Bought this cool attachment for my phone that let's me take super close ups of things , this is a braid I did on my Art Class robeccas hair (:
Using Helicon FB Tube.
Hand held in the Museum of the History of Science in Oxford.....Not too bad, I could have had more images for the stack if I hadn't got all self conscious about the bystanders...and me rattling off shots like a machine gun!

On distingue clairement des cellules sphériques plus volumineuses (Hétérocystes) qui ont la faculté de fixer l'azote de l'air pour le fournir aux cellules ( maillons plus petits de ces chaines) afin qu'elle puissent réaliser la photosynthése qui leur permet de fixer le carbone contenu daéns l'air sous forme de sucres. C'est ainsi que dès l'apparition de ce type de cyanobactéries sur Terre (1 à 1.3 milliards d'années), ces dernières ont commencé à réduire le CO2 (dioxyde de carbone) de l'atmosphère primitif (alors dépourvu d'oxygène) pour absorber le carbone et rejetter l'oxygène. C'est ainsi que s'est opéré l'accroissement de la teneur en oxygène de l'atmosphère terrestre que nous connaissons aujourd'hui.
Lorsque nous rejetons du CO2 dans l'atmosphère, nous détruisons nos propres ressources vitales issues de centaines de millions d'années de travail de ces cyanobactéries, auxquelles pourtant nous devons d'avoir pu voir le jour il y a à peine 1.5 million d'années. Ce processus porte un nom : AUTODESTRUCTION ...

I left some water on the kitchen window sill so I could study it under the microscope. There were at least 5 distinct organisms living in there and it was fascinating to watch! Here is a video of a couple of them.
Taken with a C Baker microscope at 40x magnification, with a Canon 1100D attached to the eye piece with a special T-adapter. I don't have a proper working light source for this microscope so the images are darker than I would have liked.
The microscope was broken but I kept the eyepiece to use as a powerful hand lens.

Low key colour image of a No. 3/A 100x magnification student microscope made by Signalling Equipment Ltd (SEL) of England.
Leitz SM Medical Microscope setup for Photomicroscopy. The microscope was made in 1958, the first year of production for this model. It includes a Swing out Abbe condenser, coaxial mechanical stage, four objectives - 3.5/0.10, 10/0.25, 45/0.65 and an OEL 100/1.30. I replaced the regular "S" binocular head with an "FS" Trinocular head. Attached to the trinocular head is a Leitz MIKAS camera adapter. The MIKAS adapter allows for the attachment of any LTM/M39 camera. In this photo I have a Nikon M-35 microscope camera attached. I can also adapt a digital camera, an M42 camera or just about any camera with the proper adapter.

"From the beginning, it was the snowlfakes that fascinated me most"
Dubbed as “Snowflake”, Wilson Alwyn Bentley (1865-1931) was a pioneer in snowflake photomicrography. As a child he was fascinated by the natural world, and by the age of 19 he became the first to successfully capture a snowflake photograph with the help of a feather, a microscope and a camera. Bentley photographed thousands of individual snow crystals during his career, some of which we are showcasing in this Public Domain collection. We have digitally enhanced these amazingly detailed photographs of these winter’s wonders for you do download and use under the CC0 license.

taken through a microscope using phase contrast and polarized light. The size is about 70 micrometers.
Professor Christina Hydron is pleased with this new equipment... :D I bought her again recently, kinda missed her... I can't remember what happened to the previous minifig whether I sold it or gave it away...
The microscope is seen from one of Lynn's older photos where she bought set from a fair or something, with laboratory stuff...

An interesting look at everyday things.
I bought a cheap USB powered Microscope and then started exploring. Some of the images were very unexpected so I thought I would post a few.
Held the microscope flush with an LCD screen
