Mirror mount use with 20x80?

Has anyone tried viewing off a first surface mirror (like the Trico machines Sky Window) through 20x80 binoculars? I have heard about good results with 70mm and below, but not much about 80mm+.

Thanks

I believe that the problem is that aberations start to creep in when the magnification gets to this sort of level. I was thinking about trying the same trick with Tak 22x60 Astronomers, but that's what I was told. I'm not sure whether the Oberwerk mirror is a better alternative or not.

Must say I'm surprised that nobody has come up with a good solution to this so far...
