I was hoping something like a fan would help to stop the mirror dewing up? (or slow it down at least)

Mike,
Like I said I was not trying to be too smart in my reply but if we are having a discussion on dew we need to include some of the basics so people new to astronomy can learn some of the more simple methods to avoid dew short of fan installations,etc.
Maybe I could have said it better but that was the intention.
Cheers
