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 23:00 · OBSERVE 23:30–05:30 · 6H · MEAN 45

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

HIGH CLOUD CLEARS 23:30TWILIGHT BEGINS 05:30
SET UP 22:00 · OBSERVE 22:30–05:30 · 7H · MEAN 48

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

TWILIGHT BEGINS 05:30MOONLIGHT IGNORED FOR THIS TARGET
SET UP 00:00 · OBSERVE 00:30–05:30 · 5H · MEAN 40

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

2123010305
TWILIGHT BEGINS 05:30
SET UP 02:00 · OBSERVE 02:30–03:30 · 1H · MEAN 36

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

CLOUD RETURNS 03:30
SET UP 23:00 · OBSERVE 23:30–05:30 · 6H · MEAN 45

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