Rolf,
this looks great.

I only have a concern about how you fixed the doveplate to the central brace of your construction.. same as James.

I would use additional bars or plates, fixed to the trusses, or my central brace would have to be longer (wider).
I will have the similar issue with my own mount (EQ6 and fiberglass tube - the whole OTA weights 13 kg) and I intend to machine the conical insert (the one that is held in place by 3 grab screws on the EQ6 mount) out of steel - because this is the place where the components of the mount are stressed the most - possibly resulting in variable flexures, that may be the problem with autoguiding (depending on how the guiding scope is mounted, of course).
The balance I intend to adjust by existing additional counter-weight, sliding along the tube of my OTA.
