Tonight's limiting factor
Conditions for planets and the Moon

Seeing is everything. Darkness and moonlight barely matter, and a hazy, humid night that ruins deep-sky work is often the steadiest night of the year for planetary detail.

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 19:30 · OBSERVE 20:00–06:00 · 10H · MEAN 62

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

HIGH CLOUD CLEARS 20:00TWILIGHT BEGINS 06:00
SET UP 19:30 · OBSERVE 20:00–07:00 · 11H · MEAN 74

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

HIGH CLOUD CLEARS 20:00TWILIGHT BEGINS 07:00MOONLIGHT IGNORED FOR THIS TARGET
SET UP 20:30 · OBSERVE 21:00–06:00 · 9H · MEAN 59

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

HIGH CLOUD CLEARS 21:00TWILIGHT BEGINS 06:00
SET UP 20:30 · OBSERVE 21:00–06:00 · 9H · MEAN 50

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

SET UP 19:30 · OBSERVE 20:00–06:00 · 10H · MEAN 66

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