I suppose I should put the caveat of that's whqt happens where I am. But I think because the mirror is so far inside the tube, it has the fans blowing air across it, the shroud around it, its not that exposed really.

Hopefully its the same for you. It hasn't been enough of a bother for me to get dew heaters installed yet.

Greg.
