If you haven't found the answer to this yet, please give brand and model number of the scope. More help may be available through personal experience of others.

I had this problem with a new scope once. It took a while for me to find that tiny screw on the occular tube which needed tightening. Take your time. Look carefully.

True. Rotate the objective to see if it is the cause. Clean the top lens on the condenser. Check the entire light path for cleanliness, including the lens on the bottom of the head. Disassembly of microscope head is not recommended. Do spots disappear when you focus on a specimen? If they do, don't ...

I've learned a lot from this forum in recent years and have appreciated it all very much, but this morning there a nine new posts concerning sports. It has reached the point of being more than disappointing.

So I noticed. Some search engines just can't be trusted anymore.

Yes. But finding the right lens may be difficult I sometimes wonder if the people who make lenses for spectacles might be able to help in that regard but I have never asked .

That is a very beautiful Ernst Leitz Wetzlar microscope. That flat round object under the eyepiece with a knob on it should have a rotating disc inside that moves when you turn the knob to adjust the degree or angle of polarization . It's a winner and it's rare. Could be worth real money. Wetzlar wa...

Lots of folks here have lots of experience with cameras. They can explain stitching or stacking if you need the info.

Unable to buy scopes I went for better cameras, and I finally have seeds that have sprouted so the next experiment starts tomorrow after spending two years playing with pond water. By the way, I bought a bag of planting mix to work with plants. I put some in a petri dish and added water. Looking at ...

The size of the image produced by your camera is much larger than what you see through the eyepiece because of the size of the camera sensor. Most microscope camera have a sensor of 1/2. That will give pretty close to a 40x image with a ten x objective. It makes it seem like your are using close to ...

I only have 16 microscopes and now my wife says I can't have any more . Darn.

Thanks! Now I understand. I have the ping pong balls and will make a couple of these things, but you make me think that a bigger thing made with similar materials might enhance imaging with the stereo scope as well .

Anybody know of a good time lapse app for windows 10. They have a lot of them but I would like a recommendation as to which of them works well.

Hi Pete and Scar. I am using a microscope slide. Glued to it with water proof glue is a small rectangle made with my 3d printer. On top of that I am placing a very thin piece of clear acrylic, also with water proof glue. The top of the rectangle has been cut off to allow for adding hydrponic water,a...

1. What are the specimens. If they are pond water type, leave the cover on the help prevent evaporation and don't worry about oxygen.. Mine are always in sealed jars. 2. These are best kept where they get some light, but the window sill might be too much to just be left there all the time. 3. Collec...

i AM BEGINNING RESEARCH WITH THE GERMINATION OF SEEDS AND THE GROWING PROCESS OF PLANTS. WE HAVE ALL SEEN THIS IN THE PAST IN A MACRO SETTING, BUT MY DESIRE IS TO DO THIS MICROSCOPICALLY WHILE THE PLANT IS STILL ALIVE TO RECORD ITS GROWTH OVER TIME AND TO COME TO A BETTER UNDERSTANDING OF HOW PLANTS...

If over 40 years old, it is advisable to change all capacitors in the circuitry, whether ceramic or electrolytic. Capacitors just give up the ghost over time, even if they are not being energized.

Electrolytic capacitors are voltage specific, meaning plus to plus and minus to minus. The positive pole will be marked with a plus sign. Hook that up backwards and the explosion could be a real mess.

I would not advise attempting to replace an electrolytic capacitor with a ceramic capacitor. That is unwise. I would replace it with a more rebust electrolytic capacitor, such as a 0.1 micro Farad, 600 or 1000 volt capacitor. Before replacing it, you need to check all circuit components. Did anythin...

It reminds of the disaster Coca Cola brought upon itself when it changed its flavor. It's possible that the name for microscopes will not change but other things are bound to.
I think it is a huge mistake if for no other reason than the company itself introduces doubt.

The sensor of the camera tells the tale. Most are listed in camera specs as 1/2. The apparent size of the image changes if the sensitivity of the camera changes. 1/3 will give a different image than 1/2. It's not really the price of the camera. It's the sensitivity . I have some cameras that were pr...

Most microscope cameras deliver what appears to be the size of nearly a 400x image when you are expecting a 40x image. Without getting technical, your experience is normal.

Unfortunately many manufacturers just don't understand slide storage. You can purchase wooden or metal slide storage cabinets which are intentionally designed to hold or store the slides in the wrong orientation rather than correctly as described above, and they must be really proud of them based up...

Good luck. Center. Center. Center

Louise,
I dint believe you will need a secondary tube. My epi scope has only one.

AMSCOPE PREPARED SLIDES STINK! THEIR MOUNTING MEDIUM SETS UP WITH SPECKLES OF CRYSTALIZATION, RUINING ANY IMAGE IN DARK FIELD, POLARIZATION, AND RHEINBERG FILTRATION. Amscope microscopes are fine. You may have to center the lamp to assure good brightness, but all of my fifteen scopes are Amscope and...

Ok. I see what you did and how to use it. Did you do it for something specific and what prompted you to need it?

Thanks Pete.

Looks to me like an adaptor ring used to make a 20 mm objective fit a 25 mm nose piece. I'd like to find a source for such things at a reasonable price.
