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?

Re: Staining lichen
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...

Re: Rheinberg illumination at higher powers
Hi, it's a lot like darkfield patches - higher magnifications need larger center spots for the background.

Re: Chineses Unbranded 48mp C-mount Industrial HDMI Camera
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!

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....

Re: Chineses Unbranded 48mp C-mount Industrial HDMI Camera
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, 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.

Chinese Unbranded 48mp C-mount Industrial HDMI Camera
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...

Re: PH alignment without a CT
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...

Re: PH alignment without a CT
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 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.

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.
