Sure it is, but in the meantime, here are some photos of my Shelter 901 taken with a 500x USB microscope. I took these in my first attempt to get a handle on measuring SRA. It may look easy to take these snapshots, but they were cherry picked from about 40 photos kept from around a hundred taken with different focus and lighting while the USB microscope was strapped to the end of a shaky goose neck lamp to suspend it above the ‘table.
The back of the arm will not go low enough to get the SRA lower than about 3 degrees. Modifications are forthcoming.
Though the azimuth looked good to my eye with a magnifier headset, and the body was square with the platter, you can see from the photos how far off the azimuth was.
