This microscope is a rare artifact for this period in Canadian history having been used by a woman amateur naturalist in the colonies, while accompanying her husband on his surveying and military missions. It is a portable microscope used by Caroline Bucknall Estcourt (1809-1886) (born Caroline Pole Carew), wife of a British officer, James Bucknall Bucknall Estcourt (1802-1855). Bucknall Escourt was posted to the Canadian colonies in the 1830s and 1840s. Caroline was an amateur naturalist of some note and a painter. Some of her graphic collections are preserved at the Library and Archives Canada including portraits, sporting scenes, landscapes and her journal.
It is also a significant microscope from 1843, incorporating one of the earliest commercial, portable achromatic lens systems (serial no. 68) made by the well-known instrument maker, Andrew Ross of London. Because of its colourful provenance and technical significance, it is one the most important optical microscopes in the collection.
Taken with a Microscope and attached DSLR camera... I made them into HDR's but otherwise did not feel like editing them. Sorry.
While my main camera is in the shop, it's a good time to take advantage of the almost-identical diameters of my pocket Olympus Stylus 800 lense housing and my microscope oculars. A nice length of electrical tape provide a functional interface. Here I decided to examine both sides of a bi-colored feather I found. I illuminated feather edges at 40X with light sources from the front and back. The main quill (the "rachis")branches out with another sturdy limb (the "barbs") before further branching into the tiny soft branches (the "barbules"). (Um, I had to look up those terms...) The colors on this feather are on the hard components only. OK. Move along; nothing more to see here...
Incredible gift from Pooja's grandfather . . . his company, Labomed, manufactures and sells microscopes for academic and medical professionals.
This microscope illuminates from above instead of below, which offers a big advantage: the objects being studied don’t have to be prepared in ultra-thin slices. Kids can simply aim the incident light microscope at anything that catches their fancy—articles of clothing, toys, plants, even their own skin. The 50x enlargement delivered thereby provides astounding new impressions and insights.

These are CSI styled diatoms, dead for about 40 years. Magnification was about 1000 times, I used a Olympus BH microscope for this picture. But I forgot to set the aperture on the microscope right, so that is why it has these ugly corners :P
30 seconds exposure time to visualize the amoeba's movement.
Taken in polarized light with phase contrast. Size of the amoeba is about 70 micrometers.

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.
