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 21:00 · OBSERVE 21:30–00:30 · 3H · MEAN 52

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

2123010305
CLOUD RETURNS 00:30
SET UP 21:00 · OBSERVE 21:30–02:30 · 5H · MEAN 54

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

2123010305
MOONLIGHT IGNORED FOR THIS TARGET
SET UP 21:00 · OBSERVE 21:30–22:30 · 1H · MEAN 61

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

2123010305
CLOUD RETURNS 22:30
SET UP 21:00 · OBSERVE 21:30–22:30 · 1H · MEAN 52

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

2123010305
CLOUD RETURNS 22:30
SET UP 21:00 · OBSERVE 21:30–00:30 · 3H · MEAN 52

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