The Best Times for Stargazing in Seaside
For the best experience, target the late-night window between 1 AM and 4 AM in Seaside. 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 Seaside Observers
Don't underestimate the power of peripheral vision (averted vision). At sites near Seaside, 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 OR region. Scientific Context: While local conditions vary, the instrumented reading of Bortle 3 at Plummer Peak (116.7 miles away) remains the benchmark for regional sky quality.
