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 00:00–02:00 · 2H · MEAN 39

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

CLOUD RETURNS 02:00
SET UP 23:30 · OBSERVE 00:00–05:00 · 5H · MEAN 44

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

000204
TWILIGHT BEGINS 05:00MOONLIGHT IGNORED FOR THIS TARGET
NO USABLE WINDOW FOR THIS TARGET TONIGHT

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

000204
CLOUD NEVER DROPS BELOW 59%
NO USABLE WINDOW FOR THIS TARGET TONIGHT

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

000204
CLOUD NEVER DROPS BELOW 59%
SET UP 23:30 · OBSERVE 00:00–02:00 · 2H · MEAN 38

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