The result is awesome. How did the dust come out on the duoband? Or is it such weak oxygen? The "little ball" is there too and for some reason draws more interest)

Not dust, oxygen.
And I messed up with the bubble — it's not visible on single frames, I thought it didn't fit in and ignored it.. In the end it turned out to be at the very edge of the frame (( if only I had framed it a bit differently
