    My 8300M seems to have a dust mote. It appears with different filters. How can I get rid of it?

    Given the size of the dust spot, it's not anywhere near the chip. Knowing the f/ratio and the pixel size of the camera, you can estimate how far the dust is from the chip.

    I'd check the front window of the camera, and any optics immediately ahead of the filter wheel (corrector, reducer, etc.). A can of compressed air would be the first step...
