this point was made in post #8 and re-inforcing has never been done on GSO RC. I think you are confusing this with those that have Newtonian scopes and since their focusers are off axis they need reinforcing due to lateral stresses.
Depending on the temperature drops during the night my Metal tube 10" GSO RC only needs one tweak generally an hour after starting imaging and I bet thAts about par for the CF tubes as well. I spent my money on a better focuser.
