Tonight's limiting factor
Why thin high cloud ruins long exposures

Cirrus you can barely see will halo your bright stars, lift your background and vary between frames. Visual observers shrug it off. Long exposures integrate it, so it accumulates.

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 22:00 · OBSERVE 22:30–01:30 · 3H · MEAN 47

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

CLOUD RETURNS 01:30
SET UP 22:00 · OBSERVE 22:30–01:30 · 3H · MEAN 55

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

2200020406
CLOUD RETURNS 01:30MOONLIGHT IGNORED FOR THIS TARGET
SET UP 22:00 · OBSERVE 22:30–23:30 · 1H · MEAN 50

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

2200020406
CLOUD RETURNS 23:30
SET UP 22:00 · OBSERVE 22:30–23:30 · 1H · MEAN 39

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

2200020406
CLOUD RETURNS 23:30
SET UP 22:00 · OBSERVE 22:30–01:30 · 3H · MEAN 48

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