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 00:00 · OBSERVE 00:30–02:30 · 2H · MEAN 40

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

CLOUD BREAKS 00:30CLOUD RETURNS 02:30
SET UP 00:00 · OBSERVE 00:30–04:30 · 4H · MEAN 49

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

CLOUD BREAKS 00:30CLOUD RETURNS 04:30MOONLIGHT IGNORED FOR THIS TARGET
SET UP 22:00 · OBSERVE 22:30–23:30 · 1H · MEAN 39

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

CLOUD RETURNS 23:30
NO USABLE WINDOW FOR THIS TARGET TONIGHT

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

CONDITIONS STAY BELOW THE USABLE THRESHOLD
SET UP 00:00 · OBSERVE 00:30–02:30 · 2H · MEAN 39

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