Watch as I disassemble and attempt to clean the field lens on my Nikon E600 microscope.
UPDATE: dust speck ended up being on the relay lens directly below the camera f-mount. I thought I had rotated it earlier, but I guess I must not have. Problem solved!
UPDATE2: I discovered I can remove the top cover on the field lens with a tiny eyeglass repair kit screwdriver WITHOUT removing the turret and stage. Much easier.

![How to Travel by Plane with Photography Gear as an Advanced Hobbyist or Semi Professional
Watch to learn how I travel on planes with my photography equipment as an advanced hobbyist or semi professional. I make a little money here and there, but photography is not my primary income. As such, photography is usually a secondary goal of my trips. I think I have a unique kit and I wanted to share it. More specifically, this video describes my chosen baggage on a ski vacation to Banff in Canada with a secondary goal of photography.
