    Ive noticed that at the greyhound and Sywell that the front lense on my BSA 10-50x60 is fogging on the outside of the glass, i dont have a sunshade is it normal or has my scope lost its nitrogen?

    I have noticed that after a while i cannot see where my misses are landing i wonder if this is a good indicator my scope is fogging up?

    Is it fogging on the outside or inside the scope?

    on the outside mate.
    Sometimes its hard to tell its starting to fog as the coating is a mirror type coating.

    Doubt it's lost the nitrogen, that would cause fogging on the inside I believe. is it only the objective lens or the eye piece or both?

    Not the nitrogen

    If it's fogging on the outside it can not be what the scope is filled with.

    GO

    Go into a motorcycle shop where you can buy a anti misting fluid to put on the lens . Or the old trick was to cut a potato in half and wipe it around it . mind you that could get a bit smeary . but it is cheaper . bit like Mr P ??? HOLLY:):eek:

    are you acclimatising the rifle before shooting, always a good idea to leave it out to cool down/warm up dependant on time of year, if you have come out of a warm house the gun case can keep the rifle and scope warm for quite a while!
