NNE. SQM zenith brightness reading of 20.59."
