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 01:00 · OBSERVE 01:30–05:30 · 4H · MEAN 44

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

2200020406
TWILIGHT BEGINS 05:30
SET UP 00:00 · OBSERVE 00:30–05:30 · 5H · MEAN 53

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 03:00 · OBSERVE 03:30–05:30 · 2H · MEAN 43

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

HIGH CLOUD CLEARS 03:30TWILIGHT BEGINS 05:30
SET UP 03:00 · OBSERVE 03:30–04:30 · 1H · MEAN 36

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

2200020406
HIGH CLOUD CLEARS 03:30
SET UP 02:00 · OBSERVE 02:30–05:30 · 3H · MEAN 46

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