Anyone confirm what this white dot is? F22 dust check photo enlarged to 100% - I suspect dodgy pixel??

Are pixels round?

[FurtiveFreddy]

It seems to be iris-shaped and I would suggest you'd see more pixelation around it if it was the size of one dead pixel.

Are you sure it isn't a UFO?

It appears to have seven sides - presume your lens has 7 iris leaves? Might be a clue.

Some of us are but it's a lifestyle choice.

Yeah. That's Hot Dust, that is

Is it the missing part of comet Ison?
