Green line?

    I have seen this green line before. Is this part of the instrument? Is this a marker? I don't know how to answer for it.

    It's a satellite trail.
    The satellite reflects the sunlight and because of its speed it gets caught in just one filter.
    Satellite trails can also be blue or red.
