The Best Times for Stargazing in Cahokia Heights
For the best experience, target the late-night window between 1 AM and 4 AM in Cahokia Heights. 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 Cahokia Heights Observers
Don't underestimate the power of peripheral vision (averted vision). At sites near Cahokia Heights, 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 IL region. Scientific Context: While local conditions vary, the instrumented reading of Bortle 4 at Houchin's Field (240.0 miles away) remains the benchmark for regional sky quality.
