    Hi and welcome @Ciubeca 😃

    We have a lot of artifacts in this image so I will tackle them one at a time:

    • The green streak going through the image is a 'trail' caused by either a satellite or an air plane that happened to 'fly' through the field of view when this section of sky was imaged by the telescope;
    • The green background could be due to several factors - some possibilities - filter problems on the scope or the sky was fairly light when the image was taken (eg: astronomical twilight / light pollution);
    • The red and green circular objects are foreground stars - along with the above problems, the filters were slightly misaligned so we landed up the stars having weird colours and the objects being slightly extended.

    Here is the zoomed out version from SkyServer - the orientation might slightly vary, but it is the same patch of sky 😃

    Hope this helps 😃
