Using a loupe or magnifying glass to check stylus angle, etc. is always a problem for me. First, my eyesight isn't what it used to be and second the circumference of a loupe makes it difficult to fit into the angle of the cartridge and turntable (at least for me).
My solution was to purchase a pen microscope with 25X magnification. It is, as the name suggests, about the size of a pen so I can maneuver it into tight places and the 25X magnification - you can get higher - helps my old eyes.
