strange movement

    If you mean the dot near the center that moves up, down & right, then left, that is a #hot-pixel artifact where a single pixel on the ccd camera is incorrectly reading the max value (stuck in a full on state).

    The movement is caused because the camera is intentionally pointed at slightly different locations between frames so that when the set is realigned, artifacts will appear to move in a non-linear movement pattern like this. if this was not done and the camera pointed at the same exact spot each time, that spot might look like just another non-moving star.
