Hi, not sure. When I converted the .MOV 4K to mp4 for YT with AVS I chose the YT option. Is it possible to put 4K onto YT though - the file is over 2GB for 5 mins...
Perhaps I could provide a link to download the 4K or even a smaller part of it for you to peruse in the full 4K straight from camera?

Hi Mike - what a coincidence! Only this afternoon I've been examining what I think is 'jelly lichen' - Collema.fasciculare found amongst some moss samples while peering through my stereo 'scope. I took a few images the other day, see below, and today had a go at crudely halving the 'round things' an...

Hi, it's a lot like darkfield patches - higher magnifications need larger center spots for the background.

Forgive my ignorance please, John ... but can you explain where the 4K claim comes from ? The back of the camera mentions 1080P and 2K , but not 4K MichaelG. Hi Michael, cripes! I see what you mean, the decal is wrong! This version has the 4K (i.e. 4000 pixels across in 4K video) capability at 25fp...

Hi all, here's another bit of stereo-microscope practice that may interest - the dissection of a moss capsule and the making of some water-mounted temporary slides for compound microscope images.... The capsules in a sample of garden mosses useful for practice. https://lh3.googleusercontent.com/pw/A...

Hi John, apparently the chinese printed all necessary information on the outside of the housing, perhaps there is a side with closer instructions? What I can see from the print on the housing is that it is powered by a V8 motor and at 4800W it consumes quite some energy, not for a V8 but for a came...

I understand why the CMO is better-suited to photography, but why for botany in particular? These specimens seem to have a lot of relief. Hi Bram', I find the CMO better for my use as I really do like the 'straight-down' (orthogonal?) parallel images pathways, which are in use virtually identical t...

Hi, no ToupView only seems to support it's own ToupCam branded cameras in my experience. The ToupView software is so good that it makes a ToupCam my first-choice C-mount camera for sure. This is seriously offset, to the extent of causing my search for alternatives, by the pathetic and virtually unus...

Cripes - it's gigantic! It looks as though it may be heated in some way?

Hi all. As the title of this post suggests, I recently bought a 'Chinese unbranded' C-mount camera at the 48mp still and 4K video rating. This is all part of my ongoing battle to achieve at least usable video records of my many and frequent Botanical dissections. These I make as part of my slide-mak...

Very nice, clear and sharp images - well done!

Very interesting indeed, may I ask what model 3D printer you used for this?

It's correct that phase contrast requires the 'normal' Kohler set-up, i.e. the same as brightfield without phase. In addition to this correct configuration of the condenser, the phase rings must be correctly aligned, a seperate and usually once-only task. If you can put the phase condenser under a s...

Hi, they're pretty cheap to buy and just about any one that fits your eyepiece-tube diameter will be fine. It's job is to allow you to focus on and inspect the back of an objective - which is where the alignment of the phase rings is seen. The telescopes are also focusable of course simply by use of...

Hi Don - I can't see what you mean I'm afraid, the images don't have anything I can really recognise.

Hi, I posted re a dirt-cheap way to fit a very bright LED panel under a stereoscope's stand a while back. I've been using this method for several years now, and have even transferred said panel to my newer stereo 'scope as it is so good.... See my post with images . This is a very good solution inde...

I have the same problem with my i7 Windows 10 HP with SSD laptop. It boots and loads Windows 10 in about 4 seconds - but runs Toupview with a 5mp Toupcam at a pathetic 2-3fps.... My 32bit Linx Windows 10 tablet doubles this.... Tried just about everything, power settings included, driver loads/reloa...

Hi Rossf, I used the 600 series condenser Apl 1.25 oil flip-top, https://lh3.googleusercontent.com/obFdh6oDJPiYYdlBFKtYg9es60EYnhNUioK0GLFk_JnS2wPe7KHJgKL9f2uQQQDRujGEFxc0VBRm4PK103Hey7aBaqmCReqGFKZAi_xaELFI5E7P3QpDtshq2y1dudd2nQ9fafFZ8nmr5coG3xvKUEu_up6NvcDt8yxMXWXfdZDWez2s2sLI63mEhl7fKcMZ_-LJBiWl1...

I didn't have that problem but it's definitely worth checking. Rest-assured though that the seller listing is honest and would I'm sure refund you if you had any problems. The 100X apo that I had was a really bright & clear objective, a real performer. There's no harm in asking for a final check - a...

Hi Rossf - here's one of the 100X listed now in the U.K.. The seller is one from whom I've bought several times and is totally honest and reliable in my experience. Very likely responsive to an offer too. I've no connection whatsoever with this seller beyond my custom of course.

Here's a link to an explanatory (internal) Leitz memo at the time of Leitz adoption of the std 160mm TL....

They really were superb.
You need to ensure that your TL is correct for your 'scope - there are 160mm and 170mm (Ala Orthoplan in the above case) 'scopes and objectives.

Thank you very much Mrsonchus for your very helpful and very detailed reply! The "Water immersion", in terms of time and "feasibility", in a very good compromise. Unfortunately, I'm not able to view your images, but I'm beginning to hunt the two W Leitz (especially the W50 1.00) Thansk again. Toni ...

Thank you very much BMN, I will try to follow your advice. In the old Leitz catalog there are many "oil" lenses, even of medium power ... Ther is also some Water objective (W engraved)...they are said to be easier to use, but equally good even if water has smaller refractive index than oil...and pe...

Hi, I recently acquired a Nikon SMZ800 my first job was also to attempt to attach a camera.... The top of the SMZ's photoport is the target connector! https://lh3.googleusercontent.com/pw/ACtC-3eUwRq156brLD0MSRMKItAVKzAsP5WGh2tR-Hy1xM-yfyuQH4xXxvO10n7IKpWo1DR6CMc8zYrecsNymK94l7-QVQZgSfEN0VgFF89Aq3KO...

Hi Bob - yes, not only do such 'infections' make good images, they're pretty easy to achieve also. The penultimate image is safranin + alcian-blue (an alternative to safranin + fast-green). I prefer fast-green for accuracy and subtlety of finest detail but alcian-blue for more 'drama' in vivid colou...

Great idea for an interesting thread - enjoying the mysteries.

Hi, this was in the tissue - a typically 'mushy-brown' appearance of an infected closed-vegetative bud. It's a handy stain and very cheap. I also have sets of slides that I have made of infected plant tissue, e.g. Sonchus.arvensis stem and leaf tissue. The permanently-mounted slides are great as I a...

Hi, I use pre-made lactophenol cotton-blue for live staining fungus - high contrast and pretty good.
Here's an image of some fungus which as far as I can remember came from a rotting plant bud. Water-mounted with coverslip and stained with LP stain....

I ordered the same eBay set a few months ago for my Olympus SZ, it took some time to arrive, pretty pleased with them.

Would it be possible to post an image of them? They sound interesting...
