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 22:30–01:30 · 3H · MEAN 40

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

2200020406
SET UP 22:00 · OBSERVE 22:30–03:30 · 5H · MEAN 38

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

2200020406
MOONLIGHT IGNORED FOR THIS TARGET
SET UP 22:00 · OBSERVE 22:30–23:30 · 1H · MEAN 37

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

2200020406
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 77%
SET UP 22:00 · OBSERVE 22:30–23:30 · 1H · MEAN 41

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