How to get 100 accurate azimuth?

I thought he meant tape head azimuth?

You can play with the settings for hours or just get a happy medium and settle with it, atleast that is what I have concluded, but I bet folks can get it perfect if time and patience can both be applied.

Or maybe telescopes?

Hi

I am sorry about the mistunderstanding. I was talking about cartridge alignment;-)
Until now, I have done it by placing a Lego brick on each side of the cartridge body and used this as a visual guideline.
I am looking for a way to adjust azimuth so it's totally accurate.
I have found the Wally Analog shop, but it's a bit expensive so I was hoping some of you skilled guys had some experience to share.

this is just off the top of my head, but it seems like i remember reading somewhere a reference to a denon test LP that had an exacting method of setting azimuth. you may want to check it out. i may be FOS.
