Thanks for your inputs,
I got some new ideas:
- replace the 300d by my old beloved CP4500 and a good EP, that should reduce the total weight to about 3.3 kg.
- a
Nextar DX mount. I'm not really fond of this plastic stuff but it fits the purpose, at least from the specs. It's here and in German

Has any of you ever seen/tested this mount before?
Cheers
