Did you try cleaning the front element and filters? Looks like smears on either of those to me.

The filters and front element were clean. However, my ND filters seem to miraculously get some streaking when I use them, seemingly by rubbing together in the holder. But, if that caused this, wouldn't the streaking on the filters align with the streaking pattern in the sky? The streaks the filters get are not diagonal lines. Also, why would it appear on some photos like the one I posted a few replies above of the same scene that I took without filters while also not appearing on some photos taken with filters? I think that can be ruled out as the cause, but I appreciate the idea.

It would be reasonable to remove all filters and see if you can reproduce the streaks without them, to completely rule out the filters.

As I said in the post you quoted, the second photo was taken without filters.

Sorry, I missed that. Although I copied your  quote, I was actually thinking about your post with the actual second picture in it, in which you seemed to be saying you had used a filter.

Did you shoot both RAW and JPEG when you took the picture? And, if so, did the JPEG have the streaks? If you have not shot both RAW and JPEG together, it might be useful to do so to see if the streaks are in the camera produced JPEG or are a result of processing the RAW. Does the Tamron 28-200 have the latest firmware?
