[umamqtaa] Celestial and global spheres

Play around with overlaying the celestial sphere onto the surface of the earth. 1 meter on earth = 32 milliarcseconds in the sky, which is finer than the resolving power of the Hubble Space Telescope.  Depict asterisms "actual size": it'll usually take huge amounts of area.

Inspired by the hoax of an ancient civilization aligning their cities with the stars.

Previously similar.  Also xkcd 1276 "Angular size".
