Ideas for a tube material for a solid tube OTA?
I've been thinking of turning my Heritage 130p into a 5" imaging Newtonian and right now I'm just adding up all the costs to see if it's cheaper to do so or just buy a 6" Newtonian locally. But basically, I was just asking what you would recommend for a solid tube? It seems like Sonotube or concrete forming tube is very common in the US, but it doesn't seem to be available in the sizes which I need, and appear to come in only very large sizes (>300mm, several metres long). Is PVC pipe a good option?
