Sorry, I read the post a bit too quickly... Are you planning to mount the Nikon piezo with a Nikon objective on a Zeiss scope? because of the size of Nikon objectives, maybe an older Zeiss mount would work better...i.e. find adapter to mount Nikon piezo on Zeiss scope, and then adapter to mount old Zeiss objective on Nikon piezo... these should both be possible.

Thor Labs may have such adapters...

Zeiss makes adapters from the old to the new M27 mount, so it should be possible to get similar adapters from for Nikon objectives on the new Zeiss scopes. In fact, I think Zeiss even has adapters to mount the new larger objectives on the older scopes. However, all caveats mentioned by Chris remain valid. In particular, Nikon objectives are huge compared to Zeiss (Nikon 60x/1.4 Plan Apo is about 2 longer than the equivalent Zeiss.
