    "The process is described in great detail so that the making of the mirror is an enjoyable and relaxing task. Simple test methods are described so that you do not over grind the mirror but achieve the correct shape. How to simply mount the mirror in a tube is then covered in detail. The result will be a working astronomical telescope capable of viewing the Heavens. Only everyday tools are required throughout"--P. [4 of cover].
