I have just finished this light, collapsible telescope. It weighs 9.5kg (mirror included). The strut is fibeglass as is the spider/light shield. It has a gooseneck, which means that you do not view from the side but from 45 degrees. This overcomes the problems of the Litescope at low angles. The triangles and the trunnion are made out laminated, hard merante, veneers. The azimuth bearings are 2X ball races and one teflon bearing. I found that three teflon bearings tended to stick a bit when conditions are dewy.
