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 00:30 · OBSERVE 01:00–05:00 · 4H · MEAN 46

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

SET UP 00:30 · OBSERVE 01:00–06:00 · 5H · MEAN 55

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

SET UP 02:30 · OBSERVE 03:00–05:00 · 2H · MEAN 47

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

SET UP 03:30 · OBSERVE 04:00–05:00 · 1H · MEAN 40

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