Re: Wanted: Zeiss Jamin-Lebedeff Components
There was a long discussion about that on the German microscopy forum, with the general consensus somewhat supporting your idea. Of course one would need to do a bit of tinkering with the objectives to match the beam splitter/combiner azimuth. JL kits are among the most rare of the Zeiss items, stra...

Hello Michael,
Thank you for showing us your microscope. Did you buy it new directly from Zeiss? Also is this a gliding specimen stage?
Regards,
Wes

Hello Michael and welcome to the forum. It would be of great interest to me as Phomi III user (and others I am sure) if you show us your scopes and I am looking forward to seeing the protists that you have and will document in the future.
Best regards

Re: objective delamination.
Thats probably because there is nothing to delaminate there, no cemented doublets and such. Maybe Zeiss knew the cement they chose would lead to delamination eventually so they could sell new optics in the future, kind of like planned obsolescence.

Re: Where To Find Cyanobacteria
Put some soil in a jar with a bit of rain water. Add liquid plant fertilizer (may not be required depending on how nutritious the soil is). Close the jar and leave it somewhere warm with enough indirect sunlight.

Re: Diplophrys (Labyrinthulomycota)
Nicely documented thread Jochen, thanks for the link. Perhaps the species I found was in fact the one with colorless oil, and yes the filopodia did move slowly I'd say it looked as if they are used for crawling on the surface of the coverslip.

Thank you Tim and Francisco Do you put them back if they haven't developed enough? Yes, even if they are well developed I still return them after I'm done observing them. I was curious that the oil drop seen in this amoeba is not colored, as is commonly the case. You are correct, most often I find o...

Diplophrys (Labyrinthulomycota)
Captured via the floating coverslip method. You can see two opposing tufts of anastomozing pseudopodia, a large oil droplet and a nucleus adjacent to it.
