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 21:00–06:00 · 9H · MEAN 64

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

CLOUD BREAKS 21:00TWILIGHT BEGINS 06:00
SET UP 20:30 · OBSERVE 21:00–07:00 · 10H · MEAN 75

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

SET UP 20:30 · OBSERVE 21:00–06:00 · 9H · MEAN 59

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

SET UP 21:30 · OBSERVE 22:00–06:00 · 8H · MEAN 53

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

SET UP 20:30 · OBSERVE 21:00–06:00 · 9H · MEAN 68

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