KIRKUS REVIEW

The great variety of telescopes from simple manual machines used by sailors on watch to more complicated mechanisms used by astronomers are described in detail and their principles of operation reduced to terms the interested youngster will understand. Important observatories are also covered with an eye toward pointing out major discoveries sighted there. From the passive to the active role, the young scientist is then invited to make his own telescope. Direct information unadorned by any special imagination.
