- STEP 1. Primary Staging Area: Jim Edgar Panther Creek State Fish & Wildlife Area. This is your most reliable community-vetted hub within a ~28.4 mile radius.
- STEP 2. Sky Quality Baseline: Classified as Class C (Suburban). Use the instrumented 6 rating from Log Cabins as your technical benchmark for the region.
- STEP 3. Local Support: Contact Sangamon Astronomical Society for updated site access and group observation schedules.
- STEP 4. Observation Density: There are 5 recognized sites near Chatham offering varied horizons and atmospheric stability levels.
Chatham 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 6 skies found at Log Cabins.
The Best Times for Stargazing in Chatham
While Winter offers the most consistent clear nights for Chatham, wait for the 4-day window surrounding the New Moon each month for the deepest contrast. Since the sun sets early in the late Winter months, you can often begin deep-sky imaging as early as 7 PM.
Expert Tips for Chatham Observers
When observing from Jim Edgar Panther Creek State Fish & Wildlife Area, try to position yourself facing away from the nearest major light dome. For Chatham residents, this usually means looking toward the rural horizons of IL 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 6 at Log Cabins (241.4 miles away) remains the benchmark for regional sky quality.

Log Cabins
Fort Donelson NB
Local Relevance
Chatham enthusiasts typically use the instrumented readings from Log Cabins to calibrate their deep-sky expectations for the area.
"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)."
Kemil Beach
Indiana Dunes NL
Local Relevance
Chatham enthusiasts typically use the instrumented readings from Kemil Beach to calibrate their deep-sky expectations for the area.
"The light dome of Michigan City (5 miles to the ENE) was very bright, but the dome from Chicago all the way to south of INDU is by far the greatest source of skyglow. The Milky Way was visible from 15° above the horizon at both ends. Not a lot of detail was visible in the Sagittarius or Cygnus star clouds. M31 was barely visible to the naked eye without using averted vision. Comparitively, for the region, this is not too bad a place to view the night sky. If not for the local glare sources, it would be fairly quick to dark adapt and be able to see many celestial features. Was able to see 6.2 LM in Ursa Major (which was over the lake to the darker north)."
