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 02:30 · OBSERVE 03:00–05:00 · 2H · MEAN 59

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

SET UP 01:30 · OBSERVE 02:00–05:00 · 3H · MEAN 58

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

SET UP 02:30 · OBSERVE 03:00–05:00 · 2H · MEAN 53

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

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

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