Olympus BX60 3D model
Hello forum, I am looking for a 3D model of the Olympus BX60. I want to woodwork a case for transporting it, as well as design a number of 3D printed attachments for things like stage motorisation. To do this I require accurate 3D models of the stand, and preferably the BX stage (U-SVRB) model as we...

Re: First Days of a New Grass Bunch
Wow Don! This makes me curious about seeing the progress the longer the grass stays in the mudpuddle. Keep up!

Re: Is this a diatom?
Hi apochronaut, sorry for the late reply. I tried to find the original uncropped file to calculate the size, but I'm afraid I lost it. I'm guessing form memory and feeling that this was about 30-80 microns. Next time I see this I'll make sure to calculate properly the size, though I haven't calibrat...

Is this a diatom?
Hello, I found this round organism containing what appears to be chlorofyl c and the carotenoid fucoxanthin (the brown pigment in diatoms). Is there anybody that can confirm that this is a diatom? Found in a week old sample of a canal, with many more diatoms grown. https://live.staticflickr.com/6553...

A short movie about rotifers in Amsterdam
Hello, I was so mesmerised by the structures and behaviours of rotifers in the Amsterdam canals that I made a short movie about them. I hope it brings across some of the wonder that these creatures deserve. Enjoy! (Please use 1440p or higher, the rotifers are more beautiful that way.) tvflcNJrqYQ Mu...

Re: A giant rotifer in Amsterdam
This theory certainly seems worthy of an experiment einman. I do wonder whether rotifers are so complex that they might develop such a thing as a sexual orientation. I too wonder about all the little dynamics and feelings that take place around sex on such a small scale. I wonder so many things, but...

A giant rotifer in Amsterdam
Another sample from the canals of Amsterdam. I have never seen such a big rotifer, I'm guessing nearly a millimeter. In Dutch we call this raderdiertje, which means little radar animal. If anyone knows what species I'm curious. It's tremendously beautiful. 20x DIC https://live.staticflickr.com/65535...

These might not be the most impressive focus-stacks out there, but at least I gained some insights into the intricacies of plant reproduction. These are 10-20x objectives with desk lamp lighting. First are some very small mimosa flowers. Many tiny flowers form a bigger ball, I'm sure this has some c...

Rotifers from the canals of Amsterdam
I recently dove into the canals next to my house with a little plankton net. I found Synura algae and many different kinds of rotifers. I have no idea which species these might be but they display some interesting differences. Some were carrying eggs, some were motile, some sessile, all seemed to be...

Hey, so I was wondering if I can remove the excitation filter from a fluorescent filter cube, while retaining the dichroic mirror and emission filter to attain more autofluorescence. Let's say I keep a dichroic mirror like a DM505, and also an emission filter like a long pass 550 or something, this ...
