Stargazing in Prairie du Chien is surprisingly rewarding if you know exactly where to set up your tripod. While enthusiasts often gather at Prairie Grove Park for its accessibility, scientific audits conducted by the National Park Service at Kemil Beach provide the most accurate reading of the regional sky quality, measuring at a Bortle 6.0. The transition between the urban infrastructure of Prairie du Chien and the more rural stretches of WI creates several ‘dark sky’ corridors.

The Best Times for Stargazing in Prairie du Chien

Since Prairie du Chien sits in a transitional light zone, viewing is best during the New Moon or after midnight when some commercial lighting is reduced.

Expert Tips for Prairie du Chien Observers

When visiting Prairie Grove Park, remember to check if the gates close at sunset or if a night-use permit is required. Binoculars are a favorite for regulars here for sweeping views of the Moon’s craters and larger constellations. Local enthusiasts often frequent this spot, making it a great place to meet experienced observers. Regardless of your gear, allow 30 minutes for your eyes to fully dark-adapt.

Kemil Beach

Indiana Dunes NL

19.88 SQM
Bortle Class 6

"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)."
