AR sky overlay
The camera feed is the background; sky objects project onto it from your device's orientation. When a target is off-screen, an arrow points the way.
What it does
Sun & Moon
Rise/set times, and for the Moon: phase, illuminated fraction, distance, and a cloud-aware visibility score.
Planets
Mercury through Neptune, with magnitude and position from an orbital model.
Stars & constellations
~8,900 stars to magnitude 6.5 from the HYG database, plus all 88 IAU constellations with line figures, names and mythology.
Deep-sky objects
The 110 Messier objects with type, magnitude, size and per-object notes; headliners ship with a bundled photo.
Planetary moons
14 major satellites of Mars, Jupiter, Saturn, Uranus and Neptune.
Search everything
Prefix search across bodies, named and Bayer stars, constellations, satellites and Messier objects.
Reference overlays
Ecliptic, celestial equator, meridian, horizon and a coordinate grid — all toggled from a layers panel.
Time travel
A slider scrubs ±3 days to preview the sky at any moment.
Night mode
A red filter that preserves your dark adaptation.
Cloud cover
Current and hourly cloud cover from the free Open-Meteo API (no key), folded into the visibility score.
True-north correction
Applies local magnetic declination so the overlay aligns with the real sky.

Privacy by default
No accounts, no ads, no analytics, no servers operated by us. Camera frames are processed on-device and never recorded or transmitted. The only thing ever sent off your device is your approximate location to Open-Meteo, solely to fetch local cloud cover.
