The Cube Dobsonian
I made this telescope because I needed a very portable, yet reasonably powerfull deepsky telescope.
Construction materials : 12 mm plywood, metal broomsticks for the trusses, and a handfull of screws :)
It started out by making the upper tube assembly, and the mirror box
To keep the mirror box as small as possible, the 2" crayford focuser is mounted
on a hinged focuser plate, so it can be swiweled in the space between the OTA wall
and secondary mirror for transport
The UTA, with focuser board hinges visible
Assembly and dissasembly is a very simple and fast process. It takes less than 2 minutes :
Loosen the bolts that hold the trusses to the OTA
Lift the OTA from the trusses, and unscrew the 4 brass bolts that hold the truss assembly.
They come off as a single part
Remove Telrad, fold the focuser and insert the UTA into the mirror box
Pick up the mirror box, rotate 90º and insert into rocker box
