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 21:00 · OBSERVE 21:30–03:30 · 6H · MEAN 53

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

2123010305
SET UP 21:00 · OBSERVE 21:30–05:30 · 8H · MEAN 59

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

2123010305
TWILIGHT BEGINS 05:30MOONLIGHT IGNORED FOR THIS TARGET
SET UP 21:00 · OBSERVE 21:30–02:30 · 5H · MEAN 50

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

2123010305
SET UP 23:00 · OBSERVE 23:30–01:30 · 2H · MEAN 45

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

2123010305
HIGH CLOUD CLEARS 23:30
SET UP 21:00 · OBSERVE 21:30–03:30 · 6H · MEAN 53

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