Solved field · live celestial overlayThe process
From phone photo to explorable sky.
NightTrace solves the photograph once into astronomical geometry, then the browser keeps that map live and interactive.
Match the star pattern
Astrometry identifies where the camera was pointing. Capture time, location, and field width can narrow the search.
Watch the reveal
Real solver stages lead into a cinematic overlay of constellation context, bright stars, deep-sky objects, coordinates, and distance.

Personal observing history
Every capture becomes a chapter.
First discoveries, return visits, equipment, distance records, and quality changes remain connected to the photograph that created them.
