Asteroid Zoo Talk

    I marked the big light dot on the right side of the frames as an artifact because it looked like one of the black dots stated as artifacts.
    But the color of this artifact bothers me and it cannot be an asteroid since its trajectory isn't linear.
    So I'm calling for advice from more experienced contributors to know what this is.

    Its a telescope related artifact. (due to deliberate small telescope pointing offset's for the different time-frame images of a set.)
    Note the general movement pattern, You will see it often.

    (Although the search function is not what it should be, by using "exposure", "telescope" and/or, "telescope artifact" you might find some potential additional information on this.)
