A celestial map that plots stars on a sky projection (stereographic or azimuthal equidistant) with constellation stick-figure lines connecting notable stars. Star apparent magnitudes are represented by point size (brighter stars appear larger), and a coordinate grid overlays the chart for orientation. In the dark theme, a dark background mimics a night sky, making this an intuitive tool for identifying constellations and planning observations.
