Forest Park
Stargazing Guide.
Just 25.2 miles from the center of Forest Park, lies some of the region's best viewing at Peck Farm Park. We feature instrumented readings from Dune Trail to guarantee the most accurate sky quality data.
Stargazing Logistics for Forest Park
- STEP 1. Primary Staging Area: Peck Farm Park. This is your most reliable community-vetted hub within a ~25.2 mile radius.
- STEP 2. Sky Quality Baseline: Classified as Class C (Suburban). Use the instrumented 5 rating from Dune Trail as your technical benchmark for the region.
- STEP 3. Local Support: Contact Chicago Astronomical Society for updated site access and group observation schedules.
- STEP 4. Observation Density: There are 5 recognized sites near Forest Park offering varied horizons and atmospheric stability levels.
Forest Park 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 5 skies found at Dune Trail.
The Best Times for Stargazing in Forest Park
Observation in Forest Park 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 Forest Park Observers
Thermal equilibrium is key. Since Forest Park temperatures can shift rapidly after sunset, allow your telescope mirrors at least 45 minutes to 'cool down' before attempting high-magnification work at Peck Farm Park. This prevents 'tube currents' from blurring your view of Jupiter or Saturn. Scientific Context: While local conditions vary, the instrumented reading of Bortle 5 at Dune Trail (226.5 miles away) remains the benchmark for regional sky quality.
Best Spots for Stargazing in Forest Park
The most accessible and reliable viewing locations in the region, ranked by local observer feedback. Pro Tip: Always bring a red-light flashlight to these Forest Park spots to preserve your night vision.
Peck Farm Park
" Forest Park observers often find this mid-distance site perfect for a full session. Sky Contrast Tip: To see the Milky Way, wait for the Moon to go below the horizon; even a 25% crescent Moon can wash out the faintest nebulae. "
Volo Bog
" Heading out from Forest Park toward this location will reward you with steady horizons. Light snacks and drinks will be available. Light snacks and drinks will be available. "
Modine-Benstead Observatory
" For the dedicated Forest Park observer, this spot offers a superior escape from light pollution. Atmospheric Tip: Scintillation (star twinkling) is a sign of high-altitude turbulence. If stars are twinkling heavily, stick to low-magnification wide views. "
Campton Township Parks and Recreation Open Space at Corron Farm
" Forest Park observers often find this mid-distance site perfect for a full session. Comfort Tip: The ground cools faster than the air. Bring a reclining chair to keep your neck strain-free during marathon observation sessions. "
Ela Area Public LIbrary
" A manageable drive from Forest Park, this spot is a reliable regional favorite. Light snacks and drinks will be available. "

Access high-precision SQM readings from the National Park Service, providing the definitive baseline for regional darkness quality. Seeing the faint magnitude targets listed in these NPS readings often requires the specific gear we've staged for Forest Park nights in our observer field kit.
Dune Trail
Sleeping Bear Dunes NL
Local Relevance
The scientific findings at Dune Trail provide Forest Park residents with the most reliable data on regional atmospheric stability.
"Travese City light dome dominates the eastern horizon. Reflection of Travese City dome is visible on Glen Lake, further impacting dark adaptation in that direction. Transparency improved over the night, with the best conditions at the end of data collection. Bortle Class would be better under better atmospheric conditions."
Kemil Beach
Indiana Dunes NL
Local Relevance
The scientific findings at Kemil Beach provide Forest Park residents with the most reliable data on regional atmospheric stability.
"Set up about 50' from the water in a depression in the sand dunes. Local glare from the western most home in the "1933 Century of Progress" homes. Other glare sources from the power plants to the SW and NE along the lakeshore are easily visible but did not saturate the camera sensor. A clear view across Lake Michigan to the Chicago skyline, though clouds and haze never completely cleared away. I suspect the industrial developments from the Port of Indiana all the way around to Chicago has a significant impact on aeresols and local cloud development. Even so, at 35 miles distant, the illuminated buildings of the Chicago skyline were easily visible to the naked eye on this evening. 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."
