I'm seriously thinking about getting one of those little flip over telrad dew shields - even if it gives me a few minutes more use it'll be worth it.
There's a basic and deluxe model!!

Once the dew sets in your observing night is over!! Telrad is always the first to go,then 8x50 finder and then the EP.
A back copy of AS&T had an ad for Sirius Optics in Underwood selling Telrads and accessories.
Give them a call.
Cheers
