◌ Satellite Trail Risk — Astrophotography Coming Soon

Automated trail-risk prediction for your imaging session is planned. Configure your target below; the prediction engine will flag pass windows crossing your FOV.

Session Parameters (not yet active)

Target RA / Dec FOV (arcmin)

Session start Duration (minutes) Exposure length (sec)

ISS Mag −2 to −4 at best passes. Very bright streak. Skip the frame.

Starlink trains Mag 3–5 within days of launch. Use Tonight's Passes panel above for timing.

Stacking mitigation Sigma-clipping / Winsorized rejection removes single-frame satellite trails automatically.

Orbital Interference The Orbital Interference tool shows a real-time sky view of objects above your horizon.
