On each plate: a stereographic chart centred on the constellation (north up, east left) with stars sized by magnitude down to mag 6.5, minimal stick figures, IAU boundaries and Messier objects; an all-sky Hammer projection locating it against the celestial equator and ecliptic; and a globe shading the band of Earth latitudes from which the entire figure clears the horizon at some point in the year. Area, rank, brightest star and culmination month round out the data block. Nothing is tied to a single observing site.
Sources: stars from the HYG database v4.1 (CC BY-SA), stick figures and IAU boundaries from d3-celestial (BSD-3). Areas, culmination months and visibility limits are computed from that geometry — the spherical-polygon areas agree with the published IAU values (Orion 594.1, Crux 68.5, Hydra 1302.5 deg²).
Installing: copy the .bmp files to the device over USB, open one in Browse Files, and choose set as sleep screen cover.
