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 21:30 · OBSERVE 22:00–03:00 · 5H · MEAN 50

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

HIGH CLOUD CLEARS 22:00CLOUD RETURNS 03:00
SET UP 21:30 · OBSERVE 22:00–05:00 · 7H · MEAN 57

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

HIGH CLOUD CLEARS 22:00CLOUD RETURNS 05:00MOONLIGHT IGNORED FOR THIS TARGET
SET UP 21:30 · OBSERVE 22:00–03:00 · 5H · MEAN 43

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

SET UP 21:30 · OBSERVE 22:00–00:00 · 2H · MEAN 39

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.
