Thanks Bill! I've been meaning to look up a source for those.
I just ordered a couple of them from you.

In addition to apochronaut's comments, mag changers also can be quite useful to aid in framing your photographs or videos in that they will allow you to more easily fill the sensor frame so you don't lose as much as when cropping in post. Particularly handy when shooting video as cropping in post is...

Some yeast in stool is normal. If you're sick and think you might have parasites :o , you might want to go to your physician and ask for a stool culture and Ova and Parasite Exam. Have a real clinical lab go through the proper bacterial culturing, O&P concentration and staining procedures. You proba...

He explains his technique in the comment section of another video: https://www.youtube.com/watch?v=7xvkEssi-Ss He doesn't use a patch stop, but de-centers the Abbe condenser, and sometimes uses a Raynox DCR-250 macro lens sitting on top of the illumination port. Oblique effect is obtained by condens...

Marty, The new price they quoted isn't that bad, and might be your best bet if you have a decent relationship with the vendor. I wouldn't go with an Amscope lens because you'll be mixing the Amscope objective optics with the Oly tube lens. Being physically interchangeable and optically interchangeab...

Marty,

Let me check my spares. I *think* I have one I could make you a deal on. Hopefully I can check tomorrow.

The glycerine, gelatin and formalin add up to 67%. I presume the other 33% is water?

Tom

Technicolor, Let the homework begin! I see you are in LA. I'm East in Redlands. Since it's really hard to figure out what you want to do without a bit (or more) of hands-on experience with some of the microscopes available, I thought you might like the opportunity to take a closeup look at some of t...

They can't. I expect an item to be as the Ebay description states. Ebay has very clear descriptions, and sellers are held to them. Used does NOT mean "as is" regardless of what the seller says. If they say "for parts or repair" then you're done. They can't sell crap as "used" and hide behind "as is"...

KB1FRO,

Definitely a Zetopan. Better yet, the Ph A (yellow band) objectives are Anoptral Phase Contrast . They're pretty rare, and should do quite nicely if you have a Zetopan phase condenser.

Q-tip moistened with 70% - 90% isopropanol (rubbing alcohol) works fine. Gently, with a circular motion, center to outer area. Don't reuse the Q-tips. Several passes, gently, if necessary to remove the oil and other junk. It usually takes me a half-dozen or so passes, fresh Q-tip each time, to get a...

PeteM, Way cool!! :o There's not enough of this kind of outreach!! I love it! I've done a bit, but the big shows are only a couple of days, once a year. Over 41,000 kids so far though since 2010. As you can probably tell, I like teaching the kids photomicrography with their cells phones, too. 8-) ht...

Kurt, Yes. Q-Tips and cotton balls from the grocery store or pharmacy, but gently. Pressure can drive any hardened debris into the soft optical glass of the lens and cause a scratch. I really dislike lens tissue. People tend to just stick it on their finger and rub it flat on the objective lens, usu...

Amoeba, I did also come across this: http://www.quekett.org/ A fair bit of information it seems, but you have to pay to join in order to access much of the site. Since you are in the UK, and new to this (and actually even if you were not) Queckett is one of the best resources available. LOTs of loca...

.. Immersion Oil can be applied directly to a dry specimen of Blood, with no coverslip. Clinical labs do it all the time for CBC's and body fluid smears. No one coverslips grams stains or the like, either. A thin layer first to substitute for the coverslip, then a larger drop when using the oil imm...

PM sent

It's the beige model :D . No blood please. I've seen enough in my career! PayPal is best. I'll PM you my PayPal email address. You can reply with your shipping address. I'll pack it up tomorrow, and send it out Friday with tracking. I'll send the tracking number to you via your PayPal email address....

Hi Moose,

The adapter is in good shape and I do have a spare NFK 2.5x projection eyepiece. $225 for both, including shipping.

Tom

Hi Moose,

I have a Photomicro Adapter L I'd part with, and I think I have a spare NFK 2.5x projection eyepiece, too. Let me check later this morning to be sure the adapter is in good shape.

Tom

Even, During my 40 years in clinical labs, I've looked at many, many thousands of hematology and gram stain smears with oil immersion and no cover slip. In fact, I've never seen anyone use a cover slip unless it is a permanently mounted slide. Just make sure they're dry first! While using a cover sl...

Wow Very, very nice.

Tom

Discipline. No matter what method you use, it will require discipline to succeed. :shock: Treat your microscopy as a scientific examination, and the photography as part of a method of recording that examination. The other part, just as necessary, is consistently recording metadata. The key is consis...

CE, We never had NC objectives in the hematology labs I've worked in, and never used cover slips on non-permanent slides. We always spread a drop of immersion oil across the dried blood smear for low magnification to eliminate the diffraction caused by the dried cells. If, after we added another dro...

MicroInspector, Stuck? Really? Turn you imagination and curiosity loose! If you can get it under the objective, hold it still and and figure out how to light it, pretty much ANYTHING is fair game. That gives you effectively an infinite number of choices :shock: . Experiment! You can spend your entir...

Kalleboy,

Really? Go to Google and type "uses for a microscope" or some variation thereof. Hit "Enter". Read. A lot. Think. A lot. Read some more.

Tom

Here you go. Page 6 from an intact BHTU manual. Not all that useful once you see it. But until you do, you just never know!

Tom

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 ...

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...

Tom

VERY nice! 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?
