Adjusting SRA using macro lens vs microscope

I have used a magnifying glass, and a comparison to an index card that has a vertical line and 92 degree line on it.

You have to "squint" for a hour, and have a micromiter head
height adjustment(like some VPI arms). But you can get close!

This gives a good starting point. Then follow through with very, very, small incremental adjustments, and a good "Ear".

You can hit the exact SRA in an afternoon.

A macro lens should work better!

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

I never thought of that.

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