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 01:30 · OBSERVE 02:00–03:00 · 1H · MEAN 40

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

CLOUD BREAKS 02:00CLOUD RETURNS 03:00
SET UP 01:30 · OBSERVE 02:00–03:00 · 1H · MEAN 48

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

CLOUD BREAKS 02:00CLOUD RETURNS 03:00MOONLIGHT IGNORED FOR THIS TARGET
SET UP 01:30 · OBSERVE 02:00–03:00 · 1H · MEAN 35

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

CLOUD BREAKS 02:00CLOUD RETURNS 03:00
NO USABLE WINDOW FOR THIS TARGET TONIGHT

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

CLOUD NEVER DROPS BELOW 50%
SET UP 01:30 · OBSERVE 02:00–03:00 · 1H · MEAN 38

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