 That same year the DCNR commissioned a study on the wind farm's impact, which concluded the red warning lights on the wind turbines would not impact the darkness of the sky and would only be directly visible from the Astronomy Field under rare conditions.Others in the astronomy community challenged these conclusions and feared that new lights on "several dozen wind turbines near the park" will degrade observations and astrophotography.The study also recommended that the DCNR shield and redirect lights at the nearby Denton Hill State Park downhill ski area to make the sky even darker at Cherry Springs.
