Default Red Dot and Streak on Images

Hello all,

Need some advice from some one a bit more knowledgeable than I. Here is my problem. As you can see in the pic I have a faint red line that ends in a red dot on my pictures (see below) If I didn't know any better I would think it was a laser pointer, but that is not possible with the multiple pictures and locations.

I have cleaned the lens, filter, and gently blew air over the CCD. I would think it would be dirt, but I am not sure...

The first is on the hood of my car just below the air intake. (the black dot is bird crap...dirty birds) On the second pic it is just below the cow catcher on the locomotive.

Any advice would be helpful!

Thank you,

It's likely a defective CCD causiing the issue. Sometimes sensor defects can impact an entire row or column of pixels, depending on the readout design.
