    This line doesn't cross the entire picture...

    Hi Ludi13 and welcome to the Zoo

    The blue line is a satellite trail. The satellite reflects the sunlight and because it moves so fast it gets caught in just one filter Satellite trails can also be red or green.

    Hope this helps and happy hunting !
