Master the night with Dark Night, the ultimate technical tool for planning and executing high-precision astrophotography.

Designed by and for photographers, Dark Night combines precise astronomical calculations, specialized meteorology, and powerful calculators in an interface optimized for real-world use in the field.

🌌 1. PRECISION PLANNING
Total Darkness Window: Locate periods of true darkness (astronomical twilight).

Galactic Center Visibility: Precise intervals for capturing the core of the Milky Way.

Complete Ephemeris: Accurate Sun and Moon data to prevent moonlight from affecting your deep-sky shots.

Interactive Timeline: Visualize the minute-by-minute transition from light to deep night.

☁️ 2. SPECIALIZED METEOROLOGY
3-Level Cloud Cover: Breakdown of cloud cover into low, medium, and high layers.

Field Alerts: Warnings for condensation (dew point), wind (shake), and visibility.

Success Indicator: Algorithms that evaluate whether conditions are suitable for capturing the Milky Way.

🧮 3. ADVANCED TECHNICAL CALCULATORS
NPF Rule: Stars as points based on pixel size and aperture (supersedes the outdated 500 Rule).

Star Trail Simulator: Calculates star trails, number of photos, and required memory card space (RAW).

Hyperfocal Distance: Maximizes depth of field in your nightscapes.

Diffraction Calculator: Find the "sweet spot" of your lens and avoid loss of detail.

EV Guide: Professional adjustment of ISO, aperture, and shutter speed.

🔭 4. FIELD TOOLS
Station Approach: Quickly align your star tracker with your phone's sensors.
