About this app

AstroLens is your personal gateway to the cosmos. Simply point your device at the sky to identify stars, constellations, planets, and satellites in real-time using cutting-edge Augmented Reality (AR).

Whether you are a casual stargazer or a seasoned astrophotographer, AstroLens provides academic-grade precision tools to explore, capture, and understand the night sky.

🚀 KEY FEATURES

Real-Time AR Sky Map: Hold your phone up to see a live map of the stars and constellations. Premium sensor fusion ensures pinpoint accuracy, while one-touch star calibration lets you correct local magnetic interference instantly.
Professional Astrophotography Stacking: Capture stunning night-sky images directly on your mobile device. Our professional-grade engine uses 32-bit floating-point accumulation, sub-pixel star centroiding, Welford's 3-sigma outlier rejection (to eliminate satellite passes and airplane trails), and pixel-level dark/flat frame noise calibration.
High-Precision Orbital Tracking: Track the ISS and bright LEO satellites with real-time SGP4 orbital propagation, look-vector projections, and warnings for stale orbital elements.
Interactive 3D Solar System Orrery: Decouple from the present moment to scrub through orbital alignments and planetary orbits across a ±5-year timeline. Play, pause, and adjust simulation speeds to watch Mars retrograde and Keplerian physics in action.
On-Device AI Science Badge: Explore spectroscopic details for iconic stars. View OBAFGKM spectral classification badges, Doppler radial velocity vectors (redshift/blueshift), and animated light curves for variable stars (like Algol and Betelgeuse) on an inverted astronomical scale.
Atmospheric Refraction Warping: Rest assured that virtual coordinates align perfectly with physical optics. Our engine dynamically warps the Milky Way, coordinate grids, and the ecliptic line near the horizon based on live temperature and pressure readings.

🌌 DESIGNED FOR PRIVACY
AstroLens is built with a privacy-first architecture. Your location is processed strictly on-device for celestial coordinates. To fetch real-time atmospheric conditions (temperature, pressure), coordinates are securely resolved via a third-party weather service (Open-Meteo). Camera data and AI calculations run entirely offline on your device. No personal data is ever stored or sold.

🛠 ADVANCED OBSERVATION TOOLS
Bortle Scale Simulator: Calibrate star density based on your local light pollution, or toggle Sensor Aperture Mode to bypass culling and simulate deep-exposure camera sensitivity.
Tactile Gaze Haptics: "Feel" the brightness of the cosmos with graded magnitude-based haptics (distinct ticks for planets, micro-pulses for deep-sky nebulae).
Night Mode: Protect your eyes in dark-sky locations with a premium, eye-friendly red interface.

Discover the beauty of the universe with AstroLens. Clear skies!
