Thank you, much to learn still, I was thinking more along the lines of schizogony merogony or endodyogeny, but can see now that it's reserve for only parasitic protozoan?

Did you happen to catch the other video I posted?, not sure if it was cytokinesis now.

Thank you Bruce

Two Hypotrich doing it

First time playing with the new camera from Aliexpress, was able to only take still pictures since the USB is not 2.0

Im very happy to hear that,How powerful is it normally on epi illumination? haven't gotten to start experimenting with mine yet, had to deal with the "mold problem" I had been considering purchasing a Cas 200 system for my Microstar but instead Im going to tinker with the DIY tube. I have been ponde...

I've been obserbing this rotifer for a while now, its the same from previous videos, I started to notice the formation of the single cell organism within the its carcass but cannot find a match. Bacterial growth can also be seen around the carcass.Anyone has ever seen this or can point me towards wh...

Very nice Don, how do you get such of nice 3D effect?

Formation of hyphae 12hrs later along with a substantial amount of bacillius bacterial growth can be observed.

I believe you are correct, it looks like Arcella conica or Arcella megastoma,

I need help verifying my findings and possible species, input is appreciated What better way to spend thanksgiving 2020 than to deal with a mold issue. A little back story first: After procrastinating for week, I finally decided to change one of my upstairs bathroom floor, much to my surprise I foun...

Just ordered a pair, can't wait.
Thank you.

Is this an algae?

This morning I went to check the slide I had prepared last night, in which I saw a Notommata viogti, a colossus among Rotifers ( https://youtu.be/HJAbRq2OdoE ) . This one had a giant egg inside of it and so I was hoping to see if it was still there. Much to my surprise I found the decomposing Notomm...

Here's a video of what might be Notommata voigti...not sure

Thank you Greg that is going to help a lot, will keep you informed on this thread of the progress, I plan on using a laser on the rear light source and pass it through a bean splitter on the tube before the dichotic mirror......if you don't hear from me its because I bore a hole in my skull from the...

Another way to maintain slides is to.... Get a plastic Tupperware with a lid, put some towel paper on the bottom, get it soaked with water and then put two beer bottle caps ( brownie points if they are from some rare IPA) on top of the paper. On top of the beer bottle caps goes to slide, I wouldn't ...

Good morning Greg, can you share which mirror you ended up choosing for this section? I plan on following your advice and making it adjustable with a bolt, the question is how does this work is it just one mirror reflecting light back down to the specimen? Wouldn't that same mirror block the light c...

heading to the hardware store first light tomorrow

Okay thanks for the replies. Are kimtech wipes good for cleaning the oil off of objectives? I have personally seen the optics in my school deteriorate because of the use of kem wipes on them (or it could be just user error), opinions are mixed even on youtube instructional videos put out by microsc...

Thank you Greg.

Greg that is amazing and I thank you for sharing it, This will definitely be my next project, ok so the one inch mirror seats inside the tube below the head, and then there is a second mirror deflecting light back to the objective? also the difusser goes where.? Looking a sketch of epi illumination ...

I was able to rotate through all the objectives an maintain polarization.
I guess some samples don't reflect the light like others as in the case with that Stentor.
What do y'all think!

Something is wrong. White light is most likely passing the polarizer on the sides causing an oblique mess. Experience says close down the diaphragm any way no matter what the book says. The book is not you and does not have your equipment. So try that. Greg Hi Greg , close the condenser iris or kho...

Can you obtain extinction?

Yes, I think It was user error, I was lowering the condenser more than I should had.

It is very easy to accidentally swing one of the non oil objectives onto the residual oil on top of the slide cover by accident, so its best to clean it and set up another sample. The time spent in doing so is not comparable to the headache of a damaged objective. That being said I have used the non...

Yep, both are up, the effect can be graded by rotating the lower filter, and is very visible at lower magnifications but use the 40x and it starts to look like oblique mire than polarization which i don't understand, the manual calls for the condenser Iris to be fully open.

I started to play with the polarizing kit on my Microlux, and notice that at higher magnifications 20x and above the effect is not that noticeable is there a way to improve the polarization effect? Does the condenser need to be as far up as possible what about the iris diaphragm? I keep getting mixe...

Thank you for that Greg, would love to see if you have pictures of the set up. I also wonder if they can be used in conjunction with the polarizing filters to clear the image at higher magnifications. I know I got plenty of room on the Microstar but not on the Microlux to set up some sort of upper i...

When comparing the color temperature of the light on my Microstar IV vs the Microlux IV I noticed that im able to swing in the blue filter that is housed inside the Microstar, which makes it a lot easier on the eyes. The Microlux on the other hand has no blue filter, there is a polarizing filter bel...
