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 22:00 · OBSERVE 22:30–23:30 · 1H · MEAN 44

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

CLOUD RETURNS 23:30
SET UP 22:00 · OBSERVE 22:30–23:30 · 1H · MEAN 41

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

2200020406
CLOUD RETURNS 23:30MOONLIGHT IGNORED FOR THIS TARGET
SET UP 22:00 · OBSERVE 22:30–23:30 · 1H · MEAN 39

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

2200020406
CLOUD RETURNS 23:30
NO USABLE WINDOW FOR THIS TARGET TONIGHT

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

2200020406
CLOUD NEVER DROPS BELOW 63%
SET UP 22:00 · OBSERVE 22:30–23:30 · 1H · MEAN 43

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