    Fogging Optics
    From: Rob Hansen
    Date: 2018 May 23, 07:37 -0700

    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
