The Best Times for Stargazing in Campbelltown

Expert Tips for Campbelltown Observers
Don't underestimate the power of peripheral vision (averted vision). At sites near Campbelltown, 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 PA region. Scientific Context: While local conditions vary, the instrumented reading of Bortle 6 at Caboose Farm (65.0 miles away) remains the benchmark for regional sky quality.
