Milky Way & night sky
From Tohono Chul, the Milky Way core is visible in a dark sky from February through October. June gives the longest window (about 6.3 hours on a moonless night), and the core peaks around 29° above the southern horizon. Our light-pollution model puts the sky at about Bortle 8 (city sky), so expect visible sky glow; drive away from towns for better results.
