Adjusting SRA using macro lens vs microscope

I have ordered a USB microscope to adjust SRA after reading Fremer's article. Meanwhile, I took some pics of the stylus with non macro Canon L lens (handheld) and can visualize the sharp triangular shape of the stylus and the record surface. It is only reasonable to assume that with a tripod and macro lens, the image would be much better.

Since many audiogoners are expert photoghraphers as well, anyone tried this?

May I respectfully direct you to my own article on the topic from which, I might add, Mr. Fremer borrowed (stole?) liberally over 4 years later!!

Thanks

Turn the setup 90 degrees, one could "ballpark" their azimuth as well.

Thanks for the good read. With a 10x lupe and backlighting, still quite difficult. I will see when the scope gets here
