Small red lines (#artifact)

  • luanee by luanee

    Two small red lines just below the galaxy. I assume they are just artifacts, but most of the artifacts I've seen are lines that continue off at least one side of the photo and/or are perfectly straight lines. Does anyone know what causes these lines?

    Straight lines that go off the page are from bright stars. These red lines.. well actually I don't know. Maybe a satellite, but they must be far from Earth. Satellites are usually brighter. Possibly fast moving asteroids. I have been calling them cosmic rays hits, but those are usually more irregular.
