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 21:00–01:00 · 4H · MEAN 51

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

ASTRONOMICAL DARK FROM 21:00CLOUD RETURNS 01:00
SET UP 19:30 · OBSERVE 20:00–01:00 · 5H · MEAN 58

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

HIGH CLOUD CLEARS 20:00CLOUD RETURNS 01:00MOONLIGHT IGNORED FOR THIS TARGET
SET UP 20:30 · OBSERVE 21:00–01:00 · 4H · MEAN 47

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

ASTRONOMICAL DARK FROM 21:00CLOUD RETURNS 01:00
SET UP 20:30 · OBSERVE 21:00–00:00 · 3H · MEAN 39

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

ASTRONOMICAL DARK FROM 21:00CLOUD RETURNS 00:00
SET UP 20:30 · OBSERVE 21:00–01:00 · 4H · MEAN 53

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