THE PROTOTYPE 
I bet a Dobson RC had not yet seen ( Fortunately 
), good! Also this gap was filled, Grattavetro now and we do not miss anything ! 
As already mentioned, I recycled much of my old Dobson, enough to build the prototype with plywood instead of aluminum, intubation test the project and test the mirrors while comfortably ( not so, no need for a hike in the base ) sitting. When the work will be expected to better construction, especially for the frame.
Do not mind the background, It is not a war zone, we are simply renovating… 
Now I want to go on to post Dobsonians , I wonder if I am banned for life…
