Re: Advice about possible Bh2 purchase please

The only thing I can think of for a microscope that cost pennies are slides and cover slips :roll: . Everything else costs $$ :shock: . The good thing is, properly taken care of, a good microscope will last the rest of your life and then some. You will need an extension/camera adapter tube with ANY ...

Re: Advice about possible Bh2 purchase please

Ask the merchant if he'll swap out the infinity objectives for a set of DPlans. Pick up the right NFK projection lens for the trinoc and you're on your way. If he won't, and the price is nice enough, buy it, sell the infinity lenses for whatever you can get, and replace them with DPlans (or Splans i...

Re: easyzzom test

VERY nice! :D The annotations work very well, too.
It looks I need to do a bit of home work to see if this is better than Zoomify. I'm mostly interested in a stand alone solution.

Any comments Oliver?

Re: More microscopy outreach

Thanks everyone! If you can get to them when they're young enough, you can twist them pretty much any way you like. 8-) I've often thought the instrument manufacturers should do something like this, but on a much larger scale. The cost would be relatively trivial compared to the number of kids you c...

More microscopy outreach

On October 29th, I had my microscopes set up at a Science Fair Expo at the Riverside (CA) County Office of Education. Lots of displays and workshops for the kids wanting to do science fair projects. Many STEM experts, generally college professors, available for consultation with the students. Some 3...

Re: investigated 2 places for microbes

Very nasty indeed.

The CSF finding was a big surprise, but not as much as the patient's survival. If I recall correctly, that was the very first survivor. So just like finding a massive number of malignant cells in CSF, pleural or peritoneal fluid, you're looking at a dead man walking.

Re: investigated 2 places for microbes

Different amoeba, different target, different symptoms. Only just ugly, one almost always fatal. Entamoeba histolytica, GI symptoms usually, ugly diarrhea and sometimes organ (liver, etc,) abscesses. Abscesses may be fatal if untreated. Diarrhea ugly but most often self-limiting. Possibly fatal from...

It is fun, and you're right about their expressions. I love the photos. When some of them come around the corner to exclamations of "Oh, microscopes!" you know you've got something good going. :D

zzffnn, The main interest in the forams and diatoms were "what are they" since they really had never seen anything like that. The louse slide probably got more good photos, and actually scared a couple kids since it completely filled the frame. 8-) There are a couple of problems letting them move th...

And now we have a whole bunch of new photomicrographers!! Not too bad for less than 30 seconds :shock: of instruction.

Re: Throat cells, help identify organism

CmchPt, What apochronaut said, and: Your photos aren't useful for diagnosis. The mouth and throat contain so many different organisms that are normal flora that a culture is the only way to tell what is there that might be pathogenic, be it bacterial, viral, fungal, or whatever. Any worries about ma...

Damselfly nymph video

This video is a bit different from most. This is from an algae mat, collected using my plankton net from a slow moving stream. Not being an entomologist I was pretty clueless as to what kind of nymph it was, but was fascinated watching it crawl around in the Spirogyra. I decided that to ID it I woul...

Re: microscope buying question

einman is right. The Olympus BH-2 series are very, very nice microscopes. The very common DPlans are great objectives. BH-2's are very sturdy as well. Lots of parts available. I have several I use in outreach. I bought those as I had used them in a clinical lab for 20+ years and found them almost bu...

That's a BX series adapter that works fine with the BH series.

Re: Camera Vs Eyepiece

It's very likely normal, and it's not the condenser. Look at the camera live view output resolution. It's probably much less than the sensor is actually delivering to the file, particularly in older cameras. Even the sensor cannot deliver what your eye can see unless you are dealing with wavelengths...
