    Hi everyone!!
    Does anybody knows what is that line in DSS2 Blue?
    What is explaining of its appearing?

    Hi @specter123,

    That's satellite or asteroid trail. You'll see more of them, they're quite common.

    Unfortunately, I can't see the image just now. If you are seeing anything weird in the DSS images, they are probably #artifacts of the photographic plates used for those images. Following the #artifact hashtag will show you other examples, which I hope helps to answer your question.

    Taking data with a telescope is not perfect, sometimes you can also see dust motes, in the discussion boards at Common Artifacts you can find more examples. Like here: http://talk.diskdetective.org/#/boards/BWI0000009/discussions/DWI00000ot
