I put the 16 inch scope together for the first time tonight. The six truss rods attach with bicycle clamps, collimation knobs and a power button for the fan at the top of the mirror box. I’m going to shorten the ground board legs and the truss rods a bit before I’m done. The six truss rods are connected to each other and as identical as I can make them. I need to add a bungee or something to keep them together while attaching. Plenty of fine tuning to do.
