Hi Robert,

> Again, thanks for the info. Yes ... the trick for me is figuring how to mount
a saddle plate to the top of the Mewlon rings. Once I've done that, I think I
have the configuration I want.

I'm not familiar with configuration of the top of the Mewlon rings, but I won't
be surprised if there's a solution out there. Worst case, you may want to check
out a custom solution from Precise Parts:

> And actually, I'm not thinking about "quick swap" from the Mewlon to the FSQ.
I'm actually thinking about limiting all the piece parts I need to drag around
to setup. I'm pretty sure that each night, I will do one setup or the other
...

I see...

answer. If a part (from Losmandy or BT Technologies or someone else) says it is
"Losmandy D Dovetail compatible" ... does that mean it is interchangeable? Or
are there different "sizes" of D dovetails?

Yes. Anything that says it is "Losmandy D Dovetail compatible" will work with
the Losmandy-sized dovetail plates and saddles.

Glad to help!
