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 43

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

020406
CLOUD RETURNS 03:00
SET UP 01:30 · OBSERVE 02:00–04:00 · 2H · MEAN 44

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

020406
MOONLIGHT IGNORED FOR THIS TARGET
SET UP 01:30 · OBSERVE 02:00–03:00 · 1H · MEAN 36

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

020406
CLOUD RETURNS 03:00
NO USABLE WINDOW FOR THIS TARGET TONIGHT

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

020406
CLOUD NEVER DROPS BELOW 56%
SET UP 01:30 · OBSERVE 02:00–03:00 · 1H · MEAN 40

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