Expert Tips for Fairfield Observers
Don't underestimate the power of peripheral vision (averted vision). At sites near Fairfield, 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 CA region. Scientific Context: While local conditions vary, the instrumented reading of Bortle 6 at Hill SE of 4 corners (38.0 miles away) remains the benchmark for regional sky quality.
