Hi,

if there is no condensation noted when running the camera indoors where its warmer, is it possible that there can be condensation when used outdoors where its cooler?
Initially, I used the qhy8 with just its UV/IR nosepiece on and noticed condensation on the outside of the nosepiece which went away with a dew heater strap.

Now I've added an mpcc with an extension tube and I assembled it in an air tight bag with dessicants and have not noticed any condensation yet on indoor tests for over an hour.
Assuming there is no moisture in both cavities (camera to nosepiece and nosepiece to mpcc), is there still likely to be condensation at cooler temperatures?
I don't suppose the air in the mpcc<->nosepiece area can get cooled by the glass on the nosepiece as that would be cooled on the inside with the air in the ccd area.
I'm hoping the mpcc/extension tube will maintain an air tight seal preventing moisture laden air from contacting the surface of the nosepiece glass.
