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 21:00–07:00 · 10H · MEAN 65

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

ASTRONOMICAL DARK FROM 21:00TWILIGHT BEGINS 07:00
SET UP 19:30 · OBSERVE 20:00–07:00 · 11H · MEAN 62

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

TWILIGHT BEGINS 07:00MOONLIGHT IGNORED FOR THIS TARGET
SET UP 23:30 · OBSERVE 00:00–07:00 · 7H · MEAN 73

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

19212301030507
TWILIGHT BEGINS 07:00
SET UP 00:30 · OBSERVE 01:00–07:00 · 6H · MEAN 74

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

SET UP 23:30 · OBSERVE 00:00–07:00 · 7H · MEAN 74

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