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 02:30 · OBSERVE 03:00–06:00 · 3H · MEAN 57

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

HIGH CLOUD CLEARS 03:00TWILIGHT BEGINS 06:00
SET UP 22:30 · OBSERVE 23:00–06:00 · 7H · MEAN 56

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

SET UP 02:30 · OBSERVE 03:00–06:00 · 3H · MEAN 52

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

SET UP 03:30 · OBSERVE 04:00–06:00 · 2H · MEAN 49

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

SET UP 02:30 · OBSERVE 03:00–06:00 · 3H · MEAN 57

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