Long exposures can be used to achieve a number of things. I know the post has ended, but thought I'd throw this shot in to the mix for fun. It is a single exposure, of 16.7 minutes.

16.7 why not even
Your reply is a bit obscure, but I believe there's a question or two in there.
The "lens" was an 8" aperture Schmidt Cassegrain design telescope with a focal length of 2032mm at f10. While spending hours, even days, using software to combine many comparatively short exposures into one is currently all the rage; I enjoy capturing deep space objects with a single click. How they got there is up for debate.
