Hi Guys/Gals,
I'm wanting to build a sun funnel for the transit of Venus and i was planning to follow the simple instructions found here
http://www.transitofvenus.org/june20...th-a-telescope
however i can't find the Da-Lite High Contrast Da-Tex (Rear) - Cut-to-Size Screen Material - 95774 in a store that ships to Australia.
Does anyone know where this screen material (or something of similar application) is available in Australia?
Many thanks
orfeo
