The stars are streaked because the mount was tracking the comet.
The comet was moving north, toward the top of the image.
So the stationary stars appear to be moving south, toward the bottom.

Most Comet images show dramatic comas and tails.
But the image above shows how many comets look in small telescopes.
These 4 comets were imaged the same morning, between 4 am and 5 am.
They were up there in different areas of the sky hiding among the background stars.
