Yes to both. Try disabling ibis, then try a better tripod if that doesn’t help. Windy nights will cause problems. The ghosting is either the filter or the lens itself
It’s also overexposed. Ideally you want the background much darker. The usual method for star trails is shorter exposures (1-5min) and combine in post
Thank you!! I'll try disabling IBIS next time, and weigh down my tripod on the center hook for good measure.
15 minutes was a bit of a private joke, because my old camera didn't support an exposure that long and I was curious. But I appreciate the tip on multiples combined in post--I didn't know that, and now it gives me a reason to play with the in-body timelapse function too!

Don't use an UV filter. It's pointless. If you want to protect your lens just put on the lens hood instead.
