Good tonight

Tonight's limiting factor
Civil, nautical and astronomical twilight

Astronomical darkness begins when the sun is 18° below the horizon. Above that, there is still measurable skyglow, and faint deep-sky work is compromised even though the sky looks black.

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 23:30 · OBSERVE 00:00–03:00 · 3H · MEAN 50

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

CLOUD RETURNS 03:00
SET UP 22:30 · OBSERVE 23:00–04:00 · 5H · MEAN 71

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

22000204
CLOUD RETURNS 04:00MOONLIGHT IGNORED FOR THIS TARGET
SET UP 23:30 · OBSERVE 00:00–03:00 · 3H · MEAN 49

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

22000204
CLOUD RETURNS 03:00
SET UP 23:30 · OBSERVE 00:00–03:00 · 3H · MEAN 41

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

22000204
CLOUD RETURNS 03:00
SET UP 23:30 · OBSERVE 00:00–03:00 · 3H · MEAN 54

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