The Best Times for Stargazing in Highlands Ranch

Expert Tips for Highlands Ranch Observers
Don't underestimate the power of peripheral vision (averted vision). At sites near Highlands Ranch, 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 CO region. Scientific Context: While local conditions vary, the instrumented reading of Bortle 3 at Florissant Fossil Beds National Monument (46.6 miles away) remains the benchmark for regional sky quality.
