Mysterious black dot with star in the background

    What do you think about this?

    The black dot in the center of the star is an optical artifact.

    Hi Spirit59 -- this is an artifact. Basically this star is SO bright, that it completely saturates the camera. When this happens, the camera returns nonsense! (You can see this happen yourself using a digital camera to take a photo of the Sun).

    (Please note that using your digital camera to take a photo of the sun can potentially damage your digital camera. And don't use an optical viewfinder...)
