Tonight's limiting factor
What the GoodSeeing score actually measures

One number from 0 to 100 per hour, combining cloud, transparency, seeing, moonlight and darkness. Cloud gates everything else — no amount of steady, dark air rescues an overcast sky.

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 22:30 · OBSERVE 23:00–04:00 · 5H · MEAN 53

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

TWILIGHT BEGINS 04:00
SET UP 22:30 · OBSERVE 23:00–04:00 · 5H · MEAN 51

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

230103
TWILIGHT BEGINS 04:00MOONLIGHT IGNORED FOR THIS TARGET
SET UP 22:30 · OBSERVE 23:00–04:00 · 5H · MEAN 54

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

TWILIGHT BEGINS 04:00
SET UP 00:30 · OBSERVE 01:00–04:00 · 3H · MEAN 53

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

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