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 03:00–04:00 · 1H · MEAN 52

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

SET UP 02:30 · OBSERVE 03:00–04:00 · 1H · MEAN 47

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

HIGH CLOUD CLEARS 03:00CLOUD RETURNS 04:00MOONLIGHT IGNORED FOR THIS TARGET
SET UP 02:30 · OBSERVE 03:00–04:00 · 1H · MEAN 52

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

SET UP 02:30 · OBSERVE 03:00–04:00 · 1H · MEAN 39

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

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