Thanks Gerard. My microscope has separate fine and course focus knobs. I contacted the dealer (Amscope) and they told me to toghten by turning the fina and course knobs in opposite directions. I tried that and it seems to have worked more or less.

I wish I knew. Spectacular images.

Interesting and complicated image--well shot.

Microscopes are not like magnifying glasses. They work on the basis of interference patterns that break the white light into color bands. They fail to resolve images when the interference patterns are not present. I think the color consequences on microscopic images are unpredictable. There doesn't ...

Thanks KD

My fine focus knob is proving hard to use. Often I achieve good focus with the rough adjustment then use the fine adjustment to refine focus further or to focus in and out and the entire focus slips. How does one tighten the fine focus?

I have an Amscope M100 mono lens with separate fine focus knobs.

wow! That's impressive.

The cucumber's large yellow flower has many tubes and spikes. It looks like a high-tech device under the microscope.

Thanks Perry. I have just learned how to use the microscope that way.

It doesn't look like one to me.

I've been making cultures out handfuls of dry grass (grass long sitting on the ground). I have had some cultures where all the microbes died out quickly, but this time it seems to be working. They microbes are living in the grass. I did an experiment to check that. It's here http://www.microbehunter...

The tiniest flower is so articulate, I can explore for hours.

In actual fact, I have a feeling that microscopes don't much like up-stage lighting. My microscope seems to respond better--make better use of light that passes through the condenser. I modified my use of the fiber-optic cable to pass it through the condenser via the side of the filter holder. Now i...

I learned a lot from this.

There is a lot to see if you look really really close.

Small, thin yellow petals are just covered with pollen grains. The grains appear spherical with tiny bumps and imperfections (40x and 60x objectives).

Thanks Michael. I still can't use it with the higher powered objectives. The lenses block the light beam.

Since I bought my microscope, I've been trying out stop filters, means of making shadows, and being able to see opaque subjects. I bought some fiber optic cable which finally arrived today. Now I'm working on the mechanics of creating a system (with no resources except pieces of plastic and tape). I...

Thanks KD

I dressed it up like a painting.

It saves me from having to use those block filters.

A biofilm forms after a time. Protozoans feed at the fringes but those who get caught in it may become cysts which may eventually get buried in it. The biofilm begins to look like a kind of archeological dig.

All of us are using a variety of technics to control the light to improve definition and make our images more interesting. I am using a small USB powered flashlight that acts as a stop filter and a source of adjustable substage light. I also bought (in the dollar store) a set of ting LED lights I'm ...

To observe microorganisms I have been collecting dry grass and letting it infuse in water for a few days. Lo and behold rotifers, ciliates, and even ameobas appear. I wanted to see how the dry grass holds these creatures. I took a measure of dry grass, put it on a microscope slide and added a drop o...

My old grass culture yielded something I never saw before.

Beautifully lit. How did you do that?
