Solve and annotateany star image
Drop a photo of the night sky. SkySolver works out exactly where it points, then draws the grid, the constellations and 14,333 nebulae, clusters and galaxies onto it. Your photo never leaves the browser; only its stars do.
Knows where you pointed.
Without being told.
No coordinates, no field of view, no hints. SkySolver recognises the patterns of the stars in your photo and works out exactly which piece of sky it shows, lens distortion included.

Every object,
drawn to shape.
The solved photo becomes a map: the grid, the constellations and 14,333 nebulae, clusters and galaxies from the Messier, NGC, IC, Sharpless, Barnard and Lynds catalogues, with their real outlines, not just circles.
Orion, from Barnard's Loop to the Witch Head, annotated by the playground's own overlay code.
Make the sky yours.
Show only what matters for your photo, find any object in a click, and style every layer: colours, thickness and line styles for each object type or catalogue. The legend follows, and your choices are remembered.
