    Can any one explain this image to me? are the green lines separating 2 images?

    The two green lines are #satellitetrails, or possibly due to a distant aircraft which passed through the field.

    The red star is indeed a star; the 'shell' around it and the four-pointed star (lines) are #artifacts, caused by light from the star bouncing around inside the camera (and off the 'spider', the four vanes which support the secondary mirror in the telescope).
