Hello, I recently noticed that when shooting ISO 800 or above in the dark, that I get these little red pixels in my image. They always appear in the same spot in every picture so I'm guessing its something with the image sensor? I'm shooting with a D80. I haven't tried shooting with a different lens yet. The pictures were also with longer exposure. The first one was 22 sec, and the second was 8 sec. Any idea on what it could be? Here are a couple of pictures of what they look like. Thanks!
