Great, thanks. I just might try this sometime. To meet one of the tenants in person...

Hm, is this AI powered spam? It would be interesting to see the Internet inhabited with AI only without us... Let them talk to each other and see what happens :D Who knows maybe we already have a trusted AI member here. Maybe I'm the one, or who knows :mrgreen: Anyway I suppose an AI inhabited Inter...

If you can recommend any LED with a suitable electronics, I will be very grateful to know :) This is what I did, look at the last post for the latest version. Dimmer works great. Higher voltage doesn't mean higher temperatures, higher power (watts) mean more temperature... You can limit the upper v...

Mouser has all kinds of Cree leds. I made my dimmer with a step down converter from Ali express it worked without any flicker with any led connected. Including cree. And cheap maybe 5$ Good thing is that you can limit max voltage and use any Power supply (e.g. 19V 3A old laptop adapter (free) to pow...

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

I'm glad you like it...
We recorded this in 1080p, decided to prioritise frame rate (50) over resolution. As my camera can't do 4K in 50p

Thanks for sharing your expedition.

"Clear Creek Plankton Drag" might be a tune the Band feat. Django Reinhardt somewhere in the parallel universe in the 70s

I have a 25 and it isn't delaminated... I know nothing more of it

I'm selling an Olympus SZ40 in good condition, has some dust inside, I won't clean that as I don't think it affects performance. The stand has been completely cleaned and lubricated, so it is perfect now. Eyepieces are new, but not original: WF10X/23 focusing. images: https://ibb.co/album/HLJ2WR inf...

I just recieved WF10X/23 (focusable black version) and they are almost parfocal. Just a little less parfocal than the genuine Olympus GSWF10X/22 (which are almost parfocal too).

Definitely usable without much hassle, I didn't notice any difference in image quality...

I'm interested in el - nikkor 50mm, just don't know which one I'll pm you

Yes, you can charge and use at the same time which is great, no need for dummy batteries. And the completely electronic shutter is a nice feature, for concerts or when shooting people, they act differently when there is no sound :D . For photomicrography it might be useful only if you want to do bur...

Thanks, I'm glad you like it... Biggest con is that it crops 100 frame video quite a lot, 2x or something. Micro video is great, I didn't do photomicrography much, but for general photography I enjoy using it, I feel 12mp is enough for my stills, low light performance is great and the camera can be ...

I think you can't, YT suggests different videos for each user. So it has nothing to do with your video, but YT algorithm...

When you get the stage and the condenser back, I think you might be having everything already...
Just find a way to attach a camera and enjoy

I have a similar one, I think one model newer, from 1920s with fine focus knobs on the sides. It does get some use occasionally, I love the looks and the mechanism.

I suggest you see a doctor I don't think it is possible to really evaluate water without proper lab equipment, a specially equipped microscope and knowledge of the lab process. I think you'd at least need a centrifuge and some contrast method other than brightfield. Although you can look at it for f...

Would you recommend buying some 160 din chinese plan objectives for the BH2? Here are some of the pictures that I took with my DSLR. https://imgur.com/a/xhE6y6m If the ones you have work with your microscope, I think you're better off using these while waiting to get Splans or Dplans for BH-2, they...

A short journey into one of my favorite fruits. Raspberries are beautiful under the microscope.

Nice, a bit of an 80s feel with the music...

The problem with Zeiss/Jena and even Reicherts is that they're absolutely ridiculously overpriced in Austria and Germany alike and 99.9% of all listings are called "stereo-microscope" but are just binocular compounds. The few actual stereos I've found are totally trashed :-/ I couldn't find AP Ster...

Hi, I have a spare Olympus SZ40 I want to sell, price would be within your budget, it is in nice condition. Pm me for details, I'm in Croatia...

My first try with the heat gun helped a lot, but coarse focus was still stiffer than I like. Today I removed the stage, which gave me some access to the inside of the focus block. Not complete access, but enough for mineral spirits to wick inside. I put a knapkin under the area to catch any mineral...

Thanks for the detailed info

I ordered the thing it should be good...

Seller seems to know something about microscopes and claims there are no problems, apart from the missing eyepieces.

There are a lot of these achroplan or a-plan objectives listed on ebay for ridiculous prices. Nobody buys this. If on auction they sell for 50 or close... I just sold one achroplan 10x for 40€. So wait a bit and 20x will appear...

While the nfk eyepiece works OK with the sz40 you can also just direct project onto aps-c with imo better results. Now you got me thinking... Although this purchase should be a good chance for me, as I might break even in the end. I started thinking if it will make the whole microscope a lot bulkie...

I've had good luck with them, especially the ones with a diopter adjustment. In some stereo scopes (Leica CMO, Olympus SZH-U, etc.)they need to sit lower in the tube to be parfocal. The price is right, even if you later decide to go for OEM eyepieces. My own SZ40 has Olympus 10x/23 eyepieces. I men...

Hi, I found a SZ40 trinocular in Europe, the first one in a year or so, it even has a SZ-ILA base and most importantly price isn't over the top, not a bargain, but ok. Missing are the eyepieces, NFK photo eyepieces, collector lens for the base and the photomicro L adapter (SZ-PT and the one below ar...

You can find a Dplan 40 for less, just wait a bit. I bought mine (10x) for maybe 30$. Here is one sold a few days ago: https://www.ebay.com/itm/304823197151?hash=item46f8e0dddf%3Ag%3AHe0AAOSwULJj~7bs&amdata=enc%3AAQAHAAAA4CULQ9Z7vtw4kGYWN75bk214Bizlve4QQjvp3Q5Ffh%2FqY1C%2FGcqEMrfFo8TSMt65EI%2B8%2BjU...

OK, sorry PeteM. I was a bit hasty and didn't realise you said it all already.
Anyway dtrinh good luck with finding a trino head, it isn't easy to find a good one with a good price tag.

I had a similar g4 led to yours and it was declared as non dimmable, but I could easily dim it with a step down converter. I bought it locally. The other one I tried to dim the same way would start flickering instead of dimming. So best to try out, step down converters can be found cheap (few $) fro...
