I had a likewise picture some days ago and today I've got again a picture with a sort of green line in it. What is this green line?

Satellites sometimes pass overhead as the telescope is observing and reflect light in a streak across the image as they pass by. They move quickly so their trails are always a single color: red, green, or blue. Sometimes you can classify the central galaxy, other times there is no central galaxy because the computer got a bit confused.
