Another totally gorgeous video of beautiful life forms! Thanks!

Beutiful video! I have a question. It possible to make rheinberg filter for 40x objective? Or 20x objective is maximum? I'm trying to make dic-like filter, but it works only on 9x

I believe it would depend on the NA of your condenser and the NA of the objectives. The condenser NA must be higher than the objective NA for darkfield (and I assume Rheinberg) filters to work. Also, the higher the magnification, the more precise the entire filter/optical path must be. I believe that most people using DF and Rheinberg with 40X and higher objectives are using dedicated condensers with these systems built in.

Isn't THAT interesting: at 1:37, the tiny lifeforms swim around the Gonium, leaving a geometric space around them! Wow!

Yes, very cool. Like the organism could sense the highly moving environment and navigate through cleanly. Nice catch seeing that!
