Hello,
The end of the sextant scope I look through tends to fog up in 30-50 degree temps and is especially noticable during twilights and after dark.
Do you folks have any suggestions or tricks you can recommend?
I am going to try some anti-fog products and see how it goes. Holding my breath may not be a good option as I am not super speedy at sight taking, plus I like to fool around shooting most of what I can find... It may not be my breath that is the main fog source anyway.
Thanks!
Rob
