David Aitoff (1854-1933)

a Russian cartographer, who proposed the modified azimuthal map projection that bears his name: the Aitoff Projection

This projection is the one we use in our cosmographic maps, as illustrated in the following thread ⤵️

Side-by-side: All-sky Aitoff projections of the positions of galaxies from the XSCz Catalog: 1) all galaxies, 2) only galaxies located within the boundaries of Laniakea, our home supercluster of galaxies.
An Aitoff projection of the South Pole Wall in celestial coordinates. The projection is centered on the south pole, an operation which duplicate the north pole.
