Celestial Wonders: Meteors Dance Over the Swiss Alps

    "composition": "ultra-wide, eye-level from a high-altitude frozen lake at 2,000 m, pristine snow foreground, 360° unobstructed sky",
    "camera_motion": "0–2 s: locked-off; 2–10 s: ultra-slow 0.02 m/s forward dolly-in with 1° upward micro-tilt to keep the radiant near Boötes centered; no lateral drift",

    "lens": "14 mm rectilinear ultra-wide, f/1.8",
    "stabilization": "tripod slider with electronic gyro lock, no micro-jitters",
    "film_grain": "none—clean astro-grade clarity"

  "scene": {
    "environment": "crystal-clear winter night in the Swiss Alps, −12 °C, zero light pollution",

  "visual_details": {
    "meteors": {
      "appearance": "intense white-blue streaks up to mag −3, occasional green ionization tails, rare persistent trains",
