Yes Luka i used an MC Clear coverglass over the sensor, and i sourced it overseas from Astonomik directly. I also have another MC Clear barrier by way of a Astronomik MC Clear EOS Clip-in filter in the mono camera, which is sealed in place to provide an argon chamber ahead of the sensor. However, i would not exoect everyone to go that far in condensation protection. Because i am imaging from my observatory, i need the camera to be able to run for six hour sessions, and keeping the optics clear is a necessity.
On long imaging runs I do sometimes run into a problem with cold soak, where the cold transfers through the scope adaptor to the front mounted UV/IR Cut filter. The front filter is exposed to the atmosphere and can get some fogging on it. Inside the front filter is the argon chamber so it can only fog on the outside. The answer would be to heat the external facing adaptor filter but i never got around to that, i have used a heater strap wrapped around the focuser barrel to transfer heat to the camera adaptor barrel, that seems to work ok.
Rowland worked on a couple of internal heating approaches in his thread, worth reading.
