- STEP 4. Observation Density: There are 5 recognized sites near O'Fallon offering varied horizons and atmospheric stability levels.
O'Fallon is positioned in a strategic 'Starlight Corridor.' It is far enough from the MO metro glare to allow for deep-sky imaging, yet serves as a convenient staging area for the deeper Class 4 skies found at Houchin's Field.
The Best Times for Stargazing in O'Fallon
For the best experience, target the late-night window between 1 AM and 4 AM in O'Fallon. 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 O'Fallon Observers
Don't underestimate the power of peripheral vision (averted vision). At sites near O'Fallon, 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 MO region. Scientific Context: While local conditions vary, the instrumented reading of Bortle 4 at Houchin's Field (273.8 miles away) remains the benchmark for regional sky quality.
