All-sky gnomonic projection of the celestial sphere. Star size & brightness scale with magnitude; deep-sky objects are coloured by class; the Milky Way is a real band along the J2000 galactic plane. Data: the cited KullGames Cosmos catalogue (public-domain / CC0 sources). Self-contained — no build, no dependencies.
