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.

NO USABLE WINDOW FOR THIS TARGET TONIGHT

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

NO USABLE WINDOW FOR THIS TARGET TONIGHT

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

NO USABLE WINDOW FOR THIS TARGET TONIGHT

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

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

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