You are correct Jason it is the same ota with the Quadruplet reducer/flattener!
Just as a package deal.
With the long weekend I managed to make the adapter plate to match the Tak quick release bracket and the Arca Swiss mount.
Needed extra height to clear the focuser housing anyway.
Only fixed using 1 screw until I align it with my TSA ( may have to face the adapter for alignment and then I'll add the second screw.)
Simple.
I thought I should add a photo just for Col
