In Czech we have interesting construction for dobsons. It looks like box but it is very stable. Folded dobson can by transported by one man and assembled in two minutes. No colimination is needed. On pictures is 400/1670 mm dobson, it have 30 kg.

Janek,

Welcome to the boards.

That is indee, a very interesting design. I am wondering what mechanism is used to stop each segment flexing with respect to each other?

It is made from airplane plymouth with high precision. So four screws (? worms) for each segmet are enought. Scope is coliminated even if you move it in vertical direction. This wood is very good, but also very expensive.
