The first step is to gather the necessary materials. You will need a tube, a truss system, a tripod, a focuser, a secondary mirror, and a primary mirror. Once you have all of the materials, you can start assembling your telescope.
The truss system will be the foundation of your telescope. It is important to ensure that each part is connected correctly and securely. Make sure to line up the holes in the trusses with the holes in the tube. Once the trusses are connected, you can attach the tripod.
Next, attach the focuser, secondary mirror, and primary mirror to the tube. Make sure to adjust the focuser and secondary mirror to the correct position. You can use a laser collimator to ensure that the mirrors are aligned properly.
The last step is to attach the finderscope. This is a small scope that helps you locate objects in the night sky. Attach it to the tube and make sure it is tight and secure.
You are now ready to start observing the night sky with your truss tube telescope. With a little practice, you will soon be spotting galaxies, star clusters, and other celestial wonders. Happy stargazing!

The truss tubes were to be 12mm diameter aluminium tube, covered in black heat shrink plastic, it worked a treat. In one end of those tubes, for about 30 mm, I glued close fitting. , Building A Truss Tube Telescope.
