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.

Deep-sky visualPlanetary & lunarWide-field imagingLong exposureMeteor watching

SET UP 23:30 · OBSERVE 00:00–05:00 · 5H · MEAN 55

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

TWILIGHT BEGINS 05:00

SET UP 23:30 · OBSERVE 00:00–06:00 · 6H · MEAN 64

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

CLOUD RETURNS 06:00MOONLIGHT IGNORED FOR THIS TARGET

SET UP 23:30 · OBSERVE 00:00–05:00 · 5H · MEAN 51

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

TWILIGHT BEGINS 05:00

SET UP 23:30 · OBSERVE 00:00–04:00 · 4H · MEAN 42

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

00020406

SET UP 23:30 · OBSERVE 00:00–05:00 · 5H · MEAN 57

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