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 03:30 · OBSERVE 04:00–05:00 · 1H · MEAN 41

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

0305
TWILIGHT BEGINS 05:00
SET UP 02:30 · OBSERVE 03:00–06:00 · 3H · MEAN 46

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

0305
TWILIGHT BEGINS 06:00MOONLIGHT IGNORED FOR THIS TARGET
SET UP 03:30 · OBSERVE 04:00–05:00 · 1H · MEAN 38

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

0305
TWILIGHT BEGINS 05:00
NO USABLE WINDOW FOR THIS TARGET TONIGHT

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

0305
CONDITIONS STAY BELOW THE USABLE THRESHOLD
SET UP 03:30 · OBSERVE 04:00–05:00 · 1H · MEAN 41

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