Pretty Deep Maps: a detailed all-sky astronomical atlas
Creators
Description
The Pretty Deep Maps astronomical atlas is a large hyperlinked collection of charts and indices in PDF format covering the entire sky, in the main to a magnitude of 18, with star-dense sections at a lower magnitude, and selected regions to a deeper magnitude. The atlas is intended as a convenient, portable, deep visual representation of all-sky astronomical datasets, and can be used for tasks such as identification of objects in photographs and observation planning. 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. The charts are accompanied by a set of sortable indices. The atlas can be used on any device with a PDF reader capable of supporting within- and cross-document links.
The dataset is described in a detailed technical document (guide.pdf).
