Is tonight worthy?
One score that tells you whether to haul the telescope out. Nightworthy weighs the clouds, the moon, true darkness, seeing and dew for every location you save — the way your kind of astrophotography needs it weighed.

A score, not a spreadsheet
Every saved spot gets a 0–100 verdict for tonight. Tap it when you want the hourly detail — skip it when you don't.
Your best window
Full moon rising at midnight? Clouds clearing at 2 AM? Nightworthy finds the best stretch of usable sky inside tonight's darkness, per location.
It knows the difference
An 84% moon ruins nebulae but Jupiter couldn't care less. The same night scores differently per mode — because your targets do too.
