I have seen a similar thing in the past with SBIG STL11 cameras.
That line is a bit fatter than what I have seen so maybe not the same thing.
What it was with the STL (its really the chip not the camera)
is that some types of Kodak chips read the pixels one row at a time.
So a hot pixel can appear to be dragged down the image forming a brightish line and starting at some point in the image where the hot pixel is.
In this case it appears to be that bright star so again this may be something else other than a hot pixel being dragged down the line during the readout process.
Those lines are annoying as even though they are supposed to disappear with darks and bias etc I found they often reappeared later in the processing of images requiring Photoshopping.
If it is a hot pixel it will do it routinely over and over and not just a once off situation so there's your clue.
Greg.
