Polyester resin coated black cardboard tube to suit a 10" newtonian.
Ideal for someone building a 10" dob.
Approx. 12.5" OD x 66" long (to suit up to an f/6).
The inside hasn't been blackened yet.
Never used and with no holes cut in it, I built this tube ~10 years ago as a replacement for my old dob. tube, but I changed to an aluminium tube instead.
It has a 0.5" wide plywood re-enforcing ring fitted into the front.
