Rough grinding. This step is about making one side of the glass concave. It will give your mirror its overall focal ratio. If you make the centre deep, you will end up with a fast telescope (e.g. F/D = 4) well suited for deep sky observations. On the opposite, a shallow mirror (e.g. F/D = 8) will be performing very well on planets and the moon.

Maybe larger. John was no youngster in this video and even though he is a master, he sure put a hellova lot of labor into that mirror.

Typically, the primary mirror is made of glass. Pyrex is commonly used for the primary mirror because of its thermal stability, but for small mirrors, plate glass will work fine too. Telescope mirrors are relatively thick. The concave shaped face is made by repeatedly rub the primary glass blank over another blank called the “tool”.
