The Best Times for Stargazing in East Pasadena

Expert Tips for East Pasadena Observers
Don't underestimate the power of peripheral vision (averted vision). At sites near East Pasadena, 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 7 at Tuna Canyon Park (30.9 miles away) remains the benchmark for regional sky quality.
