What size filter to use, 1.25" Bino and 2" diag ?

I want to buy a UHC filter to use with my TV Binovue. This binoviewer has a 1.25" tube which requires a 2" adapter to connect to the diagonal.

There are a couple of 2" EPs in my kit which can't be used in the Binovue, so I'm already getting a 2" filter just for those.

I'm fairly new at this and confused on what filter combo I'd need to accomodate the 1.25" Binovue. Would I need to get two 1.25 filters, one for each EP, or maybe just one 1.25 for the Binovue, or can I use the 2" filter ahead of the diagonal somehow ?. I'd much $$ prefer to use the single 2" filter for both cyclops and binoviewing if possible, barring that a single 1.25 on the Binovue, even if it takes some additional connector of some kind.
