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 23:30 · OBSERVE 00:00–04:00 · 4H · MEAN 53

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

SET UP 19:30 · OBSERVE 20:00–05:00 · 9H · MEAN 56

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

SET UP 23:30 · OBSERVE 00:00–04:00 · 4H · MEAN 49

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

SET UP 23:30 · OBSERVE 00:00–03:00 · 3H · MEAN 41

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