I used a Nikon D500 camera body attached to my Zeiss Axioscope, with 10, 20 and 40X plan acrhomat objectives, images were processed in Photoshop and I used free software Digicam control to capture the images to my computer. With some of the images I stacked 4-10 images to increase the depth of field.
There is lots of neat stuff to photograph in the ponds right now - I encountered a Stentor bloom with literally thousands of them in my Petri dish of pond water.
