Depends on the Tak. I had an FSQ106, which as any owner will tell you requires an extender-q for most anything. I had to get rid of it before figuring out what gizmo would allow me to attach the AP diagonal I had. The FSQ is a specialty instrument, though, and has its own diagonal. I suspect most Taks would use the everbrite fine. I just saw a new ad in the refractor section for an FS128 with the 2" AP diag on it.
