There is clearly a risk that it would not work out, but it would not cost you much to try it - you will need something like an EQ6 in any case, so the additional cost would be that of the tube rings and bar. If it isn't stable enough, sell the Dob and the tube rings and go to plan B? It's a possibility anyway. regards Ray

Thanks Ray. I have to do a bit more research and see what others have done. I remember having read about someone doing it on a 12" truss dobs (I can't remember where I read about it). A quick search has pointed me to the following thread:

Doesn't look too promising.
