Duana Beckwith:
Anyone make a minimalist dob with alloy or CF and strings in 10" or larger size?
I recall one by Litescopes a few decades back which fit in a bag.

I'm planning to make my 20" a string telescope. So far I'm still finishing my 8" (mirror is at OWL for coating). Did you look at Don Peckham's page:http://dbpeckham.com...StringScope.htm I have a build thread for my 8" called Charlie's first scope.

I have one in the works - a 16" f/4 - it will be a tensegrity style based on the one created by Don Peckham. I have been meaning to start a build thread for quite a while - just haven't gotten to it yet. I have a picture attached of my OTA structure - currently using 1/16" steel cable as a mock-up - the strings themselves will be either BCY450 or UltraCAM bowstring material (I managed to find UltraCAM online - it has been discontinued by the manufacturer).
Several folks here in Portland have built string telescopes - Dan Gray is the original creator; David Nemo built a 20" string telescope and had a build thread here.

I've got your tensegrity right here...

Is that a bicycle wheel for the UTA?
