Here is a section of human bone at low power. Notice how clearly you can see the Haversian canals and, if you look closely, you can make out the Periosteum. I will try to get a high powered view that shows the lamellea.

I guess I'm not gonna get any answers to the technical questions I asked Celestron about a certain microscope, the 44110. The b-----ds, anyway. I wanted to know the eye relief (since the eyepieces are not highpoint and I wear glasses), something about its claimed Koehler illuminator and whether inserting an eyepiece reticle would degrade the image.

I'm surprised. I have never had a problem with Celestron. I will see if I can find the information for you. If I do I will let you know.

I'm sorry Clyde, but I could not find the information you were looking for :( If I do happen to find it I will let you know. Let me know how it goes :)

Thanks, Albert. The ads and the spec sheets just don't tell the whole story.

Scorpions - Wind Of Change

Sorry, I've been busy. I most likely won't have new pics for a couple of days. I just need to get through these last few days of tests and then I will have plenty of time to get some updates for all of you.

---

I was going to get some updates today, but a power outage stopped me from doing so :( I will try again tomorrow or perhaps later tonight.

. . . in the meantime: You might like seeing this:

Growing bone, rabbit - H&E

The cartilage model has almost entirely been transformed into bone. The only remaining cartilage is found in the epiphyseal disk. Zones of cartilage proliferation, hypertrophy and calcification are visible at high magnification, but only on one side of the epiphyseal disk - towards the diaphysis, which increases in length as the cartilage generated by the epiphyseal disc is transformed into bone.

Osteoclasts may be found on the newly formed trabeculae or associated with parts of the cartilage scaffold.

Draw the region of the epiphyseal disks. Identify in your drawing the epiphyseal disk and the bone of the epiphysis and diaphysis. Indicate the direction of cartilage proliferation in the epiphyseal disk and the direction of bone growth.

Great posts Richard! Thank you very much for contributing to this thread :) I will have to hold the updates off to tomorrow. I especially like the one of the growing bone....

Very nice microphotos, Richard. I enjoyed them. I think the powers given are inconsistent, though. And, of course, the power depends on how big the picture looks on the screen, too. Probably the best thing to do is to put a micron scale near the important part of the photo or at the edge of it. The colors really look nice!

Finally, some more micro graphs! Here is some filamentous green algae. If you look closely you will notice the nucleus and maybe even the nucleolus of some of the cells.

Here is some human red bone marrow:

I am running out of specimens! If you have any suggestions for things that you would like to see that would be easily obtainable please post them. I plan to order a few more slides later this week, but until them I am low on ideas.

I would say so Albert. Your thread is quite interesting (even if I haven't been commenting much) My son comes home from collage today. He's going to find this very interesting, & I'll see if he has some ideas.

Thanks AE! Cheers!

What is your son studying? Enjoy your time with your son and thanks!

Not a suggestion, but a question (probably due to my ignorance of microscopy): in a lot of your pictures there is a needle-shaped object, the tip of which seems to point to the middle of the picture. My questions are: 1) what is that, and 2) why is it there?

On second thought, maybe a suggestion too: ever thought about crystals? Simple stuff like sugar, table salt and what have you can make very pretty pictures when using the right illumination. Simply let a solution of the stuff dry on your object glass. More exotic stuff (salts of cobalt, cupper, chrome) are more difficult/expensive since you would have to buy them at a chemist. Iron (rust, or rust dissolved in acetic acid resulting in the acetate) might be nice. Well, I guess that there's lots of non-biologic samples that might be interesting. How about water (ice) crystals, or maybe more amorphic materials like soot?

John.
