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...

Wow Don! This makes me curious about seeing the progress the longer the grass stays in the mudpuddle. Keep up!

Ah I see, thanks for your response

Stunning video, do you have a 4k version available to watch somewhere?

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...

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...

Thanks,

Yes I did, I got one second hand for cheap. 30 mu.

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...

Okay wow, thanks apochronaut, you seem to know a lot about this. I'm not sure I can understand all of it but I'll keep what I can in mind. Martin Kreutz, from https://www.mikroskopie-forum.de/ seems to get good results with water immersion on his U-TLO. But I'll have to take a closer look at his set...

Hello, I just wanted to give a quick update regarding my eventual decision. I did end up getting a 60x UPlanSApo water immersion objective at a friendly price from a forum member. It was still a lot of money so I was dreading on it day and night for some weeks. I have been using it for over a month ...

How very interesting, thanks actinophrys.

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...

Ah thanks actinophrys. Interesting that they display such sexual dimorphism. I'll try and see if I can recognise the male next. Anomalous Mating. The males of A. brightwelli have been observed to mate with other males, newborn females, and with other females two and three times their own size taken ...

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...

Thank you for the kind words, I'm working on a little video of these rotifers as well. Will post in sometime next week. Will be available in higher resolution than these photo's here. Check out the images on Flickr for the 4k resolution.

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...

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...

Hi Synnus,
I managed to make a deal with someone on the Olympus Microscope User facebook group. Waiting for it to arrive now.

Thanks!

Thank you very kindly for the links synnus I am also frequently checking ebay so I am running into the same links that you are. i appreciate it but I will continue to check every now and then so you don't have to go to the trouble of sending me the links, but thanks! I'm trying to make some deals he...

Thanks synnus. I was trying so hard for that last link you had sent. I was watching it for a week but at then suddenly there was a problem with my ebay when the auction ended so it ended up going to a very lucky person for 460. Seems very low to me. Well the rest of that day I was so disappointed an...

Haha I agree that this time it might not look much more interesting, but it is a good idea I hadn’t thought of before.
Thanks Squintsalot

I'm so very glad you enjoyed it! I have had the pleasure of meeting merlin on a couple occasions and he is truly a joy to speak with. I love it when somebody is able to dive deep into a paradigm, yet still retain a sense of humor and wonder. There's few people that you can talk with about nothing bu...

Thanks for the responses. I guess I’ll have to spend some on those cubes that pass only uv or uv+blue.

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 ...

So I guess these might be photographs of aliens... Cool.

Hope you enjoy it Michael! Let me know what you thought Apochronaut take a look at this: https://www.sciencedirect.com/science/article/pii/S0019103506004143 So supposedly, it is possible that during a meteorite impact a piece of rock covered with lichen was flung into space. And because the lichen c...

Ah that is unfortunate Don, I can imagine that the precise skill of microscopy could be a challenge. I hope there are some good things that come out of it too. I'm happy you are still enjoying microscopy, though! And now that you say it, I actually like the shallow depth of field as well. It kind of...

Hi Don, Nice photo’s! Plants contain the most beautiful secrets if we just care to take a look. I noticed you posted a series of pictures of a stomata, each containing a different point of focus. Have you looked into image stacking at all? You can combine a series of photographs into one where the w...

Hi Hobbyst46, I guess I could have indicated a little better yes so here is a little list of the specific illuminations: 1. Reflected LED 2. Reflected UV: excitation 530-560 nm; emission wide 570 nm 3. Reflected LED 4. Reflected UV: excitation 530-560 nm; emission wide 570 nm 5. Reflected UV: excita...
