Welcome aboard!

Yes, there have been good reports using a Nikon CFI Plan 10X objective with Canon 70-200mm f/2.8, especially at the long end near 200 mm.

I believe that lens has a 77 mm filter thread.

I am not aware of a one-piece adapter that will go from 25 mm for the objective all the way to 77 mm for the Canon 70-200.

So, you will need an ordinary step ring plus the objective adapter.

Because you are already using a Canon 100, I guess that you already have a one-piece adapter from 25 mm to 58 mm, or perhaps a two-piece setup such as 25 mm to 52 mm plus a step ring for 52 mm to 58 mm.

For the 70-200, I suggest just getting another step ring, either 77 mm down to 58 mm if you currently have a one-piece adapter, or 77 mm down to 52 mm if you are currently using the two-piece setup.
