The Best Times for Stargazing in Ketchikan

Expert Tips for Ketchikan Observers

Don't underestimate the power of peripheral vision (averted vision). At sites near Ketchikan, 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 AK region. Scientific Context: While local conditions vary, the instrumented reading of Bortle 2 at Park entrance sign (264.1 miles away) remains the benchmark for regional sky quality.
