Hi Suavi,
I agree. I had a beautiful TEC110 F5.6 oiled fluourite triplet that I now regret selling. But its focuser was one of the first TEC engineered focusers and it was too light weight and I should have swapped it out for a Feathertouch. But if I screwed everything down tight and supported the end of the scope on the focuser side I got round stars in the corners with the 16803 using the TEC flatteners (TEC flatteners are like Tak - they work).
Greg.
