Methodology

How decisions are produced

The Star Window converts nightly conditions into a decision-first forecast so users can quickly choose whether to go, where to go, and when to go.

Core factors

  • Cloud cover across likely observation windows
  • Moon interference for contrast-sensitive viewing
  • Darkness potential and local light pollution
  • Regional timing stability and limiting factors
