Re: What accessory do I need to par focal microscope camera in trinocular tube of stereo microscope ?
Assuming that those adapters are the right threads/attachment, they should work just fine for your purposes. I have that exact same 1x one (though bought from aliexpress) and it works really well.

Re: Camera adapter Touptek FMA050 replacement to remove some chromatic aberration
Unless you can 3D print optical lenses, you will need to buy an apochromatic reducer, or use no reducer at all.

One of the first real results from my neophot 21
My neophot 21 is still in quite the state of disarray, realistically at some point I need to do a complete disassembly and clean, but as it is now, it works, for some results. So, here's a look at the quad bayer filter from an ipad pro 12.9" 2015 front camera. (model a1652) https://i.imgur.com/1qqEC...

Re: Everything looks better in slow motion
More or less, tho the inverse is probably more accurate, as it gets larger, approaching 100% of the sensor, the fps gets lower.

Everything looks better in slow motion
I found this in a sample of water, mixed with pollen, which I let sit out for like a week. I then took a sample of pollen biofilm type thing, and put it on a slide. The results were worth it. No clue what this little guy is, BUT, I know that like everything, slow mo makes it better. https://i.imgur....

Deliberate or not, that guy is chilling in a little protective house, even if it don't know it, cool thing to see. Plus, if its more stationary, it can be easier to play around with lighting and capturing it.

Re: Ciliate at high framerates(1400+ fps)
Very interesting! Thanks for sharing. So you’re getting these high frame rates by sampling only a small portion of the sensor for each frame? I’ll have to go back to your original post to try figure out what’s going on. Harry Yes, but it is slightly more complicated than just a smaller portion of t...

Only if the fancy strikes you, 'metachronal beat' of rotifer coronal cilia 'wheels' would be sweet with your high framerate application, so too would the waves of coordinated bands of cilia on many protozoa. Funny you should mention that, I did do rotifers a while back. https://www.youtube.com/watc...

Re: Various Spiral bacteria at high framerates(1400+)
Cropping does not increase frame rates. yes, its the roi set to 1488x76(100% of the horizonat resolution at bin2, and 1/20th of the vertical resolution at bin2) that increases the framerate, not the cropping of the horizontal distance. This is because of the way cameras are driven, speed through ve...

The quoted specs of your touptek camera say "Ultra-fine Color hardware Color Enginne ensuring high frame rates(Up to 15 frames for 20M Resolution);" 15 frames is a bit away from 1450 frames.

Re: Various Spiral bacteria at high framerates(1400+)
You are confusing exposure time with frame rate. No? The framerate means that roughly 1450 frames were captured every second, exposure time was about 60 microseconds by my recollection. I can't see a full image--just a small preview and no motion. Hmm, they are all relatively small (<20mb) gif file...
