How dark does it get, and what you’ll see
Darkness is the single biggest lever on what’s visible. From Porto’s Bortle 8 core you’ll catch the Moon, bright planets, and the brightest stars — but the Milky Way, meteor showers, and faint deep-sky objects need a darker site. Moving even two or three Bortle classes darker, which the nearest sites above offer, brings the Milky Way back and multiplies what a meteor shower delivers.
The other half is timing: a bright Moon washes out faint targets just like city light does. The best nights fall around the new Moon, or after the Moon sets, under clear skies. Stella folds the Moon, clouds, transparency, and seeing into one Tonight score for your exact location, so you know whether the drive is worth it before you leave.
