Thanks for the ID and the link. There a few of those in some permanent slides I made of the surface film of a hay infusion. That's got me thinking... I have a big rotten pile of hay in the back yard, where would be the best place to take a sample and how would I prepare it? Should I for example tak...

2x is overkill - well into empty magnification territory. It rarely provides a better image, not sure quite why it was included. Will have to check at some point if the Optovar has an effect. By which I meant I will have to check that the 1x is indeed 1x Here is a link to a pdf on the Optovar: http...

Should work fine... You may need to vertically adjust the condenser a little to fine tune the darkfield stops. Make sure your filter holder accepts 32mm filters yes it's 32mm at the top, 30 at the bottom, I checked it with the digital vernier. You might first try with a homemade one... Not all cond...

Will have to check at some point if the Optovar has an effect. I imagine it would, it would be just like using an objective of higher power would it not? I have a similar system in the optical train on my IMT-2, it has a factor of 1.5x Is that how people achieve magnifications of 2000x, with system...

Here is a link that describes it well: http://microscope-microscope.org/advanced/reticles.htm Thanks 75. I read it through and it's basically the same process I used, which was nice conformation as now I don't have to wait until you guys on the other side of the world wake up tomorrow to verify my ...

to provide 'accurate linear measurement' your eyepiece scale now needs to be calibrated, for each of your objectives, against a known reference. That's right, but it never hurts to state the obvious Michael. Fortunately I have a calibration slide that I used to fix the fov of my 10x and 40x objecti...

Has anyone had any experience with these? The go in my filter ring below the condenser. Any reason not to buy them and experiment? http://i.ebayimg.com/00/s/MTYwMFgxNjAw/z/3YkAAOSw5cNYhtge/$_1.JPG ebay link https://tinyurl.com/ybsfnqm6 There are other variants. Here is the full range https://tinyurl...

Well beyond me, I'm just a black box operator at this stage but keep us posted on what comes out of the EP. I found a DIC kit for my olympus imt-2 going for a grand and a half (they are generally 6 grand) but it was an Indonesian company that accepts only wire transfers or cash, no CC or paypal so I...

Maybe it is not parfocal with your other eyepieces. This could be corrected by lifting one of the eyepieces with the correction helix. It arrived today and looks new. The top lens is wider than mine, the image brighter, but it's a perfect fit and parfocal with mine. Even sits at the same height rel...

Thanks bill. I'll study it before I proceed.

Make sure to check any doublets near the bottom very carefully for oil invasion.... There are none, it's an old scope and all lenses thankfully are single elements. I have done dozens of these and it is amazing how much dirt or film can cling to those lenses, quite unperceived by good eyesight or e...

download the 3 volumes (you might need to brush up on your german)

that's what google translate is for thanks

Great. thanks, downloading now.

This one is about 80u long, swam in a circle and whenever it brushed another, even much smaller protist, it recoiled very smartly. I looked in my resources and bing images but I'm stumped. The closest I came to something similar was Epenardia Here is what I have https://s6.postimg.org/6rg2v4v35/UNKN...

Thanks 75, another one for the archive. Just in case

Welcome desert rat, I am down in Australia, in the capital of Brisbane surrounded by lights of all kinds but the moon and the planets are best observed under such conditions, because of the better contrast. Though I must admit, looking through a microscope is a lot easier, especially as one ages.

Hi, Thanks for sharing this interesting disassembly... Could you tell how the phase ring is put on the element.. Is it painted on?.. BillT I didn't notice to be honest, I lost my loupe a while ago and used only eye glasses so could not see any great detail. I have a few ordered so when one arrives ...

Thanks for all the input guys, I decided to strip it down and as it turned out it was immersion oil caught between the bottom 2 elements. I cleaned them up with isopropyl alcohol and the empty objective barrel with petrol then isopropyl. I assembled it all by the numbers (But I think) the second bot...

I think if I pitch it to the wife as a "water feature" for the front yard butterfly garden I might have a chance. ;) CE She'll see straight through that. Say your going to breed gold fish as a passive income stream :) You have motivated me to go out and search for some more weed for my little tank....

Hi again, I compliment you on being eager to explore protozoa...when you mention: 'parasitic protozoa'...well you already have expanded your understanding of relations of protozoa to the totality of our world. Aside from a basic uni biology text, the parasitic protozoa is the only paper book I have...

I bought an old Nikon lk-e with phase contrast on the cheap off ebay and the 10x obj has this defect. I guess it's a bin job right? All else on the scope is good.

A lovely rambling thread of your spring exploits Charlie, I didn't know this was down here and will pop back when I don't have to go out the door to work. I love that black cat in the first pic, closest to the fire, they're not stupid.

Welcome, look forward to reading some of your posts. What is your main area of interest?

Yes good clip, so much detail in the slow mo

Hi, coominya, great to see your enjoying freshwater communities Charlie guevara Thanks Charlie, that's a very detailed resume of various methods of keeping the organisms alive and well here at home. I think I will begin with a light over the small tank, to give it some daytime, as at present it sit...

Great capture Rex, which of those microscopes did you take this one on, the Standard RA.

She's a pushy fellow that water bear. good video.

That's a fine instrument piilani2000, I use one of about the same vintage and love the precision of the controls and optics. Pop down to the Beginner's corner if you have any questions regarding usage, there are a lot of experts on the field residing here that are only too happy to help.

I don't know much about Olympus gear, may be the new eyepiece fits perfectly to your objectives, at least it seems to be of similar age. Maybe it is not parfocal with your other eyepieces. This could be corrected by lifting one of the eyepieces with the correction helix. That's ok, I don't mind a f...

You would have to try how well the chinese eyepiece fit to your objectives optically. On rethinking I decided chinese made was not for me, I don't have any faith in their gear. I bought this instead, it was local and cheaper. Will get delivered in a week https://s6.postimg.org/kyhvkclup/image.jpg h...
