Carbon fibre or aluminium tube OTA
I've been given a 80mm achromatic objective lens and cell that I would like to put to some use. It's about 900mm FL making it about f12 or so. Probably be OK for a bit of planetary or something like that.

But the tube assembly is going to be a bit problematic.

Does anyone know where I can source a suitable tube? Or have any idea how to DIY a CF job.
