Can't get much bigger than this (aside from the accidental capture of a far-off universe in a night photo):
This is the first time I've photographed the sun as a subject. Only used a UV filter, and dialed back exposure to -2 stops. That little dot is a sunspot, about 11 times the size of the earth. I needed to take multiple photos with the sun in different positions just to confirm that it wasn't a speck on my lens.
The smoke from forest fires has made midday feel like a third world country with lax pollution controls. A week ago, when the smoke began blowing in, it triggered memories of coal smoke from villages in Tanzania and the pervasive smog in Beijing. Fortunately for us, this should scrub out the first rainfall, which some weather reports are calling for in about a week's time.
