The Best Times for Stargazing in Cottleville
Observation in Cottleville is most rewarding during the Summer months. During this time, the colder air masses over the Midwest region often result in significantly higher transparency, allowing you to see objects like the Andromeda Galaxy or Orion Nebula with much more definition.
Expert Tips for Cottleville Observers
If you're visiting Stacy Park, bring a pack of chemical hand-warmers and rubber-band them to your eyepiece or camera lens. This acts as a 'budget' dew heater, which is essential for the humid nights often found in MO during the peak viewing seasons. Scientific Context: While local conditions vary, the instrumented reading of Bortle 4 at Houchin's Field (270.0 miles away) remains the benchmark for regional sky quality.

Houchin's Field
Mammoth Cave NP
Local Relevance
For observers in Cottleville, Houchin's Field serves as the definitive baseline for high-altitude transparency and localized skyglow data.
"A very calm, humid and clear night. 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. Limiting magnitude found in Pegasus."
Log Cabins
Fort Donelson NB
Local Relevance
Cottleville enthusiasts typically use the instrumented readings from Log Cabins to calibrate their deep-sky expectations for the area.
"SQM of 20.47 at 2035 local time. Only fair transparency and seeing. Some fast moving clouds. High humidity. Milky Way visible from 20 degrees above north horizon. Great rift visible, Saggitarius cloud not easily visible, Scutum cloud not visible. Milky Way about 10-12 degrees wide, but faint and no fine details. To the NW a blue white light dome easily seen. Due East is the Clarksville lightdome almost 25 degrees high and 15 degrees wide. Core is bright. Adjacent to the light dome is a spotlight (which we determined was coming from the cemetary here in FODO park). To the West and Southwest is another lightdome fainter than Clarksville, but brighter than the Milky Way"
