wondering if anyone has any ideas about the effect of smoke on optics. I'm in Australia, and as you are probably aware we have had some truly horrific fires that are still burning. I live about 300 kms as the crow flies from the fires, but where I live over the last couple of days the smoke here has been horrendous. Visibility was officially down to 1.1km, though my impression was that in the particular area I live it was more like 4-500 metres. I have kept my scopes inside the house with caps on etc. I'm just a little concerned that the smoke will seep in through any gaps and cause damage. Am I being a little too paranoid?
