I made one of those for my DSLR, I am using an OAG now so it doesn't fit on my DSLR anymore. It screws onto the bottom of the camera, I'll give it a go on my 120mc and see how it goes.
Ok I tried it out for an hour, the temp went from 26 deg to 11.7 deg in 30 mins and then stayed at that temp for the next 30 mins. The outside case and nose cone had a lot of condensation but the optical window seemed fine. A partial success but I think that the condensation might become a problem during a long session.
