Cloud tracks show clear sky — a longer bar is better. The figure inside each track is the raw measurement.

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 20:30 · OBSERVE 21:00–22:00 · 1H · MEAN 36

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

19212301030507
HIGH CLOUD CLEARS 21:00
SET UP 20:30 · OBSERVE 21:00–23:00 · 2H · MEAN 42

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

NO USABLE WINDOW FOR THIS TARGET TONIGHT

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

NO USABLE WINDOW FOR THIS TARGET TONIGHT

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

SET UP 20:30 · OBSERVE 21:00–22:00 · 1H · MEAN 35

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