I'm not sure if it will necessarily be cheap, maybe cheaper than an off the shelf mirror of equivalent size. This is what John Dobson (of the Dobsonian) is famous for. However you still need to do stuff like coat the primary mirror once it's polished and you can't easily do that at home.

- chantepierre 4y agoSilvering mirrors is coming back in fashion, either with the old recipe à la Jean Texereau / How to make a telescope, or with a spray silvering process. This week I silvered my last mirror with spray silvering, which was quite economical and convenient. I used 1.6g of silver nitrate for a 200mm mirror.
