Expert Tips for Chillicothe Observers
When observing from The Lewis Observatory, Ohio University Zanesville, try to position yourself facing away from the nearest major light dome. For Chillicothe residents, this usually means looking toward the rural horizons of OH to capture the lowest magnitude stars that are normally invisible from the city center. Scientific Context: While local conditions vary, the instrumented reading of Bortle 5 at Blackrock Summit (241.8 miles away) remains the benchmark for regional sky quality.

Blackrock Summit
Shenendoah NP
Local Relevance
For observers in Chillicothe, Blackrock Summit serves as the definitive baseline for high-altitude transparency and localized skyglow data.
"Exceptionally clear skies and air for this eastern US site. Very dry air with some moderate winds provided visibility of 50-75+ miles during the day. At night the horizon is almost completely illuminated by cities, small towns and rural farms and ranches. Some very bright direct glare sources in the cities of Harrisonburg and Fishersville (Hospital?). The Milky Way was visible to the horizon in the SW and obscured at about 25 degrees above horizon in the NE. Very good detail in Cygnus near the zenith. Washington D.C. light dome easily visible to the ENE. With some lengthy dark adaptation, this observer was able to see 6.7 magnitude star in Pegasus."
Houchin's Field
Mammoth Cave NP
Local Relevance
For observers in Chillicothe, Houchin's Field serves as the definitive baseline for high-altitude transparency and localized skyglow data.
"Dewfall occurred during data collection, however dew heater prevented lens fog. Multiple light domes evident from site, as well as a continuous glow along horizon in all directions. Airglow was present. Andromeda galaxy easily visible, Beehive (Pegasus) visible with medium effort. Prominent dust lanes in Milky Way visible at zenith, but not below ~50 degrees."
