Overlaid objects?

  • lpspieler by lpspieler

    There are two objects in this image set that do not move in a straight line (but similar to each other).

    Is this an effect of overlaying nearby objects (maybe in combination with earth rotation/movement and telescope pointing)?

    Seen this once before but forgot to mention it here.

    Yes, those are artifacts that are due to a general telescope positioning/pointing habit.

    See here (+follow other links) for more details.
    (The general consensus is that these artifacts are related to dust particles inside the telescope.)

    The general related hashtag would be #artifact.

    Mind you. this type of artifact can be seen in a lot of images.
    (or ... specifically hash-tagging them would be somewhat similar to hash-tagging #stars.)
