Rik,
Although I certainly use coverslips for water mites and daphnia, in this case I did not. The plant itself was too wide. The structures themselves were tiny, so the welled slide was deep enough to put them under water completely.
Maybe some explanation about the setup is requiered. I'm a general wildlife photographer with an interest in left-over subjects. Things my collegues don't like to picture. I do picture birds and landscapes, but I'm quiet known for my bats in flight, fish, troglobites etc.. Each year I tackle an other subject. At this moment, it is macro beyond 1:1. I try to picture my subjects with the equipment I have. I had to buy the optics of course (made a nice deal with Javier seta666), but someting as cool as the Bratcam is overkill for me as this is just temporary. Next year, I 'll probably try to picture flying bumblebees or canopy beetles or something.
So, I made some kind of darkfield system of a box and used one of my tripods to support the camera with the stackshot. If someone has a real darkfield-thing on surplus, I'm willing to exchange it for my box
Some other species I made with this system are added below.
