This may be a world thing, a viewer thing or a settings thing, I'm not sure. I've seen it other times through the years too, it just seems more noticeable lately and I'm not sure what causes it so I thought I'd ask. I changed viewer settings around the same time I upgraded to an 8x8 so it's hard for me to know the culprit.
It looks like a very thin blue layer in the sky. Does anyone know what causes it?
