Peter.... Use a cold finger inside the CCD chamber to control condensation... Basically, seal the DSI up so its air tight, and have a metal finger inside that sealed body that connects directly to the peltier.. That metal finger will get colder than the sensor due to it having no electricity running through it... any moisture inside the camera will condensate and freeze onto the cold finger as it will be the coldest surface in the camera.. Also a light clean of the sensor using isopropyl alcohol will keep the sensor from frosting/freezing...
Theres my thoughts for ya...
Love the image... Great scale for the ED80..
