Yesterday had the worst smoke haze day here thus far, but still very mild compared to Melbourne, Canberra, etc. All my scopes are capped up, and covered with sheets, and my eyepieces are in a case. If smoke got as thick as fog like has been seen in Canberra et al, I think I would wrap all my optical gear up in my spare bed sheets, blankets, pillow cases etc, and shut all the windows. Would likely have to turn the aircon on depending on heat, but hopefully it would filter out most of the crud. How good are split systems at filtering out crud? We've had some thick dust storms here lately, and none of that crud made it through the aircon.
Smoke not forecast to get bad at any stage here, but no observing, there is still haze in the atmosphere constantly lately.
