A general guide to astronomy; some say it should be called the Astronomical Treasury. Same large page-size as the Astronomical Calendar. Begins with an “Overview of Astronomy”and pictures that almost force you to understand coordinate systems and orientation in space.
A strand running through the book is the series of 30 ten-inch-diameter diagrams showing expanding spheres of space, from the Moon's orbit and the domains of planets and comets out through the nearest stars, the brightest stars, the neighboring regions of our Milky Way galaxy, the whole galaxy, the Local Group of galaxies, the Virgo Supercluster, the domain of the quasars, and on to the eerie limit of the universe.
