This is a 3rd development of the travel scope idea.
The main design requirements are to make the scope compact and lightweight so that it is easy to transport. A normal Dobsonian Telescope of this aperture is phisically quite large - about 1500mm high with a tube diameter of 300mm. This scope will colapse down to a box 250mm x 250mm x 230mm plus some aluminium struts about 1200mm long.
Shown here is the kit of parts prior to assembly.
My next post will show the assembled telescope!
