Total desperation shot of my sensor dust. This is after I cleaned it, and although it looks terrible, I had to process this a LOT before the dust actually showed up. I'm not worried about my images, as the lens I'm using only goes up to f/16, and what little dust there is will be so out of focus it won't be noticeable.
In this image, however, the dust looks kind of like moons of Jupiter, I think.
