Is this dust on the lens or the filter? Or something else?

What f-stop was used for the test shot?

It looks you've got the bigger stuff. The image is way too small for us to be sure that all the small debris is gone.

If that's a 100% crop, then i'd say looks pretty good. ;) There's one minute spec in the very top right-ish.. but wouldn't be noticeable at normal crops.

I can live with that one (had to go back and look) :-)

If you can't see anything at f11, You're good. A brand new camera would probably see some specs at f22.
