    There is an image in the background. Can you help me identify what it may be? Thank you

    My guess is that it is part of the flat field that is subtracted from all images together with frames 3 and 4 being over-exposed, allowing us to see this variation stand out more from the general static noise. Notice how the images that shows up in frame 3 moves to the left in frame 4 about the same distance as the hot-pixel like artifact found in the bottom of the image about 1/8th from bottom above the 2 button. My guess is if you overexposed images 1 and 2, you would see it in there too with a similar movement pattern.
