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 20:30 · OBSERVE 21:00–02:00 · 5H · MEAN 55

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

CLOUD BREAKS 21:00
SET UP 20:30 · OBSERVE 21:00–03:00 · 6H · MEAN 65

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

CLOUD BREAKS 21:00CLOUD RETURNS 03:00MOONLIGHT IGNORED FOR THIS TARGET
SET UP 20:30 · OBSERVE 21:00–02:00 · 5H · MEAN 49

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

CLOUD BREAKS 21:00
SET UP 20:30 · OBSERVE 21:00–01:00 · 4H · MEAN 40

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

CLOUD BREAKS 21:00
SET UP 20:30 · OBSERVE 21:00–02:00 · 5H · MEAN 57

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