Many years ago I used a 6" PVC tube for a 4.5" Newtonian telescope. It worked OK. I have noticed that PVC has more water condense on it than wood does. My current Newtonian telescope has an 8" mirror and the tube is made out of 1/4" plywood. My "tube" is square with 1" plywood used on both ends to strengthen the tube. I also used 1" x 2" wood strips running the length of the tube for strength. This telescope works very well, was easy to make, and is easy to use. I recommend this design highly.
