What it checks

If the galactic core never rises during darkness, Sky Sync says so plainly.

A short moon-free window caps the score, however clear the sky.

The same half moon ruins a truly dark site and barely matters near a city. Sky Sync models moonlight against the measured darkness of your spot.

Sky darkness comes from satellite measurements of light, not a static map.

Sky Sync shows which direction the nearest city glow sits, so you know before you frame.
