Asterisms charts the night sky in a beautifully detailed poster. Using a clever projection which maps both hemispheres onto a circle, it offers a combined view of the northern and southern skies.

Each element on the poster is placed by hand, taking great care to ensure there are no unsightly overlaps or awkward spaces. Stars show relative brightness by the size of their circle, and brighter stars are individually labelled. Major constellations and asterisms are shown, as well as other interesting galaxies, nebulae and the band of stars forming the Milky Way.

Asterisms uses the Isomer font family. SemiCondensed Bold is used to label constellations, Condensed Italic is used for other points of interest, and Mono SemiCondensed Medium for grid labels.
