Nights per month with at least 20 minutes of good viewing.

We count a night when the galactic centre is at least 10° above the horizon, the sky is fully dark (between astronomical dusk and dawn) and the Moon is below the horizon or less than 25% lit. City lights matter too: see the nearest dark area on the night sky page.
