Hi ppl , a couple of months ago I got a 4" newt for a present and it's a cheap and nasty from china , but it's got me hooked on star gazing and now I want a bigger apperture (8") . I bought this book called "Build your own telescope" by Richard Berry and now I want to have a go at building one myself, but I dont know where to source the glass blanks or the abrassives to make a mirror.I know people will try and tell me it's probably not worh making it but I get great satisfaction from making my own telescope from the ground up.I live in the Sydney , Homebush area can anyone point me in the right direction and maybe give us an approx price for the 2 glass blanks ....thanks .
