I was reading the wikipedia page on laser light, and on a linked article, I saw this image:

What is causing those red specks to appear? I'm thinking it's the dust on the out side of the camera lens, but then why would some of the specks seem to be so in-focus? While the camera is focusing quite a few meters away.
