Star filter?

Nope, no filter at all. Just the lens flare.

Its interesting... My camera, without a filter, shows bright coronas with 14 rays around it. Yours shows quite less... That's why I asked.

I would assume it depends on a LOOOOOOT of factors. Including specific materials lenses made form, sensor matrix somposition and arrangement, everything, essentially. Maybe even weather. Likely, the lens iris and shutter, too. And maybe shutter speed and aperture. And gremlins, of course. No electronics is complete without a crew of those bastards :)

What's funny, my own eyes give 6-rayed lights, too. Or is it my glasses -- I forgot :)

And what's even funnier... In the campaign world I GM in, Sun is six-rayed, though it is unrelated.

Oh, and you totally should post some spectaculatr example :)

Well I have this right off hand. They are street lights... I need to find a nice picture of the sun for a more accurate depiction.

I am not sure (as in, needs checking) that street lights produce the same flare patterns as the Sun does. Same applies to all of the above, too -- everything is a possibility which I didn't check to confirm or eliminate :)
