I’ve been cleaning the outsides of the Cooke Troughton and Simms polarizing microscope objectives all day today while I’m waiting for the paint to dry on the stand. Not really difficult but time consuming. The outsides are filthy. It’s taking about 2 hours to do each one.
I have used about 100 cotton buds so far. I have to make sure I don’t get any polish on the lens. I’m quite good at nimble fingered stuff. I can get within about 2mm of the lens confidently.
Can you tell which ones I have cleaned? ha ha! Oh, and don’t worry, I haven’t stripped the paint off the 20X by accident. It didn’t have a painted band to start with.
