These plans are for a how to build a rich-field telescope by yourself.
A rich-field telescope is an instrument that covers a fairly large segment of the sky and has good light-gathering ability.
For viewing nebulae, the Milky Way and the moon, it can't be surpassed. The best RFT (richest-field telescope) of the reflecting type is one having a 7-inch diameter mirror of f-4 value or about 59-inch focal length. A fairly long eyepiece of at least one inch or more in focal length should be used. In as much as Pyrex telescope blanks do not come in seven-inch diameters, the eight-inch diameter was selected for this project.
