3-D atlas of stars and galaxies

This atlas offers very much more than unique and three-dimensional views of the universe. Here are three comprehensive full-sky map sequence including 3-D stereographs. They cover local space (out to about 25 parsecs), regional space (showing the naked-eye stars to magnitude 6.5) and distant space (large-scale groupings of over 20,000 galaxies). The stereographs can be used to directly measure the approximate distance of any of the objects they show. All the 3-D maps have been derived from the most accurate distance data available, including the astonishing results produced by the Hipparcos satellite, which made between 100 and 150 separate observations of more than 100,000 stars to determine their parallax. The distant space maps represent probably the most complete mappings of the galaxies available to amateur astronomers, and their accompanying three-dimensional views provide tantalising glimpses of structure at the largest scale of the universe.
