I have a question
I use microscope objectives mounted on bellows and a raynox 150 as a tube lens.
So no microscope.
Now I would also like to take darkfield photos is that possible with this setup? Do you have ideas how I can do this and what else I need to do so that I can record a water fly.
thanks in advance for your help
Regards marco

A ring light can achieve this quite well, if you get the distance from the subject right. Do this by trial and error.

Marco, welcome to posting!
The advice you've gotten from Johnny and Mike is excellent. I'd add that getting a darkfield effect in an open macro system is pretty easy. As the others have said, experiment with light placement, but with the light never hitting the lens. You'll get it quickly.

Here is one way of achieving dark-ground illumination without a microscope:
Inside the 144 LED ring-light is a disk of black card or velvet.
The specimen (a slide in this case) rests on a piece of black foam board with a circular or rectangular hole.
The foam board is supported by a kitchen bowl with its base removed.
Here is a photograph taken with this arrangement:
