One J2000 catalogue solution. The radiant drifts during the season; this illustration does not model that drift.

A constellation is an area of sky, not one coordinate.
About this sky & sources +
Catalogue stars and traditional line patterns share one celestial projection. Terrain and mythological figures are original artistic interpretations.
Art preserves the composed scene. Horizon uses the labelled reference location and time and true cardinal directions, with a level mathematical horizon. Its continuous illustrated panorama is an imagined setting, not surveyed terrain.
Catalogue coordinates use J2000 and are precessed to the scene date. Weather, moonlight, terrain obstruction and atmospheric refraction are not modelled. This is a learning view, not an observing forecast.
