Telrads... is there anything special about the glass?

[elusiver]

looking around at anti dew solutions for my telrad. When the thought occured that there's that anti-fog stuff u use on car windscreens etc. Anyone tried this? I didn't think that there were any coatings on the telrad glass so the anti fog stuff should really do no harm. It does leave a very slight 'haze' but being that the telrads a 1x finder it shouldn't really be of consequence. Any thoughts?

Worth a try :) Can't see any harm.

Here's one solution :D http://www.meridiantelescopes.com/images/telrad/telradhtr.htm

I've used Rainx on the Telrads window, it doesnt hurt the glass. But I found it's only good for mild dew. As soon as droplets form it needs to be wiped or blow dried and your back to square one.

looked at those solutions acropolite.. but i don't like the way they obstruct the glass. might give the antifog a try see how it goes.
