Expert Tips for Jefferson Observers
Don't underestimate the power of peripheral vision (averted vision). At sites near Jefferson, 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 LA region. Scientific Context: While local conditions vary, the instrumented reading of Bortle 5 at Horn Island (91.2 miles away) remains the benchmark for regional sky quality.
