Star Count

Upload a photo of the night sky. The site finds the bright dots, counts them as stars, and lists each one in a table. Click a row to see where that star sits in the picture. An AI check afterwards says whether the count looks roughly right. By Ryan Ormrod.

Sparse field of point stars on a dark sky — Sparse field — isolated point stars

Dense star field with a bright galactic band — Dense field — many magnitudes

Stars above a dark treeline silhouette — Horizon — stars above a treeline

Works best on dark skies with point-like stars (JPEG). Dense bands and horizons are included so you can compare counts.
