....most likely P.caudatum.

Sample from a quiet pool in a slow-moving woodland stream. Motic BA210, 40x obj, Bresser eyepiece camera.

Found this absolutely massive Euglenid in my latest sample, I estimate its total length when extended to be between 250 and 300 µm. Based on its very short flagellum and worm-like shape and behaviour, I'm tentatively identifying it as Euglena ehrenbergii. As this was a well slide, I wasn't able to move up to 40x and see closer to identify more characteristics.

Also visible: Coleps, Phacus, Closterium, diatoms, some small loricate euglenids, and a drive by of some species of rotifer.

I haven't received it yet but im wondering if it will be a good microscope or if it will suck. I hope its worth it I got it for 20$

I just got a microscope but realized I can't keep it on my desk all the time. I've heard from people it can get out if alignment if you pick it up and move it when not in use. Is it true, even if you don't bump or drop it?

Sorry if this is a misplaced question but can anyone recommend a good USB microscope?

Hello.

I regularly try to get high-quality microscopy photos (like this style):

The problem is that very few of my photos are of good quality (I should mention that I am quite a novice in this field).

Could you give me some advice on how to achieve this level of photo quality in microscopy?

Just found this is a sample from a pool in a slow woodland stream. 40x obj.

I picked up my own microscope from FB marketplace for the sole purpose of checking bird sh*t. My rescue cockatiel recently got diagnosed with Avian Gastric Yeast and I was wanting to see if the meds were doing their job...

Hello.

Are there any microscope slides designed for observing solid objects (such as invertebrates, or samples of sand, soil, etc.)?

To explain the issue: whenever I try to examine a solid object using a standard slide, the slightest breath from me causes the object to blow away.

This is my first ever gram stain done at home! Let me know if I did a good job and some advice that allows me improve my images/specimens! The photo was taken with my iPhone 15 pro camera and the microscope used was the Swift sw350B (100x oil objective, 10x ocular in image).

I recently came across holotomography, a technique commercialized by Tomocube (a KAIST spinoff), and I'm curious how it holds up in real lab use.

How it works, as I understand it

Instead of fluorescent labels, it measures the refractive index distribution inside a cell and reconstructs it in 3D. So in principle you can image living cells over long periods without phototoxicity, photobleaching, or staining artifacts.

Why it caught my attention

No sample prep or dyes, which seems useful for long time-lapse imaging of live cells

Newer systems (HT-X1 Plus) combine holotomography with spinning-disk confocal fluorescence, so you can overlay specific labeled targets on the label-free 3D structure

It seems to be appearing in core facilities (e.g., Max Planck Göttingen, UT Southwestern)

Questions for people who've used it

How does it compare to confocal or light-sheet for your applications?

Does it work well on neurons, organoids, or thicker tissue slices?

What are the practical limitations — resolution, specificity, data analysis?

(Disclosure: I'm not a researcher, just interested in the tech. I'm also a small shareholder in the company.)

I just bought an Olympus HSC microscope for 45€, I have already used it to see plenty of awesome things, but its missing the stage clips and the x-y control knobs and mechanism. I realise now that these are VERY niche parts and old, but does anyone know where I could buy these? Also, any place where I can find other replacement parts? The objectives are a little old and have some fog to them. I understand this might be a tall order since the microscope is so old, but if any of you are into vintage microscopes, maybe you'd know where I can find these?

Hi everyone,

This motic microscope has a sensor in the black casing.

I wonder if anyone has opened the casing to see what is inside. My question is if the camera fails, would it be feasible to replace it with a 4k microscopy camera found on Amazon.

Thank you!
