The Best Times for Stargazing in Long Grove
Observation in Long Grove 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 Long Grove Observers
If you're visiting Volo Bog, bring a pack of chemical hand-warmers and rubber-band them to your eyepiece or camera lens. This acts as a 'budget' dew heater, which is essential for the humid nights often found in IL during the peak viewing seasons. Scientific Context: While local conditions vary, the instrumented reading of Bortle 5 at Dune Trail (210.0 miles away) remains the benchmark for regional sky quality.

Local Relevance
The scientific findings at Dune Trail provide Long Grove 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

Local Relevance
Long Grove enthusiasts typically use the instrumented readings from Kemil Beach to calibrate their deep-sky expectations for the area.
"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."
