Have you considered doing permanent diatom slides?
Now there is a scary thought. I do admire those that can make them!

Re: SWIFT SW380T assistance required

Do higher end microscopes redirect a higher percentage of the light? Most do either a 100/0 and 0/100 or 100/0 and 20/80. Some have 3 positions. ... with a 25x eye piece and a 40x objective the image ... You really want the main magnification where possible to come from the objective. If you want 1...

Actinocyclus subtilis

Planapo 63x/1.4, DIC, 65µm, stacked in Photoshop, Marine sample, Alboran Sea.

Now that they are letting us out and about I went down to the port and collected another seaweed sample.

Always seem to be plenty of diatoms to be found when one picks some up with tweezers and taps lightly on a slide.

Re: Improving Top-Stage Lighting Using a Smaller Aperture on the Lamp

I am an amateur photographer. A lot of people in my camera club hate the way I use processing, even in regular photos.
If you do require help with your setup we would need to see plain unaltered images. I think 'Art' benefits from a good starting point.

Re: SWIFT SW380T assistance required

There does not seem to be a way to redirect the light in the trinocular head, so you are most probably getting a 50/50 split between the photo port and the binocular. That effectively means that you get 25% out of each eyepiece. That should be ok for most situations. Remember that for best results t...

Re: Wierd behaivor from unknown microorganism

Hmm you may want to open your substage Iris a bit it will increase your resolution and obscure the out of focus schmutz somewhat. Also make sure your condenser is just below the slide - say a millimeter or two. What objective did you use? It is a little small to see much detail. It seems to have a ...

Re: Zeiss WL Modified with Tilt Top

Turned out very well!

I wonder if it was designed to take the four-axis Fedorov stage, which out of the Standards will normally only fit on the GFL (fixed stage and rising nosepiece)

Re: battery adapter

Thanks for the offer. I placed an order for one from china before I saw Roldorf's post so a little patience and I am basically sorted.
I run my Olympia E-PLx cameras off a 7.5VDC power supply.
Shop bought or jury-rigged?

Anyone come across a battery adapter that connects to an external power supply for the olympus E-P2 M4/3

A big reason why isopropyl alcohol should be kept in a tightly closed container is that it is very hygroscopic, at least until it dilutes itself down to 65% (35% water).
Now that is useful info.

Nice video, sharp and clear!

Is that insert on the bottom right at 40 sec your doing or youtube? Tis a little distracting. It appears just as he grabs another ... not sure what they are, Trachelomonas perhaps?

Welcome jemarch, I am sure you will enjoy your journey into microscopy.

When you say Zeiss Junior KF is that the black 1950's microscope you are talking about? Can you supply a seller photo (until it arrives)
