Milky Way & night sky
From University of Kentucky Research and Education Center Botanical Garden, the Milky Way core is visible in a dark sky from March through October. June gives the longest window (about 5.5 hours on a moonless night), and the core peaks around 24° above the southern horizon. Our light-pollution model puts the sky at about Bortle 5 (suburban sky), so expect visible sky glow; drive away from towns for better results.

Window when the galactic core is at least 10° high during astronomical darkness on the 15th of each month. Pick nights within a few days of the new moon. Plan exact nights with the Milky Way planner.
Estimated sky darkness: 5 Bortle 5 — Suburban sky. The Milky Way is weak near the horizon and washed out overhead; long exposures pick up a sky glow. Modeled zenith brightness ≈ 20.24 mag/arcsec².
Weather & best season
Long-term NASA satellite data for this area show September as the clearest month (about 45% average cloud cover) and February as the cloudiest (69%). July is the warmest month and January the coldest, which matters for gear, snow access and how long batteries last at night.
