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 21:30 · OBSERVE 22:00–05:00 · 7H · MEAN 47

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

212301030507
ASTRONOMICAL DARK FROM 22:00
SET UP 21:30 · OBSERVE 22:00–05:00 · 7H · MEAN 40

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

ASTRONOMICAL DARK FROM 22:00SEEING STAYS SOFT THROUGHOUTMOONLIGHT IGNORED FOR THIS TARGET
SET UP 21:30 · OBSERVE 22:00–05:00 · 7H · MEAN 46

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

212301030507
ASTRONOMICAL DARK FROM 22:00
SET UP 22:30 · OBSERVE 23:00–00:00 · 1H · MEAN 37

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

212301030507
SET UP 21:30 · OBSERVE 22:00–05:00 · 7H · MEAN 51

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