Pickup SRA - starting from a 500x microscope


I am not sure if my Lyra Atlas has the right SRA. Can other owners contribute? I have bought a 500x usb microscope, but it remains hard to find the exact angle. It is easy to get the angle of the record (or platter - I use a mirror), but very hard to get the angle of the stylus. I use the Cooling Tech software but it does not solve my problems. Trying to estimate the angle I cannot set the crosses sufficiently exact, and end up with values like 88, 90, 94 - varying all over the place.
I have only taken a few pictures so far, and could perhaps improve them. Tips and info welcome.

Interesting that the OP is trying to figure out a method for setting the correct 92deg SRA on an Atlas yet the venerable Mr Carr at Lyra ( for whom I have the highest respect and admiration) is not a great fan of SRA.
A bemused Atlas owner !
Thanks for advice! I dislike it, however, when an honest question is turned into a stupid statement. Rpeluso writes as if I've left my ears behind - I have not. Going the visual way is a "nightmare". Well perhaps not though I trust my ears mainly. And Sunnyboy1956, where has Lyra said that SRA/VTA plays no role? It is more that they try to adjust for some margin, in my interpretation - but J Carr would be welcome to speak for himself. "Not a great fan" - who is? Karl Marx talked about the world of neccessity. Few audiophiles "want" to go into this SRA microscope testing business. The reason they do it, is to get the best possible sound from their pickups. Same with me.
Dear Mr Holter, my apologies if my comments appear to be derisive or dismissive of your efforts. That was not intended. As an Atlas owner all I was trying to suggest was that you can achieve great if not spectacular sound with your Atlas without obsessesing about SRA. I made no reference to VTA. SRA and VTA are not identical or even interchangeable terms. There are many who believe that the efficacy of SRA is overrated notwithstanding it's advocacy by MF. YMMV
All the best
Thank you Sunnyboy1956. I do agree with you (and with Rpeluso) that too much adjustment can become on obsession. On the other hand, a bit of it is a needed. Since you have an Atlas - where do you set the arm - up, down, or just parallel?

Thank you for the joke of the year
