Drat! Pipped to the post - I've been working on something very similar (on and off) for a while, including the split alt-bearings and six-tube truss joined top and bottom. Still, he has come up with a few nice ideas there and put them together into a great looking scope!

Yea, I've been following this one on the obsession user group for a while now, a nice scope, has many advantages to the brute force traditional dobs in terms of weight, one draw back is no mirror protection.

Having said that, this scope does look like you would get it into a bag on a plane, so this could be a scope you could bring on holidays.

What struck me as a little odd was the aperture. I would have thought that an ultra-light dob would open the doors to even greater aperture.
