Paint

Hi folks, I'm looking for a memory refresh. A couple of months ago someone on here came up with a name for a crackle / bubble finish paint. It came up as part of a thread not a thread in itself. Sounded just what I want. When I looked it up I found it was available in my country, surprise. I'm prett...

Re: A O Spenser 25X eyepieces

Thanks apochronaut
Thats useful info.
Yes they are the 186
Good to know they are decent optically.
Like you I doubt they will be used often, but if I can pick them up at the right price they will be useful to have around.
I thought I had Spencer spelt wrong :(

Does anyone have any experience with these eyepieces?

Araphid Diatom

From a freshwater wetland pond.
Around 13 microns horn to horn.
Quite neat watching it slide along, it moved in a curve rather than a straight line.

Re: Size Elodea cel

Looks good. I found a couple of images on the net with field width stated then divided the number of cells into it, rough calculation. Both gave me around 75 - 80 micron length, 25 width. Guess it depends on which of the species you have under the scope as well. Then I found this https://plato.acadi...

Metopus ??

Hi folks,
This one has been bugging me for a few days.
Metopus is my best guess so far.
Free swimming and constantly spiralling, cilli appearing to rotate around the "mouth"
In a freshwater wetland pond sample.

Paramecium caudatum conjugation

Hi folks,
Saw a few paramecia doing this the other day in one of my water samples.
I'm fairly sure as to the id of these but happy to be told otherwise.

Re: Wetland Cillates

Hobbyst46,
Thanks for the maths :)
I can understand that.
The "aquariums" I use are .2 mm high
Now with a big drop of water I can get .1
I'm now wondering if I have created problems for myself by using aquariums.
I do like free swimming critters.
Cheers for more things to think about :)

Re: Wetland Cillates

What you say has just made me think.
So does a larger drop of water create a larger space between the slide and the coverslip?
Within reason.

Re: Wetland Cillates

Thanks hkv,
Yes I suspect you are right about the stress on the first one, it wasn't moving.
The holes were constantly changing size and moving.
All the others on the sample were swimming freely.
It makes me wonder how thin they must be to be able to swim freely between a slide and coverslip.

I'm going to concur with Kurt on this. Informative thread. As per for me it shows I've been doing things wrong, nothing unusual. I'm slowly building a frankenstein fotoscope.

Freshwater Fingerprint

Hi folks,
Another from the not sure department.
Have found 3 of these over the last couple of weeks.
All have come from 2 separate freshwater troughs.
They have been used by cattle, sheep and a variety of birds over the years.
My thought is Lepocinclis.
Thanks for any thoughts.

A versatile unit.

It appears as though the scope only goes up to 31x rather than the 40x of the JM

Olympus Stereozoom Model

Hi folks,
This microscope is for sale in my part of the world.
I can't work out the model.
It's not often google lets me down but this is one of them.
Any ideas ?
I guess being Olympus as long as the controls and optics are fine it should be a decent scope.
