I did intend attaching something - now attached.

It is easy enough to ensure that the air between the sensor and glass is dry by leaving the assembly in a sealable plastic bag with dessicant for a while and then sealing with silicon. That worked perfectly for my 1000D cooling mod. The problem is keeping the outside face free of condensation.

I'm looking at a heat source that will fit into the very tight space between the shutter and sensor face. Nichrome is thin enough. SBIG do the same with their ST-8300, installing a small strip heater adjacent to the outside glass.

This should provide a localised warm region around the face of the filter - that's the theory? Open to suggestions.
