Milky Way & night sky
From Foster Botanical Garden, the Milky Way core is visible in a dark sky from February through October. June gives the longest window (about 7.7 hours on a moonless night), and the core peaks around 40° above the southern horizon. Our light-pollution model puts the sky at about Bortle 9 (inner-city 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: 9 Bortle 9 — Inner-city sky. Only the Moon, planets and a few bright stars are visible. Modeled zenith brightness ≈ 17.77 mag/arcsec².
Weather & best season
Long-term NASA satellite data for this area show July as the clearest month (about 47% average cloud cover) and March as the cloudiest (61%). September is the warmest month and February the coldest, which matters for gear, snow access and how long batteries last at night.
