This short work is written primarily for the benefit of those interested in astronomy who wish to possess an instrument capable of extending their exploration of the universe without involving a large capital outlay.
A secondary object is to introduce to those seeking a hobby demanding patience and extreme accuracy, the fascinating art of telescope-mirror making. By accuracy I do not mean the " tenth thou." of the mechanical engineer; for a mirror to be of service it must be worked to an accuracy of something like ten millionths of an inch. Impossible for an amateur? Not a bit. I have made several mirrors ranging from 6 in. to 12 in. in diameter, and being an accountant by profession I cannot lay claim to possessing any special mechanical skill.
If you are interested, digest the following pages and then go to it. The production of your first mirror will be its own reward.
