The following pictures show three telescopes which will break down into 3 main sections along with a number of 'struts' which can be held together in a home-made bag for ease of packing. This type of unit can be assembled in just a few minutes - but is very compact for packing into a car or small S.U.V. for transport to a dark site for better viewing.
The first (and larger) is the Author's 12-1/2 inch, which can be broken-down into three sections, a base, a 'mirror-box' and thirdly the upper cage section. Weight of the assembled unit is 50lbs (approx 23 Kg) The mirror is 19lbs.(approx 8.6 Kg) The struts are aluminum 5/8" square tubing some 38" long.
The second pair of pictures illustrate the construction of this type of "Dobsonian" telescope. This one is for a 9 inch mirror. and is now completed. This weighs only about 20 lbs(9 Kg) as it has a light-weight mirror. (Port-hole glass) The tube section has the struts permantly attached, and fits with two 'suitcase clasps' to the mirror box.
