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 21:00–04:00 · 7H · MEAN 51

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

2123010305
SET UP 20:30 · OBSERVE 21:00–00:00 · 3H · MEAN 62

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

2123010305
MOONLIGHT IGNORED FOR THIS TARGET
SET UP 20:30 · OBSERVE 21:00–00:00 · 3H · MEAN 65

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

2123010305
SET UP 20:30 · OBSERVE 21:00–23:00 · 2H · MEAN 70

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

2123010305
CLOUD RETURNS 23:00
SET UP 20:30 · OBSERVE 21:00–01:00 · 4H · MEAN 60

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