With blur at the terminator, I don't know if it's dust, but it seems like it XD without tracking/guiding.
M81 close-up
Photo description / processing
I'm not sure if this is dust. Comparing it with other photos, it's hard to say—there are some similarities in places, but not many. There's some trailing because I didn't use dithering, and I shot without tracking or a star tracker.
