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 01:30 · OBSERVE 02:00–03:00 · 1H · MEAN 38

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

SET UP 01:30 · OBSERVE 02:00–05:00 · 3H · MEAN 54

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

SET UP 01:30 · OBSERVE 02:00–03:00 · 1H · MEAN 41

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

NO USABLE WINDOW FOR THIS TARGET TONIGHT

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

NO ASTRONOMICAL DARKNESS
SET UP 01:30 · OBSERVE 02:00–03:00 · 1H · MEAN 41

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