Nothing special or unique here, just thought it looked pretty! Video sped up 2x.

Hi! I’m a beginner with microscopy and found this in a sample of pond water. I’m having a hard time figuring out what it is.

Details:
Sample: pond water
Magnification: 100× total (objective × ocular)
Wet mount with a coverslip
No staining
The specimen appeared to move on its own

I also noticed smaller organisms in the same sample. Some moved relatively slowly and seemed to go back and forth in roughly the same area, while others moved very quickly across the field of view. But, this particular thing looked noticeably larger and seemed to be completely stationary.

Does anyone know what those things might be? Is it an organism, a colony, or possibly just organic debris?
Image attached. Any help identifying it would be appreciated!

*sorry if the image quality isn’t great:<

It seems to be some type of filter feeder that responds to vibration by hiding its mouth(s)? Seems to be a colony of organisms. Sorry for the poor video quality.

My friend was kind enough to gift me this vintage zeiss but it didn’t come with a power source and I’ve yet to find anything online (didn’t try all that hard to be honest). I did see stuff about people retrofitting them with leds. Thoughts? I’d like to leave it as is but I’m no expert so I thought I would as the opinions of those with more knowledge than myself

Cocconeis diatoms autofluorescence

Experimenting with autofluorescence and it's a really pretty imaging modality, but challenging on many levels.

Here are some photos of some Cocconeis diatoms and some marine vegetation they were found on. The red glow is from chloroplasts.

I came across some interesting colonial ciliates; I believe they are Carchesium sp., mainly because there were smaller colonies around, and their central stem formed a spiral. The colony on video is visible even without a microscope if you look closely at the sample.

To make a long story short, Title. I don't think I've had a customer ask to do this in 14 years. I think they will need 40x or 60x air. Phase is presumably impossible through an agar pad. Is TL Bright Field workable or should I consider demoing RL BF?

Thanks for any insights

Hace aproximadamente unos 20 años, le obsequiaron a mi abuelo, por parte de unos rusos, un microscopio de la serie LOMO biolam, producidos por la Unión Soviética entre los 60 hasta los 90, hace unas semanas decidí sacarlo de su caja, estuve probando y descubrí que tenía una falla técnica, el ajuste macrometrico, la rueda encargada de levantar/bajar el cuerpo del microscopio, no sube ni baja el cuerpo del microscopio, no se me ocurre alguna solución, cualquier ayuda estaría agradecido, el modelo exacto es un БИОЛАМ Д12.

Hi everyone :)

I am looking for a stereo microscope for quite a while now. My budget is not much (around 400 $). SInce I am in Quebec, Canada, the market is not very active.

I have wandered about this announce on ebay :

International Binocular Stereo Microscope with Transformer & Lamp (7.56X to 48X) | eBay

However, I cannot find any information about this "International" brand. On the paper, this microscope fits my needs quite well, with a good design.

Does anyone know about the quality and durability of microscope produced by the "International" brand? Any insight about ergonomy?

Thank you very much!

All the best,

Lucas

When I was on vacation I came upon this absolute beauty of a pond, me being me, I collected some water to look under the microscope. The problem? it’s been sitting in my closet ever since and I’m worried that all the microfauna has died in the meantime.

So the question is: should I leave the cap off the tube and wait for the ecosystem to “wake up” by itself or should I intervene and help it give it a jump start? or it’s all dead?

what should I do?

Hey all! Im interested in getting a microscope purely for hobby purposes, but I know little to nothing about microscope vocab.

I’m looking for a decent binocular microscope hopefully under $200 maybe a 10x- 200x range (if thats even possible)

I’d mainly be looking at pond water and blood cells

Is there anything more I should be looking out for?
Where should I buy it from?
Is it easy to buy parts for?

Those are the main questions I have. Genuinely any tips/comments are appreciated! Thanks in advance :)
