The Best Times for Stargazing in Peoria
While Winter offers the most consistent clear nights for Peoria, 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 Peoria Observers
When observing from Ben Butterworth Center, try to position yourself facing away from the nearest major light dome. For Peoria 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 (309.2 miles away) remains the benchmark for regional sky quality.

Ben Butterworth Center
" For the dedicated Peoria observer, this spot offers a superior escape from light pollution. 'Al presented on the occultation of Mars by the Moon and then we went outside and observed this event through his 10 telescope.' "
Niabi Zoo
" For the dedicated Peoria observer, this spot offers a superior escape from light pollution. Comfort Tip: The ground cools faster than the air. Bring a reclining chair to keep your neck strain-free during marathon observation sessions. "
Jim Edgar Panther Creek State Fish & Wildlife Area
" While it's a bit of a journey from Peoria, the sky quality here is worth the fuel. Scientific Fact: Around 3 AM, the atmosphere is usually most stable, offering the 'steadiest seeing' for high-magnification planetary views. "
Illiniweek Campground
" While it's a bit of a journey from Peoria, the sky quality here is worth the fuel. Thermal Mastery: Set your telescope out an hour early to allow the mirrors to reach 'thermal equilibrium' with the night air. "
Butterworth Center and Deere-Wiman House

Log Cabins
Fort Donelson NB
Local Relevance
The scientific findings at Log Cabins provide Peoria residents with the most reliable data on regional atmospheric stability.
"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
The scientific findings at Kemil Beach provide Peoria 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. 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)."
