Clarendon Hills
Stargazing Guide.
Discover why the Clarendon Hills area serves as a strategic corridor for IL observers. We combine community-vetted spots like Peck Farm Park with professional NPS sky reports at Dune Trail for a complete astronomical perspective.
Stargazing Logistics for Clarendon Hills
- STEP 1. Primary Staging Area: Peck Farm Park. This is your most reliable community-vetted hub within a ~19.0 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 Clarendon Hills offering varied horizons and atmospheric stability levels.
Clarendon Hills 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 Clarendon Hills
For the best experience, target the late-night window between 1 AM and 4 AM in Clarendon Hills. This is when local industrial lighting and residential 'sky glow' is at its minimum, and the most prominent Winter constellations are directly overhead at the zenith.
Expert Tips for Clarendon Hills Observers
Don't underestimate the power of peripheral vision (averted vision). At sites near Clarendon Hills, looking slightly to the side of a faint nebula will reveal much more detail than looking directly at it, especially when dealing with the Class 5+ suburban skies of the IL region. Scientific Context: While local conditions vary, the instrumented reading of Bortle 5 at Dune Trail (233.9 miles away) remains the benchmark for regional sky quality.

Dune Trail
Sleeping Bear Dunes NL
Local Relevance
The scientific findings at Dune Trail provide Clarendon Hills residents with the most reliable data on regional atmospheric stability.
"No clouds, but high moisture in atmosphere is creating poor transparency. Stars are soft, with a ring of moisture visible around bright stars. High airglow apparent. Milky Way just visible, no detials apparent."
Kemil Beach
Indiana Dunes NL
Local Relevance
Clarendon Hills enthusiasts typically use the instrumented readings from Kemil Beach to calibrate their deep-sky expectations for the area.
"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. 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)."
