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 23:30 · OBSERVE 00:00–05:00 · 5H · MEAN 60

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

00020406
TWILIGHT BEGINS 05:00
SET UP 23:30 · OBSERVE 00:00–06:00 · 6H · MEAN 70

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

00020406
CLOUD RETURNS 06:00MOONLIGHT IGNORED FOR THIS TARGET
SET UP 23:30 · OBSERVE 00:00–05:00 · 5H · MEAN 55

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

00020406
TWILIGHT BEGINS 05:00
SET UP 23:30 · OBSERVE 00:00–05:00 · 5H · MEAN 45

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

00020406
TWILIGHT BEGINS 05:00
SET UP 23:30 · OBSERVE 00:00–05:00 · 5H · MEAN 62

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