The Best Times for Stargazing in Sunnyside

Expert Tips for Sunnyside Observers
Don't underestimate the power of peripheral vision (averted vision). At sites near Sunnyside, 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 WA region. Scientific Context: While local conditions vary, the instrumented reading of Bortle 4 at Burroughs Mountain (83.2 miles away) remains the benchmark for regional sky quality.
