Thanks folkfreak. No, I have not tried it with the lens guard removed. That may just be the ticket. Thanks for the tip.
Stylus inspection with USB microscope
I have been trying to do inspections with USB microscopes for a while now, and am having no success. I've tried a few, and just can't get the knack of these things. I have seen some extremely detailed examination photos on the web with the USB scopes, and can't figure out what I'm doing wrong. When I use low power magnification, I can get the cantilever into focus, but nowhere near the magnification level required to inspect the tip. When I use higher levels of magnification, I have to move the scope so far from the cartridge, that it proves worthless. Whats the deal with this USB process, and where am I going wrong? Wish I had an old Shure SEK2 like back in the day, but, alas, they seem to be like searching for the Holy Grail. Any help would be greatly appreciated.

I bought one for about $15 and got these pics. https://drive.google.com/open?id=1Dr01dc8Z3N8t4Cwr_OLOWGPSmPaIrLLE https://drive.google.com/open?id=1JpGR9DgWozHpbk-2IjsMXCmKlhGSHREQ |
It's a big PITA! Besides adjusting the magnification, you have to position it to focus and that focus distance varies on the amount of magnification. I got those from a cartridge that's not mounted so it was easy to position it. I tried on the one that's mounted in my tonearm and still can't nail it. Here's the best I've got so far after trying for about 30 minutes. https://drive.google.com/open?id=1bJwQYgRKvr2YZOrW2999BIFCkRjDC9BU |
