Tonight's limiting factor
When a clear gap is worth driving for

Ask how long the gap is relative to your setup time and your exposure length. A two-hour gap is a real session for a visual observer and close to worthless for someone doing four-minute subs on a target that needs three hours.

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 03:00–05:00 · 2H · MEAN 45

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

CLOUD BREAKS 03:00
SET UP 02:30 · OBSERVE 03:00–05:00 · 2H · MEAN 56

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

CLOUD BREAKS 03:00MOONLIGHT IGNORED FOR THIS TARGET
SET UP 02:30 · OBSERVE 03:00–05:00 · 2H · MEAN 42

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

CLOUD BREAKS 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.

CONDITIONS STAY BELOW THE USABLE THRESHOLD
SET UP 02:30 · OBSERVE 03:00–05:00 · 2H · MEAN 44

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