There you go, something else I learned today, Dew Shields, I had no idea they existed, thanks Dennis. The binoculars in that image look no larger than mine, or not substantially anyway, I have 20x80 triplets, so would a dew shield be available for me, would I benefit from having them, given the rapidly cooling conditions I might expect, particularly as cooler weather is approaching?
One again looking at that image, the dew shield appears to be some sort of flexible material, thick cardboard perhaps and held in shape by electrical tape or similar. Would a device if I built one (two, one for each eye), have any real practical benefit? In other words do they really work? Or do you have to have a battery powered one as you have described to be effective?
