What are you doing tonight?

The same forecast, weighted for the target. Planetary work barely cares about moonlight; long exposures die on high cloud a visual observer would never notice.

SET UP 03:00 · OBSERVE 03:30–05:30 · 2H · MEAN 48

Darkness and moonlight dominate. Faint fuzzies need a genuinely dark sky more than they need steady air.

SET UP 21:00 · OBSERVE 21:30–06:30 · 9H · MEAN 43

Seeing is everything and moonlight is irrelevant. Bright targets punch through twilight, so darkness barely counts.

CLOUD RETURNS 06:30MOONLIGHT IGNORED FOR THIS TARGET
SET UP 03:00 · OBSERVE 03:30–04:30 · 1H · MEAN 49

Tolerates soft seeing, but high cloud wrecks a wide frame and moonlight raises the background everywhere.

HIGH CLOUD CLEARS 03:30CLOUD RETURNS 04:30
SET UP 03:00 · OBSERVE 03:30–04:30 · 1H · MEAN 38

Needs conditions to hold still for hours. Sustained transparency matters more than any single good hour.

Naked eye, whole sky. Total cloud and moonlight are the only things that count.
