Any idea what material is KRUPAX? Heard that these can be used to make optical tubes for telescopes.
Thanks.

can this be bought locally?
i'm rebuilding my dob and i don't feel up to another truss job. if i could get a large diameter tube it would make my life a lot simpler...
EDIT: apparently Markus Ludes (APM.de) makes his telescope tubes out of krupax. doesn't sound like something you can get on the cheap...
