Problem:

The streak running through the image is either a meteor or satellite. The monotonic change in brightness over the extent of the image leads me to believe this is a meteor. Satellites frequently exhibit periodic changes in brightness due to their rotation as they cross the field of view.

Fix:

Take enough images of your fields so that upon combining, streaks like these will be removed.
