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 22:30 · OBSERVE 23:00–01:00 · 2H · MEAN 52

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

SET UP 02:30 · OBSERVE 03:00–06:00 · 3H · MEAN 54

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

SET UP 22:30 · OBSERVE 23:00–01:00 · 2H · MEAN 46

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