I collect samples from everywhere, but most them come from this pond 30 feet from my backyard.
This is my main transmitted light microscope. It can do standard brightfield (BF), darkfield (DF), polarized, oblique, and DIC illumination. I use a mix of apo and fluorite objectives.
This is my main reflected light setup. It can do epi DIC and fluorescence. It also accepts most of my old Nikon, Zeiss, and Leica objectives.
