Re: Gastrotrich + ?

Many thanks gekko. You can see the cilia if you really try. Now that I think about it I should have made a special effort to try and capture that characteristic. However locomotion is clearly by cilia movement - effortless. I was amazed how fast the poor guy got swallowed up. Agree. A little frighte...

Gastrotrich + ?

16x, about 40µm at its widest point and 500 long, Oblique, Olympus E-p2

I have not managed to identify Mr Hungry, seemed to have very fine cilia on the edges. Just about visible in opening scene on its posterior.
I apologize for the smudges. On the hunt for them now.

Re: Zeiss Standard gets a new home

Looking much better.
Only other thing you might try is to remove the bulb, rotate it 180 degrees and put it back in.
The filaments are sometimes a little off center.

Re: Zeiss Standard gets a new home

A couple more photos in case you are still having a little trouble. The first one shows the illuminator joined to the collector tube. If you remove it from the base it is easier to work on and one can see by eye if it is pretty much centered. http://i1368.photobucket.com/albums/ag171/mapologo/x1_zps...

Re: Zeiss Standard gets a new home

The reason the filament moves in an ellipse as you rotate it rather than around its own axis is because it is not centered. To center it you need to either screw in or unscrew the pins on the collecting tube - see images for their location and where they are accessed from. If complete they consist i...

Re: Zeiss Standard gets a new home

This is my microscope with the condenser removed and a tracing paper placed over the stage. Notice how the filament is centered on the objective. It is a bit dark, should have turned more lights on.

Re: Zeiss Standard gets a new home

I don't quite understand where the image of the filament is focused. Is the condenser removed? The image of the filament should not be visible at the level of the slide with the condenser in place. Apologies if I'm barking up the wrong tree. At the moment we are trying to center the filament direct...

Re: Zeiss Standard gets a new home

I would not recommend looking at living creatures until you have the microscope correctly set up.

I would suggest that you buy a Stage Micrometer, you will need one anyway, size does matter in microscopy, they are available on ebay from China and are not too expensive. Use that to practice on.
