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 01:30 · OBSERVE 02:00–06:00 · 4H · MEAN 50

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

020406
TWILIGHT BEGINS 06:00
SET UP 01:30 · OBSERVE 02:00–07:00 · 5H · MEAN 56

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

020406
TWILIGHT BEGINS 07:00MOONLIGHT IGNORED FOR THIS TARGET
SET UP 01:30 · OBSERVE 02:00–06:00 · 4H · MEAN 46

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

020406
TWILIGHT BEGINS 06:00
SET UP 02:30 · OBSERVE 03:00–05:00 · 2H · MEAN 40

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

020406
CLOUD BREAKS 03:00
SET UP 01:30 · OBSERVE 02:00–06:00 · 4H · MEAN 50

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