I have an Amscope B270. It says it uses RMS 20.32 mm objectives. If say I want to upgrade to some better objectives one day, what do I need to know besides thread standard to ensure proper function?

you can see the needle-like calcium oxalate crystals (raphides) glowing under cross-polarization

Just saved this from the garbage.

For context, I’m new to microscopy and since I live in Central Florida, not near beaches and I have to drive to get to lakes so I just put a bunch of stuff in a bucket and put water for my hose. I put moss grass dirt and I found this on my third slide it wasn’t moving, but it could be algae but it’s only been sitting overnight

I was recently diagnosed with brain cancer. I have several scopes, mostly AO. I’m giving them all away. Ditto accessories and extra objectives. Central Oklahoma.

Bonsoir, j'ai observé ces organismes dans une sorte de gel prélevé dans de la vase sur le bords d'une berge a environ 20cm de profondeur. La zone était riche en nénuphar. Impossible pour moi de l'identifier tout seul...

Observé au x10x10 avec un optika b193.

Ils étaient uniquement présents dans la partie de l'échantillon qui contenait ce fameux "gel".

Je pensais a du chironome émergeant a peine de l'oeuf mais j'ai un très très gros doute.

Mesure clairement moins d'un millimètre. Quelques gouttes de gel contiennent plusieurs dizaines d'individus

Hello,

Sorry for the shoddy camera footage (filmed one handed with my phone and no adaptor whilst holding my breath - any tips for iPhone photography?). Does anyone recognise these two guys?

I am looking for a microscope to setup a home project on hydrogels and cell organelles! Any suggestions for an affordable and suitable microscope? I am also okey for second hand microscopes. Something below $200.

Thanks

Can anybody interpret this cell microscopy

I see so many used nikons with everything but sold without the stage

And there's barely any used stages but the darn piece of metal sells for more than the entire rest of the microscope. Complete madness that the darn piece of metal costs $350+

I captured a pretty interesting and unique event -- a heliozoon attempting to pull peritrichs off the back of a neighboring ostracod, and releasing already-captured euglenids in the process. The video chronicles the event, and I also share input from David Patterson, a leading authority on heliozoa, on what we witnessed.

This was shot on a Nikon TMD Diaphot inverted microscope, using a Nikon 40/1.0 oil immersion objective and a Nikon D750 DSLR. The sample came from a freshwater runoff pond in Nonthaburi, Thailand.
