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 00:30 · OBSERVE 01:00–03:00 · 2H · MEAN 39

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

CLOUD RETURNS 03:00
SET UP 00:30 · OBSERVE 01:00–06:00 · 5H · MEAN 50

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

010305
CLOUD RETURNS 06:00MOONLIGHT IGNORED FOR THIS TARGET
SET UP 00:30 · OBSERVE 01:00–03:00 · 2H · MEAN 36

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

010305
CLOUD RETURNS 03:00
SET UP 03:30 · OBSERVE 04:00–05:00 · 1H · MEAN 35

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

CLOUD BREAKS 04:00TWILIGHT BEGINS 05:00
SET UP 00:30 · OBSERVE 01:00–03:00 · 2H · MEAN 38

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