Stargazing Guide.
Discover why the Du Quoin area serves as a strategic corridor for IL observers. We combine community-vetted spots like Neckers Astronomy Observation Deck with professional NPS sky reports at Houchin's Field for a complete astronomical perspective.
Stargazing Logistics for Du Quoin
- STEP 1. Primary Staging Area: Neckers Astronomy Observation Deck. This is your most reliable community-vetted hub within a ~19.0 mile radius.
- STEP 2. Sky Quality Baseline: Classified as Class B (Rural). Use the instrumented 4 rating from Houchin's Field as your technical benchmark for the region.
- STEP 3. Local Support: Contact Astronomical Association of Southern Illinois for updated site access and group observation schedules.
- STEP 4. Observation Density: There are 5 recognized sites near Du Quoin offering varied horizons and atmospheric stability levels.
Du Quoin is positioned in a strategic 'Starlight Corridor.' It is far enough from the IL 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 Du Quoin
Observation in Du Quoin 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 Du Quoin Observers
Thermal equilibrium is key. Since Du Quoin temperatures can shift rapidly after sunset, allow your telescope mirrors at least 45 minutes to 'cool down' before attempting high-magnification work at Neckers Astronomy Observation Deck. This prevents 'tube currents' from blurring your view of Jupiter or Saturn. Scientific Context: While local conditions vary, the instrumented reading of Bortle 4 at Houchin's Field (179.3 miles away) remains the benchmark for regional sky quality.

Houchin's Field
Mammoth Cave NP
Local Relevance
The scientific findings at Houchin's Field provide Du Quoin residents with the most reliable data on regional atmospheric stability.
"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
For observers in Du Quoin, Log Cabins serves as the definitive baseline for high-altitude transparency and localized skyglow data.
"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"
