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 22:00 · OBSERVE 22:30–05:30 · 7H · MEAN 47

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

2200020406
CLOUD RETURNS 05:30
SET UP 22:00 · OBSERVE 22:30–06:30 · 8H · MEAN 58

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

2200020406
CLOUD RETURNS 06:30MOONLIGHT IGNORED FOR THIS TARGET
SET UP 23:00 · OBSERVE 23:30–05:30 · 6H · MEAN 44

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

HIGH CLOUD CLEARS 23:30CLOUD RETURNS 05:30
SET UP 03:00 · OBSERVE 03:30–05:30 · 2H · MEAN 39

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

2200020406
CLOUD RETURNS 05:30
SET UP 22:00 · OBSERVE 22:30–05:30 · 7H · MEAN 48

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