the tiny holes in the Nipkow Nipper film images.
We all have quite tiny holes in our standard Nipkows so working upon these with some precision does require a microscope which we don't always possess.
I didn't have one either but made one from one side of an old pair of binoculars and a 2" focal length lens....a standard eyeglass works well.
It was mounted on a crude stand, the binocular adjustment being used for the final focusing. As you see the eyepiece is just stuck onto the binocular with PVC tape
I do enjoy precision engineering
Piccys show end of a standard sewing needle and a hair from my head....
...now I'm even balder
