The Best Times for Stargazing in Kentfield

Expert Tips for Kentfield Observers
Don't underestimate the power of peripheral vision (averted vision). At sites near Kentfield, 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 (4.0 miles away) remains the benchmark for regional sky quality.
