More Great Information on Inch Parabolic:
Building a reflecting telescope?
I would like to build a telescope, I hope to build one with a 14 inch parabolic mirror as the primary mirror. I want to grind this mirror for two reasons:
1) I will enjoy the experience
2) I don't have £1,250 to spend on a mirror
So, I need to get hold of 14 inches of optical quality glass. I was thinking about using porthole glass, I've heard it needs to be 25mm thick is this correct. Also is there a site I could by one from or anywhere I could scavenge one from?
Larry is right, you will not be happy with your results. Porthole glass is no where near the quality of glass that you need for High Quality optical mirror.
Join a local Astronomical Society or astronomy club. They will have loaner scopes you can borrow until you save enough money to purchase a good scope on your own.
