Fires, can't live with em, can't live without em.
If the smoke is causing extinction, that's a perfect excuse to buy a bigger telescope.
Fortunately, out here most of the smoke from stubble burns is in the big cropping areas SE of here and with the predominant north westerlies, blows away from here and down towards Yass Canberra and where there are no telescopes or observatories. The mountains around Canberra also very kindly holds back a lot of coastal cloud keeping things clear out in the Central West.
