Re: Tips on Buying a Microscope and suggestions for What to look at

In my opinion no one should ever buy toy microscopes, telescopes etc. and not even cheap entry level ones. These kind of instruments with plastic optics or wobbly mounts and poorly put together will only bring frustration instead the pleasure of knowledge and will soon be abandoned, thrown away and ...

Re: Paramecium sp. feeding on bacteria

Thanks a lot guys, I always thought that there must be a chemical way of communication between the bacteria similar with pheromone system in animals.
No idea if I'm right, don't really have time to look for studies abut this but I bet there are people that can answer the question.

Re: Spathidium sp.

Hi, it's called darkfield illumination and is very easy to get for objectives up to 10x.
What you need is a black stop centered under the condener.

Re: Paramecium sp. feeding on bacteria

No idea how it happens but I've seen this behavior even at very large colonies, they are forming this kind of borders over areas leaving the interior completely empty, not necessarily ring shaped.

Re: Stentor

Again both a good catch and very nice Darkfield! Are they mail order animalcules? Note: Much easier to read without the chasing around ... :) No, I'm not ordering cultures, just using what I can find around me. The Stentors came 2 weeks ago when I changed my fish tank water and cleaned the filter. ...

Superb! I admire your stage control... or are you cheating and using a joy stick? Either way, you've made a beautiful production, both informative and entertaining.
