Ascorbic Acid comparison:- Microscope images

I suppose this is the right place to post given the technologies for illuminating the sample are based on pre twentieth century classical physics for the theory of light.

The images of the same sample were taken through a stereoscope attached to a Pentax k-r.

Image 1 uses polarized light.
Image 2 uses ordinary light.
Image 3 uses a dark field or diffracted light.

The stereoscope was modified to accommodate the different light sources.

As you can see there is far more variety when compared to astroimaging.

Regards

Steven

That's really interesting Steven. What is the Magnification factor here?

Thanks Trevor.
The magnification based on the cameras live view is around 95X.

Using various optical combinations I can vary the magnification from 60-460X.

The attachment below was taken at 230X using a tele-extender

That is neat Steven.
Have you ever observed copper sulphate solution evaporate?
It is exciting seeing crystals appear in an instant as the solution dries up.
I must do a little movie of such.
I have been using a $70 plastic microscope from jaycar.
I got it for my daughter but made the mistake of showing her live dust mites...they put her off...stopped me getting a better unit.
Still this little thing had a camera and great for starting out if you keep mag down.

Copper sulphate is one of the prettiest non-metallic substances there are.

I recall copper sulphate as being a very effective desiccant.
When heated the blue crystals form a white powder and is frequently used in laboratory desiccators.

I saw a similiar affect with Magnesium Sulphate (Epson salts). The end affect reminded me of the surface of Callisto.

I agree.
I would grow large crystals. Pity they were not tuff enough for jewlery

I made it and used it.
I think to keep sodium nitrate dry trying to make an alternative gunpowder.

Yes that's a good one.
Even common salt evaporated is interesting.
