Many thanks Lomonaut, glad you liked it.

. Many thanks Wes and tlansing I am curious how you captured the images to stack them. Individual photos, my Zeiss Standard WL has 2µm graduation on the fine focus and one can halve that if one is careful. I basically turn the knob as minimally as possible until I see a slight change of focus of the...

Nice catch and video!

Thanks Francisco

. Any of the finite Zeiss Standards but particularly the 18 and the WL (both come with removable nosepieces) are well worth having. One should not have a Phase Contrast System however without trying COL http://www.microscopy-uk.org.uk/mag/artdec02/pjcol.html https://www.microscopy-uk.org.uk/mag/artn...

Thanks for the ideas guys. I know there's a bunch of granite/marble places by my work so maybe I'll loiter around to see if I can get filch a nice scrap slab. I spent a long time (months) peering into skips hoping to find a suitable slab of marble. When I finally did find something that looked prom...

BTW, typical forward LED voltages are ~3V AFAIK, so for 10W the current should be ~3A. For clarity … mine was a COB LED , with multiple LED sources in a common matrix Rated at 9 to 11 Volts Similar to the one shown in this listing: https://www.ebay.co.uk/itm/154451507928 MichaelG. Like the features...

. A 10W LED produces a lot of heat. That is not something you want inside your microscope. An incorrectly installed high Watt LED light might not cook your sample - but it could well cook your microscope.

This is what the Zeiss 'The Clean Microscope' booklet (see page 10) has to say:

But nor do I really like having to monitor and refill calcium chloride flakes! Was reading up on homemade dehumidifier boxes and someone said they channeled the heat from their UPS (which is always on) into the box. Might be worth looking into especially if you have a way to measure internal and ex...

Nice, and as you say, distinctive!

There are two refillable calcium chloride damprid canisters inside to keep it dry (I'm in the tropics). I cut out small grooves at the bottom of the back of the box to let the wires through. I have since lined the whole box with plastic sheeting on the outside to make it less breathable so the damp...

They are not very abundant but with patience you can find these orthosiras https://live.staticflickr.com/65535/51586531887_b4ab3bbd07_b.jpg https://live.staticflickr.com/65535/51587588573_fbd2798b75_b.jpg https://live.staticflickr.com/65535/51588269515_a0eb5d3c8f_b.jpg . These are quite simply amaz...

Dunno - grey area? I suppose, like any motile organisms, they move away from potential bad things but towards things they sense as beneficial. I don't know how many diatom species can actually move - only some? See link below for degree of Motility https://diatoms.org/species/motility/non-motile .

I enjoy my microscopes but I'm not into vintage scopes because they are just not readily available on this side of the pond, so I stick to Amscope.

Thought you were in Oregon USA. Are you elsewhere?

.
Nice work - you might want to try a green filter with the camera set to mono - see how that turns out.

I didnt check much as I disabled the stabilization but I saw on a Panasonic camera you can also configure or give a directional hint for the stabilization, eg movement is only horizontal. That function is for panning (following with your handheld camera action that takes place across your field of ...

Looks like you are having plenty of fun playing with your monitor arm. Look forward to your results.

Did you refresh yourself with the contents of the force applicator when you finished?

Great image of a radiolaria

Our group has a SEM, an old Leitz 1600 from about 1970. Here you can find images that were made with it:

That is pretty cool. What are the maintenance/running costs like?

.
Great catch and video!

The article reminds me of a question I have on shutter shock: To what extent will the in-body image stabilization offered in some of the newer cameras help with this? Since in-body image stabilization works by moving the sensor to compensate for camera shake, unless I'm missing something, it seems ...

Have a look at these two links - should sort you out

Make sure you look at the photos on krebsmicro, they are a treat. As to the articles, they are invaluable .

. You are probably right about the cost and weight of a glass dome large enough for a BX50, I have seen a more modest sized Zeiss GFL in one though. Agree acrylic would be more practical. Would be nice to be able to see one's microscope when 'covered', though there is the extra space to consider ver...

They used to cover microscopes with glass domes - might be worth looking into

Nice and colourful. Hand Microtome?

Could you explain what you mean by:

"I have uploaded screenshots to reduce the size as on my phone."

Very fine images. Thanks for sharing them

Nicely detailed, also liked the pointers

Thanks :) I did center the ring. Since I didn't have a tower, I held a 15x over my eye piece. I could see the annulus and ring pretty well. What are the hints on the video that the annulus is not well centered? Phase, like all the illumination techniques requires careful setting up - from the amoun...
