Zeiss lens spray is relatively inexpensive and about the most effective.
I don't have shares in Zeiss.

For some added fun polarising is relatively straightforward and not expensive.

I found it as AO orthoro illuminator in the AO information.
Double checked.
Science -net PDF.
Might just be the same pages anyway.

I found a bucket load for the orthoro illuminator, is this the same thing?

Welcome aboard from the Jurassic coast.
I wish I'd been shown diatoms and Radiolarians in DF at school.

Top results.
Good luck with finding things to put Infront of it.

Diatoms in DF should be enough to hook anyone. As an horologist my collection started with an original model Mantis, used for things like overcoil balance springs,great for PCB work which is it's intended application. Fitted an old binocular type USSR 8.75x to the lathe for pivots mostly. It went wr...

Very nice DIC.
Bit spendy but hard to equal.

The light is refracted in the silica in the same way as a prism of clear glass.
Polarising helps with clarity, rainbow pictures are much more colourful with a polariser,rotate until the colours are strongest.

Anything but WD40.
I have whittled WD40 down to cutting fluid for tungsten micro drills and the party trick of bursting balloons in seconds without touching them.

Sorry, I only copied the title.
It's what you linked to.
Works on thread fungus better than anything else I tried.
Now my first choice go to for coated.
Only tried on Nikon,Watson,Euromex,GTvision,
Canon, Panasonic and Pentax

https://www.ebay.co.uk/itm/3344959 Yes, I have the other suggested solvents also. For removing fungus I have found the Ziess cleaner the most effective. Not saying it's not good to use whatever works for whatever residue. Internal fungus can come back if it's not neutralised. Kill it all, it's bette...

Love for life is the best life support there is.
Every day is a gift.

Good luck with your latest project. The BX should give better results than the Watson when finished. I'm very biased to Watson. I have other more recent scopes also. The Microsystem 70 is enough to hook anyone into the world of microscopy. Microsystem 70 optics in fully restored condition are still ...

Take it up with the industry.
Probably best to keep it separate from Kohler.
Personally I have no problem with DF.

Says turret condenser na 0.9 which I took as Zernike dry.

What is a " Zernike dry" condenser?

Really?
It's not oil at 0.9na unless you really like oil.
If it has a turret with choices I'm trying to picture something that isn't Zernike.
Either way it's Zeiss not AO.

Says turret condenser na 0.9 which I took as Zernike dry. .75 would make sense as the DF limit. Any gap between the condenser and the slide with reduce the effectiveness. Anyone who focuses for BF Kohler and switches to DF is welcome to do that. It doesn't work, and it's pointless but each to their ...

Is the top lens of the condenser in contact or near as can be with the slide? Is the condenser perfectly centred. My experience differs slightly. 0.9n/a is a dry condenser. Relatively low n/a, it is possible that under perfect conditions that DF is achievable at n/a .75 or less. With an air gap/focu...

Always get to the camel train first.
Wouldn't want to get stuck with an ugly one.

Although we look out into the vastness of the universe and marvel at how small we are, we're actually huge. Scale is such an interesting concept. There's a fella who scaled up the Idea of taking a rechargeable battery cell and packing them by the thousands into vehicles. It should keep third world c...

Works well.
Have you tried polarising?
Polarised DF also.
It's all good.

Children grow up afraid of the dark.
As adults they become afraid of the light.
Plato,or words to that effect.
Fear of the unknown.
Intolerance to uncertainty is linked to the fear of change.
Change is a certainty so it's not a logical loop maybe.
Take care.

The subjects are excellent.
Images look cropped?
Good luck with 20x.

Excellent results, very clean samples.
What NA/DF are you up to with the inverted?

The Nikon Labophot 2 filter pack also has a diffuser.
Both are acrylic.
The fly eye gives images a kind of sparkle effect from generating multiple light source points, what is probably described as "pop" in digital terms.

Are you using 160mm objectives?

It's possible the one in the bottom is only a filter.
If I remember correctly,
I had to turn the outer tube down to just below the hole for the thumbscrew to get full frame with NDPL2 in the tube.
The outer tube is only held on with the 3 little grub screws.

Excellent.

Panasonic Lumix G3 works well enough, it's only 1080 video. Metal body. Canon 50D has live view, solid metal. Doesn't easily do clean video out. NDPL2 is relatively cheap but I only have experience of type F trinocular. Both cameras are easy to find at bargain basement prices for what they are. Wort...

Interested to find out how things work out on a Labophot 2.
Only tried 30mm tube eyepieces with ∞ objectives.
Stand corrected on the 23mm tube eyepieces, should have reread the OP.
Good luck with the project if you take it on.
