Dust to dust ...

... is a real problem in macro photography ! 

Especially if you choose your subjects from places where things go to die :-/ 

So, this is a focus stack of 6 images taken with the microscope lens, slider rail, metabones focal reducer & microscope lens that I still know next to nothing about. See configuration shots in extras :-)

Colour today again - I tried a B&W conversion, but it didn't really work as the blue/green and the dust just blended into one.
