Hello, not the AmScope B100B-MS, as it does not seem to have a light intensity control. The other Amscope ones are fine in this respect. The knobs for the mechanical stage are also horizontal, which is inconvenient. If you look at the objectives, you will see that some of them use the same, so there...

The bright spot could be due to the reflection of light inside the phototube. once had a similar issue. Closing the koehler diaphragm resolved this (should you microscope have this), alternatively you might want to check if the inside of the tubes are sufficiently dark, to reduce reflection.

Hello, This is called "tethered shooting". Here is a link explaining it for Canon cameras. http://www.jibble.org/canon-tethered-shooting/ If you use the Canon software, then you can directly store the images directly on the computer. The software also allows you to take automatic interval pictures, ...

Hello, Yes, it is correct that hot linking might be also considered "stealing" of bandwidth or of the image, because you make it appear that someone elses image is your own. And indeed there have been cases like this before. I remember from the news that a company once sued for embedding weather cha...

Intresting: when creating the post the image will hotlink, later it will not show. Even though there is a direct image address. Clicking on the link directly will forward to the homepage. http://theqcc.hennig.ca/Jun/17/Dolerite%20100x_125.jpg right-clicking can be enabled by disabling javascript, bu...

Hello, The hotlink and copy protection makes it more difficult to hotlink and copy images, but once something is online, it is out there. You can always make a screenshot and then save the picture this way. I think that putting a watermark is generally a good idea, and also reducing the image resolu...

Micscape magazine has a full article about this microscope:

Hello,
There are, unfortunately, always posts, which are either ads or simply copy-pasted fromother posts. I would indeed prefer private messages and I will then remove them. I have already made the registration questionmore difficult, but there are always posts and members that sneak through.
Oliver

The index needs to be updated, I will do this.
Oliver

Should work now..... hopefully!

Dear forum members, Several members have experienced quota problems. The forum software limits the upload to 100MB (this is called the "quota") and the maximum storage space that the forum allows per user. I highly encourage all users who experience this issue to register at a free photo hosting sit...

Hello, A microscope that is put together is normal. the white spots appear to be reflections of some light. i assume that the camera takes the placeof one of the eyepieces. cover the second eyepiece, it could be that light entering the second eyepiece causes these reflections. the reflections stay t...

Self-diganosis rarely works. 1/3 of the dry weight of stool are bacteria anyway. It is impossible in most cases to determine the organism directly from observation. You need biochemical or histological tests to do this. Chances are too big that you are simply observing indigestible food matter, etc....

Just guessing: maybe these are able to hold so-called swan-neck lamps for illumination of the specimen from both sides. Swan-neck lamps have a lamp on the tip but can be bent into place, because the "neck" is flexible. But I am only guessing.

Hello, JPG: lossy compression, image quality goes down when saved, but low image size and the loss of quality can be adjusted and in most cases not noticable. Used for the web due to small size, it is the standard for photography and can/should be used TIFF: loss less compression, used when processi...

The stacking is due to the drying of the blood. Some alternative medicine advocates see in this rouleaux formation (as it is called) some diagnostic value, but there is noscientific evidence for this. The spiky red blood cells are due to osmotic imbalance, as the blood dries. It can also be that som...

Hello,
Do not attempt to fix anything, you might end up making things worse and then the seller has an argument for not exchanging the microscope. If the "ring bump" is due to external force (bent metal?), then maybe there are other things also wrong. Mictoscope should be exchanged.

Hello, This forum is so active, that I almost overlooked this thread... Sorry for the late reply. Basically any method is fine. If I get your OK in advance, then I will simply pull the images posted on the forum and re-use them in the magazine (using your name, etc.). This is only meaningful, if the...

I should have read the thread better!!
A big thank you to JimT and 75RR as well! There is one question left, however, and this is how to attribute the pictures in the magazine. What name do you want me to include beneath the pictures?

All the best, Oliver

A big thank you to Gekko and to Manfred to giving me permission! General info: While it is possible to only publish the pictures on this forum (or link them), it is sometimes better to send me the originals of higher resolution for republication. If you use photo hosting services, then the image siz...

Hello,
Bacteria are unlikely, because an internal structure is visible. Most bacteria do not have internal structures visible with light microscopes (except PHB deposits or endospores).

Hello, My interest in imaging blood cells is purely from an Art/Micrography/Microscopy perspective and not diagnose/analysis. OK. For your information, the second video is a textbook example of pseudoscience: it claims to be scientific, by using scientific terminology, but it is not. I wonder if the...

Thanks to Oliver whose behind-the-scenes efforts make this forum available to us.

And thanks to the whole community, which keeps the forum active and alive with valuable contributions!

These structures look like plant trichomes:

1. rotate the camera. if the position of the glow stays, then you have a camera issue. 2. remove the camera from the microscope and hold it to an even light sourse. check if the glow remains. aif so, then the problem is with the camera and not the microscope. I suspect that it might be a problem wit...

if you want to use pond life, then you use water, of course, and then coverglass with oil. But this is difficult, because the pond life swims in and out of focus, and the depth of field of the 100x oil objective is quite low. You must make sure that the water film is sufficiently thin. I always used...

Hi, Do's: remove oil after use to reduce dust accumulation, but do not overclean to avoid scratches (clean lightly only, using lens paper) use oil as mounting medium (no cover glass), no water. use synthetic oil, natural oil can become hard make sure specimen is flat (eg bacteria sticking on slide) ...

Hello, If you look at the photo contest winners (Nikon, Olympus have microphotography contests), then I think both aspects count. The images are pretty, but also are able to illustrate interesting scientific concepts or unusual perspectives or views. So they are "absolute" (i.e. absolutely pretty, a...
