Amoebae phagocytosis

Hi folks, I've learnt a new fancy new word today. Hope I'm using it in the correct way. Anyway, I was playing around with a small drop of water from a water trough yesterday when I got these images. I think the food is a paramecium ? I've been trying to get some images of these speedsters for ages. ...

Re: Freshwater Pond Critter

Thanks Bruce, That's a whole bundle of mysteries solved :) I hadn't heard of chytrid sporangium. But a read of wiki and a google image search has provided answers to many questions. I had thought the "round brown things" were some sort of parasite. Here's the wiki article for those interested. https...

Re: Freshwater Pond Critter

Interesting thought Bruce. I know what they are in a terrestrial sense but hadn't thought of them as aquatic. A quick google doesn't turn up much but will have a better look later. I also spy that the first image seems to have gone missing from this post, no biggie, it didn't have any detail to it. ...

Freshwater Pond Critter

Hi Folks, Can anyone point me in the right direction for an id of these critters ? They look like an embryo to me. They're attached to the algae by a triangular tether. Approximately 30 - 40 microns. There's nothing in the water sample that is big enough to lay these, plenty of rotifers a few vortic...

Hi Hobbyst46, They are cut from their original background in Photoshop and the background replaced. CA and other fringing etc sort of fixed. Lepocinclis is a stack. All critters alive in an "aquarium" I made on a slide. Mounting diatoms or anything this small is well beyond my skill set. I'm in awe ...

Yes the price is really reasonable, especially when compared to ebay prices. But this is a working microscope,...

Hi folks, 75RR, Yes I tested it with the wide field Chinese eyepieces that I have.

Finding a pair of Wild wide field eyepieces in NZ, wo...

Well finally got the 10x for a trial. Unfortunately, it's no hidden gem :( By comparison with my Chinese acro the ca was worse. It definitely was not flat, way worse than the acro. It also had a yellow tinge to the image, of course easy to fix photographically but my eyes never adjusted to it. The r...

Chaetogaster Diaphanus

Hi folks,
This critter came out of the debris from the bottom of a water trough.
It appeared to graze on the pieces of algae as it swam around.
It was possibly 5mm long.
Head is to the right.
Thanks

Re: Wild Plan Fluotar

Michael,
Thanks for that lovely catalogue, classic 60's and nicely scanned.
Full of great info as well.
Based on the descriptions of the eyepieces etc it seems that they are flat and corrected.
Will grab the 10x and see how that goes.

Hi folks, Does anyone remember these objectives and how they performed ? I'm guessing they have to be 40yrs old ? I've found 3 a 3X/0.1, 10X/0.25, 40X/0.65 and figure they would go well with my M20. Like most of the objectives I see I can find very little to nothing about them. Did these require a m...

Hi folks, These are growing on the inside of one of my freshwater jars. They are only a few mm long and expand and contract on stalks with a holdfast on the jars surface.
