I'm looking to make a white-light solar scope, like this one here:

and need to find an f10 parabolic mirror.
Can anyone point me to a supplier in Australia?
It doesn't need the coatings, so even second hand ones with old mirror coatings would be fine as they would be being stripped off anyway.
Any help appreciated.
