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 20:30 · OBSERVE 21:00–00:00 · 3H · MEAN 41

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

1921230103
SET UP 19:30 · OBSERVE 20:00–00:00 · 4H · MEAN 54

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

1921230103
CLOUD BREAKS 20:00MOONLIGHT IGNORED FOR THIS TARGET
SET UP 20:30 · OBSERVE 21:00–23:00 · 2H · MEAN 40

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

1921230103
CLOUD RETURNS 23:00
NO USABLE WINDOW FOR THIS TARGET TONIGHT

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

1921230103
CONDITIONS STAY BELOW THE USABLE THRESHOLD
SET UP 20:30 · OBSERVE 21:00–00:00 · 3H · MEAN 41

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