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 18:30 · OBSERVE 19:00–01:00 · 6H · MEAN 64

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

CLOUD RETURNS 01:00
SET UP 18:30 · OBSERVE 19:00–01:00 · 6H · MEAN 73

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

CLOUD RETURNS 01:00MOONLIGHT IGNORED FOR THIS TARGET
SET UP 18:30 · OBSERVE 19:00–01:00 · 6H · MEAN 62

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

19212301030507
CLOUD RETURNS 01:00
SET UP 18:30 · OBSERVE 19:00–01:00 · 6H · MEAN 52

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

CLOUD RETURNS 01:00
SET UP 18:30 · OBSERVE 19:00–01:00 · 6H · MEAN 69

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