As I understand it, in a retro-azimuthal projection straight lines joining any point to the designated centre is an isoazimuth to the designated centre.
See eg Hammer's https://en.wikipedia.org/wiki/Hammer_retroazimuthal_projection
Littro'shttps://en.wikipedia.org/wiki/Littrow_projection
Lots of books on map projections have details.
Kermit, I think you wanted these lines mapped back on to a sphere, or perhaps a different projection?
