The Best Times for Stargazing in Coal City

Expert Tips for Coal City Observers
When observing from Peck Farm Park, try to position yourself facing away from the nearest major light dome. For Coal City 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 5 at Dune Trail (273.5 miles away) remains the benchmark for regional sky quality.

Peck Farm Park
" Heading out from Coal City toward this location will reward you with steady horizons. Meteor Watching Tip: Don't look at one spot; keep your eyes moving across the sky. Your peripheral vision is more sensitive to motion. "
Campton Township Parks and Recreation Open Space at Corron Farm
" Coal City observers often find this mid-distance site perfect for a full session. Vision Technique: Try 'Averted Vision'—look slightly to the side of a faint object to use the more light-sensitive rods in your eyes. "

Dune Trail
Sleeping Bear Dunes NL
Local Relevance
For observers in Coal City, Dune Trail serves as the definitive baseline for high-altitude transparency and localized skyglow data.
"Stars are soft, with a ring of moisture visible around bright stars. High airglow apparent. Milky Way just visible, no detials apparent. 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."
Kemil Beach
Indiana Dunes NL
Local Relevance
For observers in Coal City, Kemil Beach serves as the definitive baseline for high-altitude transparency and localized skyglow data.
"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)."
