Our Stellar Universe. Stereoscopic Star Charts and Spectroscopic Key Maps by Thomas Edward Heath - 1905
In this atlas the author compiles the spectral types, magnitudes, and parallaxes of stars brighter than the 5th magnitude. The atlas begins with introductory text, then the properties of the stars are listed in the index, which is followed by 26 star charts. Then the stars are presented in 3D on 26 stereo cards designed to be viewed with the stereo viewers that were popular at that time.
