Re: HOW TO FIND SHARK TEETH
Fossils hey? I never would have guessed. I had a white one when I was young, a necklace thing but the black ones do have appeal.

Re: another marine beastie aka Sea Dragon
About 750µm, which would make it a mini Sea Dragon Actually did a google search on Sea Dragons - turns out someone used the name for a cousin of the Sea Horse so I really should come up with another provisional one. Interesting find. I searched bing images under a variety of term and found nothing ...

Re: Another Marine Nematode (ruler straight)
At 1000um it would seem possible that you could "curl" it up yourself, like with a fine needle say. Have you ever manipulated a subject thus 75?

I wonder what purpose those forked stalks at the top of the first image perform. Nothing on these creatures is an ornament, everything has a function I believe.

Re: 3 Marine Diatoms
Nice captures 75, so much detail I have to keep reminding myself they are microscopic organisms and not larger subjects. I look forward to the day I buy the dedicated camera for my scope.

I am new to this hobby. Please, could any one tell me if buying a used OLYMPUS BX40 is a good choice to start? I suppose it's all relative to your income.

Re: Greetings from Spain.
Welcome Adolfo, it's certainly a fascinating hobby. Using sunlight as a light source, if it can be arranged, would be the best illumination too I believe. The most natural for the eyes so to speak.

Re: newbie looking for first microscope
In terms of your desire for a digital microscope, I'd suggest buying a used top quality lab microscope from the 70's - 90's and then add a digital camera to it. I concur Paul, if you have an eye for quality engineering and precision controls you can't go past the older ones IMO. Dollar for dollar w...

Re: Does anyone use a 4x objective?
Make sure you have the nosepiece opening covered in the meantime. I have caps on all the empty sockets if that's what you mean I never use the 4x on my more basic Olympus ECE model because when I open the field diaphragm to maximum to allow a fully illuminated fov, said view becomes degraded for so...

Beginners Interactive guide to relative microscopic size variations
I found this quite useful in giving me a general sense of scale for what I was looking at under the microscope. Just move the slider under the picture to zoom in to greater and greater magnifications.

Can you put a leaf off the plant under the scope? They grow on the leaves I read.

Does anyone use a 4x objective?
I was wondering if these are used regularly by any posters here, and if so to what purpose. I have read they are for scanning, getting a general overview, but are there specific subjects viewed with a light microscope for which this is a good choice of objective, assuming 10x eye-pieces.

Dead-right my friend. We all have to start at the beginning. You'll find your technique will improve very quickly indeed - remember to keep the sample and the blade wet and 'slice' rather than chop if you can. You'll be amazed what can be achieved with basic hand-sectioning! Good luck, let us know ...

Seemed quite complete - thought it would allow some detailed viewing. That it does. Do you think it died of old age etc, or was this the result of growth, like when a snake sheds it's skin? If the former it would be good to see a time lapse of the internals being eaten out by smaller organisms. Tha...
