Pretty Deep Maps

Martin has found a new home for his "Pretty Deep Maps"

These cover the whole sky down to mag 18.
The charts plot approximately 117k bright stars, 600 million field stars, 2.4 million galaxies, 277k variable stars, 110k multiple stars, 168k quasars, 8955 galaxy groups, 5250 galaxy clusters, 5004 dark nebulae, 2411 planetary nebulae, 1249 bright nebulae, 2167 open clusters, 159 reflection nebulae and 157 globular clusters. The celestial sphere is divided into 6787 charts, each covering 3 degrees of declination at a map scale of 11.74" per mm. Charts employ a gnomonic projection.
