Re: Counting chambers
Sorry, slightly different topic he was asking about. No, it doesnt change working distance. Slightly changes magnification but its not noticable, other than that it doesnt change anything. (Parfocal extenders)

The eyes were clear on one frame of the video, it does have some on its rostrum, like a rotaria would.

Maybe one of those would help? I bought one from that seller, it was metal, arrived fast, worked perfect.

Video is working fine. :) In order for me to identify her I need to see her beak (mastax and trophi) which is halfway down her throat, looks like a diatom, and is often moving.

Re: Paramecium death
Distilled water is worse. It causes excessive osmotic pressure which is fatal. Thats why we use blood plasma instead of distilled water for transfusions and saline solutions for an IV. If you let the water sit uncovered for 24 hours the chlorine will evaporate off. (Boiling the water does the same t...

I am experimenting with xanthum gum, which is a polysaccharide produced by bacteria, aka a biofilm. I mix it to 1% with chlorine free water to make an odd light gray syrup. Then I mix 1 drop of that with one drop pond water. It slows them right down, but it takes a bit to thicken. It has the propert...

Oliver posted a new video with an odd jumping ciliate and a couple of square chloroplast containing phyllopharyngia looking things he needed help identifying. Can anyone take a look?

Re: Help identifying another old AO Spencer scope
I was sure that UC 1350 was a red herring, it didnt belong there. I was relieved to see I was right. I was somewhat sure it was a series 2, I had found the part number for the base, but I wasnt able to confirm the year of it and I didnt know if it was 160mm or infinity because of that. Apo knows, th...

Re: Swift SW380T or OMAX model (B005TJ5CEG)
If one gets a 185 and should have gotten a 195 then a $10 (ebay) 10mm parfocal extender can be used and works perfectly. There are also JIS (japanese standard) objectives made for a 170mm tube instead of a 160mm tube. If one gets one of these by mistake it will work but magnifies a bit more. Keep us...

Theres the starlight illuminator on it.
I think I know something about it, but I could not confirm it. I will leave it to apo, he probably has two of these on his shelf.

I like looking at live microbes, so for a regular wetmount I wouldnt normally use a toplight. For a no coverslip wet sample I may use the toplight to look at the top of bits of dirt or organic material for interesting fungal hyphae or maybe to look at a thick microarthropod.

The swift appears to have slots in the housing between the light source and its lens. My premiere has this and it allows me to slide in a homemade darkfield stop that gives me darkfield with my 40x and 60x objectives. (Not possible with filter rack homemade darkfield stops). The omax has a solid hou...

Re: Quick question...
Focusing at the eyepiece end instead of the objective end will cause a change in the scale of x and y, as z changes. I think this happens even when focusing normally, but if not then software could easily deal with this issue and only slightly degrade the images. It sounds like its not that hard and...
