The Best Times for Stargazing in Palo Alto
For the best experience, target the late-night window between 1 AM and 4 AM in Palo Alto. This is when local industrial lighting and residential 'sky glow' is at its minimum, and the most prominent Winter constellations are directly overhead at the zenith.
Expert Tips for Palo Alto Observers
Don't underestimate the power of peripheral vision (averted vision). At sites near Palo Alto, 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 (41.1 miles away) remains the benchmark for regional sky quality.
