    Uhm so what are these random dots appearing in the frames? They just appear in one, go away in another...
    And they are really prevelant in this set of images.

    That particular image imperfection looks like a hot pixel. There are a few pixels on the detector that read a very high value even if they're not seeing light. It jumps around like the observing plan does, but sure looks like single bad pixel to me.

    They'll tend to cluster in a particular set of image just due to the way the telescope points.
