Expert Tips for Circleville Observers
Don't underestimate the power of peripheral vision (averted vision). At sites near Circleville, 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 OH region. Scientific Context: While local conditions vary, the instrumented reading of Bortle 5 at Blackrock Summit (244.9 miles away) remains the benchmark for regional sky quality.
