Working on it.
Several ideas of creating a dry gas purged chamber in front with a clear optical window and using a smidgin of the warmed air off the radiator to blow across the external surface of the window to keep it from icing up.
Some silica in there might also help. The new setup has more room internally so I can hopefully fit a small bag or two inside.

I've also reduced the parasitic thermal loss with some insulation and reduced surface contact area at the junction of focusser and camera. The window will be ahead of that so it can be managed thermally seperate.
Fingers crossed ..

What do the commercial cooled cameras do to manage it ?
